//[END OF VERSION]

  K.O.L. - is a set of objects to create small programs
  with the Delphi, but without the VCL. KOL allows to
  create executables of size about 10 times smaller then
  those created with the VCL. But this does not mean that
  KOL is less power then the VCL - perhaps just the opposite...

  KOL is provided free with the source code.

  changed by me) authors are noted in the source.

   Please note, that KOL does not use keyword 'class'. Instead,
   poor Pascal 'object' is the base of our objects. So, remember,
   how we worked earlier with such Object Pascal's objects:
|<br>
   - to create objects dynamically, use P<objname> instead of
     T<objname> to allocate a pointer for dynamically created
     object instance;
|<br>
   - remember, that constructors of objects can not be virtual.
     Override procedure Init instead in your own derived objects;
|<br>
   - rather then call constructors of objects, call global procedures
     New<objname> (e.g. NewLabel). If not, first (for virtualally
     created objects) call New( ); then call constructor Create
     (which calls Init) - but this is possible only if the constructor
     is overriden by a new one.
|<br>
   - the operator 'is' is not applicable to objects. And operator 'as'
     is not necessary (and is not applicable too), use typecast to desired
     object type, e.g.: "PSomeObjectType( C )" inplace of "C as TSomeClassType".
|<br>
|<hr>
     Also remember, that IF [ MyObj: PMyObj ] THEN

     NOT[ with MyObj do ] BUT[ with MyObj^ do ]

     Though it is possible to skip '^' symbol when accessing member
     fields, methods, properties, e.g. [ MyObj.Execute; ]

  Several conditional symbols can be used in a project
  (Project | Options | Directories/Conditional Defines)
  to change code generated a bit. There are following:
|<pre>

  PAS_VERSION           - to use Pascal version of the code.
  PARANOIA              - to force short versions of asm instructions (for D5
                          and below, D6 and higher use those instructions always).
  USE_NAMES             - to use property Name with any TObj. This makes also
                          available global function FindObj( name ): PObj.
  (USE_CONSTRUCTORS     - to use constructors like in VCL. Note: this option is
                          not carefully tested!)
  USE_CUSTOMEXTENSIONS  - to extend TControl with custom additions.
  UNICODE_CTRLS         - to use Unicode versions of controls (WM_XXXXW messages,
                          etc.)
  USE_MHTOOLTIP         - to use MHTOOLTIP.
  NOT_USE_OnIdle        - to stop using OnIdle event (to make code smaller
                          if it is not used actually).
  USE_ASM_DODRAG        - to use assembler version of code for DoDrag.
  ENUM_DYN_HANDLERS_AFTER_RUN - to allow all the events handling even when
                        AppletTerminated become TRUE.
  ALL_BUTTONS_RESPOND_TO_ENTER - obvious (by default, buttons respond to key
                        SPACE, since those are working this way in Windows).
  ESC_CLOSE_DIALOGS     - to allow closing all dialogs with ESCAPE.
  KEY_PREVIEW           - form also receive WM_KEYDOWN (OnKeyDown event fired)
  OpenSaveDialog_Extended - to allow using custom extensions for OpenSaveDialog.
  AUTO_CONTEXT_HELP     - to use automatic respond to WM_CONTEXTMENU to call
                        context help.
  NOT_FIX_CURINDEX      - to use old version of TControl.SetItems, which could
                        lead to loose CurIndex value (e.g. for Combobox)
  NOT_FIX_MODAL         - not to fix modal (if fixed, click on any window
                          activates the application. If not fixed, code is
                          smaller very a little, but only click on modal form
                          activates the application).
  NEW_MODAL             - to use extended modalness.
  USE_SETMODALRESULT    - to guarantee ModalResult property assigninig handling.
  USE_MENU_CURCTL       - to use CurCtl property in popup menu to detect which
                        control initiated a pop-up.
  NEW_MENU_ACCELL       - to use another menu accelerators handling, without
                        AcceleratorTable
  USE_DROPDOWNCOUNT     - to force setting combobox dropdown count.
  NOT_UNLOAD_RICHEDITLIB - to stop unload Rich Edit library in finalization
                        section (to economy several byte of code).
  DEBUG_GDIOBJECTS      - to allow counting all the GDI objects used.
  CHK_BITBLT            - to check BitBlt operations.
  DEBUG_ENDSESSION      - to allow debugging WM_ENDSESSION handling.
  DEBUG_CREATEWINDOW    - to debug CreateWindow.
  TEST_CLOSE            - to debug Close.
  DEBUG_MENU            - to debug menu.
  DEBUG_DBLBUFF         - to debug DoubleBuffered.
  DEBUG                 - other debugging.

  PROVIDE_EXITCODE      - PostQuitMessage( value ) assigns value to ExitCode
  INITIALFORMSIZE_FIXMENU - form size initially is really the same as defined at
                          design time even for forms having main menu bar

  GRAPHCTL_XPSTYLES     - to use XP themed Visual styles for drawing graphic
                          controls. This does not affect windowed controls
                          which visual style is controlled by the manifest.
  GRAPHCTL_HOTTRACK     - to use hot-tracking also together with XP themed
                          graphic controls (otherwise only static XP themed
                          view is provided). Also, turn this option on if you
                          want to handle OnMouseEnter and OnMouseLeabe events
                          for graphic controls.

----------------------------------------------------------------------- }
//[TCanvas DEFINITION]
  TCanvas = object( TObj )
  {* Very similar to VCL's TCanvas object. But with some changes, specific
     for KOL: there is no necessary to use canvases in all applications.
     And graphic tools objects are not created with canvas, but only
     if really accessed in program. (Actually, even if paint box used,
     only programmer decides, if to implement painting using Canvas or
     to call low level API drawing functions working directly with DC).
     Therefore TCanvas has some powerful extensions: rotated text support,
     geometric pen support - just by changing correspondent properties
     of certain graphic tool objects (Font.FontOrientation, Pen.GeometricPen).
     See also additional Font properties (Font.FontWeight, Font.FontQuality,

       an application button or a control. (It is not necessary to do so in
       the most cases, even if You plan to work with control's handle directly.

    {* Extra window styles. Available flags are following:
       |<table border=0>
       <L WS_EX_ACCEPTFILES>    Specifies that a window created with this style
          accepts drag-drop files. <E>
       <L WS_EX_APPWINDOW>      Forces a top-level window onto the taskbar
          when the window is minimized. <E>
       <L WS_EX_CLIENTEDGE>     Specifies that a window has a border with a
          sunken edge. <E>
       <L WS_EX_CONTEXTHELP>    Includes a question mark in the title bar of
          the window. When the user clicks the question mark, the cursor
          changes to a question mark with a pointer. If the user then clicks
          a child window, the child receives a WM_HELP message. The child
          window should pass the message to the parent window procedure,
          which should call the WinHelp function using the HELP_WM_HELP
          command. The Help application displays a pop-up window that
          typically contains help for the child window.WS_EX_CONTEXTHELP
          cannot be used with the WS_MAXIMIZEBOX or WS_MINIMIZEBOX styles. <E>
       <L WS_EX_CONTROLPARENT> Allows the user to navigate among the child
          windows of the window by using the TAB key. <E>
       <L WS_EX_DLGMODALFRAME> Creates a window that has a double border;
          the window can, optionally, be created with a title bar by
          specifying the WS_CAPTION style in the dwStyle parameter. <E>
       <L WS_EX_LEFT>   Window has generic "left-aligned" properties. This
          is the default. <E>
       <L WS_EX_LEFTSCROLLBAR> If the shell language is Hebrew, Arabic, or
          another language that supports reading order alignment, the
          vertical scroll bar (if present) is to the left of the client
          area. For other languages, the style is ignored and not treated
          as an error. <E>
       <L WS_EX_LTRREADING>     The window text is displayed using Left to
          Right reading-order properties. This is the default. <E>
       <L WS_EX_MDICHILD>       Creates an MDI child window. <E>
       <L WS_EX_NOPARENTNOTIFY> Specifies that a child window created
          with this style does not send the WM_PARENTNOTIFY message to its
          parent window when it is created or destroyed. <E>
       <L WS_EX_OVERLAPPEDWINDOW>       Combines the WS_EX_CLIENTEDGE and
          WS_EX_WINDOWEDGE styles. <E>

          WS_EX_TOOLWINDOW, and WS_EX_TOPMOST styles. <E>
       <L WS_EX_RIGHT> Window has generic "right-aligned" properties.
          This depends on the window class. This style has an effect only
          if the shell language is Hebrew, Arabic, or another language that
          supports reading order alignment; otherwise, the style is
          ignored and not treated as an error. <E>
       <L WS_EX_RIGHTSCROLLBAR> Vertical scroll bar (if present) is to the
          right of the client area. This is the default. <E>
       <L WS_EX_RTLREADING>     If the shell language is Hebrew, Arabic, or
          another language that supports reading order alignment, the
          window text is displayed using Right to Left reading-order
          properties. For other languages, the style is ignored and not
          treated as an error. <E>
       <L WS_EX_STATICEDGE>     Creates a window with a three-dimensional
          border style intended to be used for items that do not accept
          user input. <E>
       <L WS_EX_TOOLWINDOW>     Creates a tool window; that is, a window
          intended to be used as a floating toolbar. A tool window has
          a title bar that is shorter than a normal title bar, and the
          window title is drawn using a smaller font. A tool window does
          not appear in the taskbar or in the dialog that appears when
          the user presses ALT+TAB. <E>
       <L WS_EX_TOPMOST> Specifies that a window created with this style
          should be placed above all non-topmost windows and should stay
          above them, even when the window is deactivated. To add or remove
          this style, use the SetWindowPos function. <E>
       <L WS_EX_TRANSPARENT>    Specifies that a window created with this
          style is to be transparent. That is, any windows that are
          beneath the window are not obscured by the window. A window
          created with this style receives WM_PAINT messages only after
          all sibling windows beneath it have been updated. <E>
       <L WS_EX_WINDOWEDGE>     Specifies that a window has a border with
          a raised edge. <E>

       Can be used only with a forms to show it modal. See also global function
       ShowMsgModal.
       |<br>
       To use a form as a modal, it is possible to make it either auto-created
       or dynamically created. For a first case, You (may be prefer to hide a
       form after showing it as a modal:
       !
       !  procedure TForm1.Button1Click( Sender: PObj );
       !  begin
       !    Form2.Form.ShowModal;
       !    Form2.Form.Hide;
       !  end;
       !
       Another way is to create modal form just before showing it (this economies
       system resources):
       !
       !  procedure TForm1.Button1Click( Sender: PObj );
       !  begin
       !    NewForm2( Form2, Applet );
       !    Form2.Form.ShowModal;
       !    Form2.Form.Free; // Never call Form2.Free or Form2.Form.Close
       !  end;               // but always Form2.Form.Free; (!)
       !
       In samples above, You certainly can place any wished code before and after
       calling ShowModal method.
       |<br>
       Do not forget that if You have more than a single form in your project,
       separate Applet object should be used.

       When called, see on Stage to get know, on what stage the event is
       activated. And depend on the stage and on what you want to paint,
       return a value as a result, which instructs the system, if to use
       default drawing on this (and follows) stage(s) for the item, and if
       to notify further about different stages of drawing the item during
       this drawing cycle. Possible values to return are:

       CDRF_DODEFAULT - perform default drawing. Do not notify further for this
                      item (subitem) (or for entire listview, if called with
                      flag CDDS_ITEM reset - ?);

                      first time in a cycle of drawing, with ItemIdx = -1 and
                      flag CDDS_ITEM reset in Stage parameter;
       CDRF_NOTIFYPOSTERASE - usually can be used to provide default erasing,
                      if you want to perform drawing immediately after that;
       CDRF_NOTIFYPOSTPAINT - return this value to provide calling the event
                      after performing default drawing. Useful when you wish
                      redraw only a part of the (sub)item;
       CDRF_SKIPDEFAULT - return this value to inform the system that all
                      drawing is done and system should not peform any more
                      drawing for the (sub)item during this drawing cycle.
       CDRF_NEWFONT - informs the system, that font is changed and default
                      drawing should be performed with changed font;
       |</pre>
       If you want to get notifications for each subitem, do not use option
       lvoOwnerDrawFixed, because such style prevents system from notifying
       the application for each subitem to be drawn in the listview and only
       notifications will be sent about entire items.

    //======== Toolbar specific methods:
    procedure TBAddBitmap( Bitmap: HBitmap );
    {* |<#toolbar>
       Adds bitmaps to a toolbar. You can pass special values as Bitmap to
       add one of predefined system button images bitmaps:
       |<br> THandle(-1) to add standard small icons,
       |<br> THandle(-2) to add standard large icons,
       |<br> THandle(-5) to add standard small view icons,
       |<br> THandle(-6) to add standard large view icons,
       |<br> THandle(-9) to add standard small view icons,
       |<br> THandle(-10) to add standard large view icons,
       (in that case use following values as indexes to the standard and view
       bitmaps:
       |<br>
       STD_COPY, STD_CUT, STD_DELETE, STD_FILENEW, STD_FILEOPEN, STD_FILESAVE,
       STD_FIND, STD_HELP, STD_PASTE, STD_PRINT, STD_PRINTPRE, STD_PROPERTIES,
       STD_REDO, STD_REPLACE, STD_UNDO,
       |<br>
       VIEW_LARGEICONS, VIEW_SMALLICONS,
       VIEW_LIST, VIEW_DETAILS, VIEW_SORTNAME, VIEW_SORTSIZE, VIEW_SORTDATE,
       VIEW_SORTTYPE (use it as parameters BtnImgIdxArray in TBAddButtons or
       TBInsertButtons methods, and in assigning value to TBButtonImage[ ]
       property).
       Added bitmaps have indeces starting from previous count of images
       (as these are appended to existing - if any).
       |<br>
       Note, that if You add your own (custom) bitmap, it is not transparent.
       Do not assume that clSilver is always equal to clBtnFace. Use API
       function CreateMappedBitmap to load bitmap from resource and map
       desired colors as you wish (e.g., convert clTeal to clBtnFace). Or,
       call defined in KOL function LoadMappedBitmap to do the same more easy.
       Unfortunately, resource identifier for bitmap to pass it to LoadMappedBitmap
       or to CreateMappedBitmap seems must be integer, so it is necessary to
       create rc-file manually and compile using Borland Resource Compiler to
       figure it out. }


    function TBAddButtons( const Buttons: array of PChar; const BtnImgIdxArray: array
              of Integer ): Integer;
    {* |<#toolbar>
       Adds buttons to toolbar. Last string in Buttons array *must* be empty
       ('' or nil), so to add buttons without text, pass ' ' string (one space
       char). It is not necessary to provide image indexes for all
       buttons (it is sufficient to assign index for first button only).
       But in place, correspondent to separator button (defined by string '-'),
       any integer must be passed to assign follow image indexes correctly.
       See example.
       |*Toolbar adding buttons sample.
       Code below shows how to call TBAddButtons method to add two buttons with
       a separator between these buttons. idxNew and idxOld are integer
       expressions assigning image indexes to buttons 'New' and 'Old'. This
       indexes are zero-based and refer to bitmap images, added earlier (either
       in creating toolbar by call of NewToolbar or later in call of TBAddBitmap).
       !
       !     TBAddButtons( [ '&New', '-', '&Old', '' ], [ idxNew, 0, idxOld ] );
       !
       |*
       To add check buttons, use prefix '+' or '-' in button definition
       string. If next character is '!', such buttons are grouped to a
       radio-group. Also, it is possible to use '^' prefix (must be first) to
       define button with small drop-down section (use also OnTBDropDown event
       to respond to clicking drop down section of such buttons).
       |<br>
       This function returns command id for first added button (other
       id's can be calculated incrementing the result by one for each
       button, except separators, which have no command id).
       |<br>
       Note: for static toolbar (single in application and created
       once) ids are started from value 100. }

    function TBInsertButtons( BeforeIdx: Integer; Buttons: array of PChar;
             BtnImgIdxArray: array of Integer ): Integer;
    {* |<#toolbar>
       Inserts buttons before button with given index on toolbar. Returns
       command identifier for first button inserted (other can be calculated
       incrementing returned value needed times. See also TBAddButtons. }

    procedure TBDeleteButton( BtnID: Integer );
    {* |<#toolbar>
       Deletes single button given by its command id. To delete separator,
       use TBDeleteBtnByIdx instead. }

    procedure TBDeleteBtnByIdx( Idx: Integer );
    {* |<#toolbar>
       Deletes single button given by its index in toolbar (not by command ID). }

    procedure TBAssignEvents( BtnID: Integer; Events: array of TOnToolbarButtonClick );
    {* |<#toolbar>
       Allows to assign separate OnClick events for every toolbar button.
       BtnID should be toolbar button ID or index of the first button to
       assign event. If it is an ID, events are assigned to buttons in
       creation order. Otherwise, events are assigned in placement order.
       Anyway, separator buttons are not skipped, so pass at least nil for such
       button as an event.
       |<br>
       Please note, that though not all buttons should exist before
       assigning events to it, therefore at least the first button
       (specified by BtnID) must be already added before calling TBAssignEvents. }

    procedure TBResetImgIdx( BtnID, BtnCount: Integer );
    {* |<#toolbar>
       Resets image index for BtnCount buttons starting from BtnID. }

    property CurItem: Integer read fCurItem;
    {* |<#toolbar>
       For toolbar, in OnClick event this property can be used to determine
       which button was clicked (100-based button id in toolbar). It is also
       possible to use CurIndex property (zero-based) for this purpose as
       well, but do not assume, that CurItem always equal to CurIndex+100.
       At least, it is possible to call TBItem2Index function to convert
       button ID to its index in toolbar.
       |<br>
       In case, when button (or toolbar itself) is clicked using right
       mouse button, CurItem and CurIndex are always set to -1. To further
       determine which button was clicked, get mouse coordinates on screen,
       apply Screen2Client method of toolbar control to it and then use
       TBButtonAtPos function to determine which button was under cursor.

       Following keys will be maintained additionally:
       |<pre>
       CTRL+I - switch "Italic",
       CTRL+B - switch "Bold",
       CTRL+U - switch "Underline",
       CTRL+SHIFT+U - swith underline type
                    and turn underline on (note, that some of underline styles
                    can not be shown properly in RichEdit v2.0 and lower,
                    though RichEdit2.0 stores data successfully).
       CTRL+O - switch "StrikeOut",
       CTRL+'gray+' - increase font size,

       CTRL+SHIFT+'gray-' - subscript.
       CTRL+SHIFT+Z - ReDo
       |</pre>
       And, though following standard formatting keys are provided by RichEdit
       control itself in Windows2000, some of these are not functioning
       automatically in earlier Windows versions, even for RichEdit2.0. So,
       functionality of some of these (marked with (*) ) are added here too:
       |<pre>
       CTRL+L - align paragraph left,           (*)
       CTRL+R - align paragraph right,          (*)
       CTRL+E - align paragraph center,         (*)
       CTRL+A - select all,                     (*)
       double-click on word - select word,
       CTRL+Right - to next word,
       CTRL+Left - to previous word,
       CTRL+Home - to the beginning of text,
       CTRL+End - to the end of text.
       CTRL+Z - UnDo
       |</pre>
       If You originally assign some (plain) text to Text property, switching "underline"
       can also change other font attributes, e.g., "bold" - if fsBold style is
       in default Font. To prevent such behavior, select entire text first (see
       SelectAll) and make assignment to RE_Font property, e.g.:
       !        RichEd1.SelectAll;
       !        RichEd1.RE_Font := RichEd1.RE_Font;
       !        RichEd1.SelLength := 0;
       |<br>
       And, some other notices about formatting. Please remember, that only True
       Type fonts can be succefully scaled and transformed to get desired effects
       (e.g., bold). By default, RichEdit uses System font face name, which can
       even have problems with fsBold style. Please remember also, that assigning
       RE_Font to RE_Font just initializying formatting attributes, making all
       those valid in entire text, but does not change font attributes. To use
       True Type font, directly assign face name You wish, e.g.:
       !        RichEd1.SelectAll;
       !        RichEd1.RE_Font := RichEd1.RE_Font;
       !        RichEd1.RE_Font.FontName := 'Arial';

    property RE_OverwriteMode: Boolean read REGetOverwite write RESetOverwrite;
    {* |<#richedit>
       This property allows to control insert/overwrite mode. First, to examine, if
       insert or overwrite mode is current (but it is necessary either to
       access this property, at least once, immediately after creating RichEdit
       control, or to assign event OnRE_InsOvrMode_Change to your handler).
       Second, to set desired mode programmatically - by assigning value to
       this property (You also have to initialize monitoring procedure by either
       reading RE_OverwriteMode property or assigning handler to event
       OnRE_InsOvrMode_Change immediately following RichEdit control creation). }
    property OnRE_InsOvrMode_Change: TOnEvent read fOnREInsModeChg write fOnREInsModeChg;
    {* |<#richedit>
       This event is called, whenever key INSERT is pressed in control (and for
       RichEdit, this means, that insert mode is changed). }
    property RE_DisableOverwriteChange: Boolean read fReOvrDisable write RESetOvrDisable;
    {* |<#richedit>
       It is possible to disable switching between "insert" and "overwrite" mode
       by user (therefore, event OnRE_InsOvrMode_Change continue works, but it
       just called when key INSERT is pressed, though RE_OverwriteMode property
       is not actually changed if switching is disabled). }

       flag.
       |<br>&nbsp;&nbsp;&nbsp;
       If You want to provide progress (e.g. in form of progress bar), assign
       OnProgress event to your handler - and to examine current position of
       loading, read TSream.Position property of soiurce stream). }
    function RE_SaveToStream( Stream: PStream; Format: TRETextFormat; SelectionOnly: Boolean ): Boolean;
    {* |<#richedit>
       Use this method rather then RE_TextProperty to store data to file

       end of RichEdit data). If SelectionOnly flag is True, only selected
       part of RichEdit text is saved.
       |<br>&nbsp;&nbsp;&nbsp;
       Like for RE_LoadFromStream, it is possible to assign your method to
       OnProgress event (but to calculate progress of save-to-stream operation,
       compare current stream position with RE_Size[ rsBytes ] property
       value). }

    property OnProgress: TOnEvent read fOnProgress write fOnProgress;
    {* |<#richedit>
       This event is called during RE_SaveToStream, RE_LoadFromStream (and also
       during RE_SaveToFile, RE_LoadFromFile and while accessing or changing
       RE_Text property). To calculate relative progress, it is possible to
       examine current position in stream/file with its total size while reading,
       or with rich edit text size, while writing (property RE_TextSize[ rsBytes ]).

//[NewForm DECLARATION]

{* |<#control>
   Creates form window object and returns pointer to it. If You use only one form,
   and You are not going to do applet button on task bar invisible, it is not
   necessary to create also special applet button window - just pass
   your (main) form object to Run procedure. In that case, it is a good
   idea to assign pointer to your main form object to Applet variable
   immediately following creating it - because some objects (e.g. TTimer)
   want to have Applet assigned to something.
   |<br>
   |&D=<a href="tcontrol.htm#%1" target=_top> %0 </a>
   Following methods, properties and events are useful to work with forms
   (ones common for all visual objects, such as <D Left>, <D Top>, <D Width>,
   <D Height>, etc. are not listed here - look TControl for it):
   |#form }

//[_NewControl DECLARATION]

//[NewButton DECLARATION]
function NewButton( AParent: PControl; const Caption: String ): PControl;
{* |<#control>
   Creates button on given parent control or form.
   Please note, that in Windows, buttons can not change its <D Font> color
   and to be <D Transparent>.
   |<br> Following methods, properies and events are (especially) useful with
   a button:
   |#button }

//[NewBitBtn DECLARATION]
function NewBitBtn( AParent: PControl; const Caption: String;
         Options: TBitBtnOptions; Layout: TGlyphLayout; GlyphBitmap: HBitmap; GlyphCount: Integer ): PControl;
{* |<#control>
   Creates image button (actually implemented as owner-drawn). In Options,
   it is possible to determine, whether bitmap or image list used to contain
   one or more (up to 5) images, correspondent to certain BitBtn state.
   |<br>&nbsp;&nbsp;&nbsp;
   For case of imagelist (option bboImageList), it is possible to use a
   number of glyphs from the image list, starting from image index given
   by GlyphCount parameter. Number of used glyphs is passed in that case
   in high word of GlyphCount parameter (if 0, one image is used therefore).
   For bboImageList, BitBtn can be Transparent (and in that case bboNoBorder
   style can be useful to draw custom buttons of non-rectangular shape).
   |<br>&nbsp;&nbsp;&nbsp;
   For case of bitmap BitBtn, image is stretched down (if too big), but can
   not be transparent. It is not necessary for bitmap BitBtn to pass correct
   GlyphCount - it is calculated on base of bitmap size, if 0 is passed.
   |<br>&nbsp;&nbsp;&nbsp;
   And, certainly, BitBtn can be without glyph image (text only). For that
   case, it is therefore is more flexible and power than usual Button (but
   requires more code). E.g., BitBtn can change its <D Font>, <D Color>,
   and to be totally <D Transparent>.
   Moreover, BitBtn can be <D Flat>, bboFixed, <D SpeedButton> and
   have property <D RepeatInterval>.
   |<br>&nbsp;&nbsp;&nbsp;
   Note: if You use bboFixed Style, use OnChange event instead of OnClick,
   because <D Checked> state is changed immediately however OnClick occure
   only when mouse or space key released (and can be not called at all if
   mouse button is released out of BitBtn bounds). Also, bboFixed defines
   only which glyph to show (the border if it is not turned off behaves as
   usual for a button, i.e. it becomes lowered and then raised again at any click).
   Here You can find references to other properties, events and methods
   applicable to BitBtn:
   |#bitbtn }

//[NewLabel DECLARATION]
function NewLabel( AParent: PControl; const Caption: String ): PControl;
{* |<#control>
   Creates static text control (native Windows STATIC control).
   Use property <D Caption> at run time to change label text. Also
   it is possible to adjust label <D Font>, <D Brush> or <D Color>.
   Label can be <D Transparent>. If You want to have rotated text
   label, call NewLabelEffect instead and change its <D Font>.FontOrientation.
   Other references certain for a label:
   |#label }

//[NewWordWrapLabel DECLARATION]
function NewWordWrapLabel( AParent: PControl; const Caption: String ): PControl;
{* |<#control>

   See also:
   |#wwlabel
   |#label }

//[NewLabelEffect DECLARATION]
function NewLabelEffect( AParent: PControl; const Caption: String; ShadowDeep: Integer ): PControl;
{* |<#control>
   Creates 3D-label with capability to rotate its text <D Caption>, which
   is controlled by changing <D Font>.FontOrientation property. If You want
   to get flat effect label (e.g. to rotate it only), pass <D ShadowDeep> = 0.
   Please note, that drawing procedure uses <D Canvas> property, so using of
   LabelEffect leads to increase size of executable.

//[NewImageShow DECLARATION]
function NewImageShow( AParent: PControl; AImgList: PImageList; ImgIdx: Integer ): PControl;
{* |<#control>
   Creates an image show control, implemented as a paintbox which is used to
   draw an image from the imagelist. At run-time, use property CurIndex to
   select another image from the imagelist, and a property ImageListNormal to
   use another image list. When the control is created, its size becomes
   equal to dimensions of imagelist (if any). }

   certain large image. To provide automatic scrolling of a set of child controls,
   use advanced scroll box, created with NewScrollBoxEx. }

procedure NotifyScrollBox( Self_, Child: PControl );


function NewScrollBoxEx( AParent: PControl; EdgeStyle: TEdgeStyle ): PControl;
{* |<#control>

   controls (if any). }

//[NewGradientPanel DECLARATION]
function NewGradientPanel( AParent: PControl; Color1, Color2: TColor ): PControl;
{* |<#control>
   Creates gradient-filled STATIC control. To adjust colors at the
   run time, change <D Color1> and <D Color2> properties (which initially are
   assigned from Color1, Color2 parameters), and call <D Invalidate> method
   to repaint control. }

function NewGradientPanelEx( AParent: PControl; Color1, Color2: TColor;
                             Style: TGradientStyle; Layout: TGradientLayout ): PControl;
{* |<#control>
   Creates gradient-filled STATIC control. To adjust colors at the
   run time, change <D Color1> and <D Color2> properties (which initially are
   assigned from Color1, Color2 parameters), and call <D Invalidate> method
   to repaint control. Depending on style and first line/point layout, can
   looking different. Idea: Vladimir Stojiljkovic. }

//[NewPanel DECLARATION]
function NewPanel( AParent: PControl; EdgeStyle: TEdgeStyle ): PControl;
{* |<#control>
   Creates panel, which can be parent for other controls (though, any
   control can be used as a parent for other ones, but panel is specially
   designed for such purpose). }

//[NewMDIxxx DECLARATIONS]
function NewMDIClient( AParent: PControl; WindowMenu: THandle ): PControl;
{* |<#control>
   Creates MDI client window, which is a special type of child window,
   containing all MDI child windows, created calling NewMDIChild function.
   On a form, MDI client behaves like a panel, so it can be placed and sized
   (or aligned) like any other controls. To minimize flick during resizing
   main form having another aligned controls, place MDI client window on
   a panel and align it caClient in the panel.
   |<br>Note:
   MDI client must be a single on the form. }

function NewMDIChild( AParent: PControl; const ACaption: String ): PControl;
{* |<#control>
   Creates MDI client window. AParent should be a MDI client window,
   created with NewMDIClient function. }

//[NewSplitter DECLARATIONS]
function NewSplitter( AParent: PControl; MinSizePrev, MinSizeNext: Integer ): PControl;
{* |<#control>
   Creates splitter control, which will separate previous one (i.e. last
   created one before splitter on the same parent) from created
   next, allowing to user to adjust size of separated controls by dragging
   the splitter in desired direction. Created splitter becomes vertical
   or horizontal depending on Align style of previous control on the same
   parent (if caLeft/caRight then vertical, if caTop/caBottom then horizontal).
   |<br>&nbsp;&nbsp;&nbsp;
   Please note, what if previous control has no Align equal to caLeft/caRight
   or caTop/caBottom, splitter will not be able to function normally. If
   previous control does not exist, it is yet possible to use splitter as
   a resizeable panel (but set its initial Align value first - otherwise it
   is not set by default. Also, change Cursor property as You wish in that
   case, since it is not set too in case, when previous control does not
   exist).
   |<br>&nbsp;&nbsp;&nbsp;
   Additional parameters determine, which minimal size (width or height -
   correspondently to split direction) is allowed for left (top) control
   and to rest of client area of parent, correspondently. (It is possible
   later to set second control for checking its size with MinSizeNext
   value - using TControl.SecondControl property). If -1 passed,
   correspondent control size is not checked during dragging of splitter.
   Usually 0 is more suitable value (with this value, it is garantee, that
   splitter will be always available even if mouse was released far from the
   edge of form).
   |<br>&nbsp;&nbsp;&nbsp;
   It is possible for user to press Escape any time while dragging splitter
   to abort all adjustments made starting from left mouse button push and
   begin of drag the splitter. But remember please, that such event is
   controlled using timer, and therefore correspondent keyboard events
   are received by currently focused control. Be sure, that pressing Escape
   will not affect to any control on form, which could be focused, otherwise
   filter keyboard messages (by yourself) to prevent undesired handling of
   Escape key by certain controls while splitting. (Use Dragging property
   to check if splitter is dragging by user with mouse).

   to determine if a splitter will be beveled or not. See also NewSplitter. }

//[NewGroupbox DECLARATION]
function NewGroupbox( AParent: PControl; const Caption: String ): PControl;

//[NewEditbox DECLARATION]
function NewEditbox( AParent: PControl; Options: TEditOptions ): PControl;
{* |<#control>
   Creates edit box control. To create multiline edit box, similar to
   TMemo in VCL, apply eoMultiline in Options. Following properties, methods,
   events are special for edit controls:
   |#edit }

//[NewRichEdit DECLARATION]
function NewRichEdit( AParent: PControl; Options: TEditOptions ): PControl;
{* |<#control>
   Creates rich text edit control. A rich edit control is a window in which
   the user can enter and edit text. The text can be assigned character and
   paragraph formatting, and can include embedded OLE objects. Rich edit
   controls provide a programming interface for formatting text. However, an
   application must implement any user interface components necessary to make
   formatting operations available to the user.
   |<br>&nbsp;&nbsp;&nbsp;
   Note: eoPassword, eoMultiline options have no effect for RichEdit control.
   Some operations are supersided with special versions of those, created
   especially for RichEdit, but in some cases it is necessary to use
   another properties and methods, specially designed for RichEdit (see
   methods and properties, which names are starting from RE_...).
   |<br>&nbsp;&nbsp;&nbsp;
   Following properties, methods, events are special for edit controls:
   |#richedit
   }

function NewRichEdit1( AParent: PControl; Options: TEditOptions ): PControl;
{* |<#control>
   Like NewRichEdit, but to work with older RichEdit control version 1.0
   (window class 'RichEdit' forced to use instead of 'RichEdit20A', even
   if library RICHED20.DLL found and loaded successfully). One more
   difference - OleInit is not called, so the most of OLE capabilities
   of RichEdit could not working. }

//[NewListbox DECLARATION]
function NewListbox( AParent: PControl; Options: TListOptions ): PControl;

   |#listbox }

//[NewCombobox DECLARATION]
function NewCombobox( AParent: PControl; Options: TComboOptions ): PControl;

   Creates new combo box control. Note, that it is not possible to align
   combobox caLeft or caRight: this can cause infinit recursion in the
   application.
   |<br>Following properties, methods and events are
   special for Combobox:

   progress bar:
   |#progressbar
   See also NewProgressEx. }

function NewProgressbarEx( AParent: PControl; Options: TProgressbarOptions ): PControl;
{* |<#control>
   Can create progress bar with smooth style (progress is not segmented
   onto bricks) or/and vertical progress bar - using additional parameter.
   For list of properties, suitable for progress bars, see NewProgressbar. }

//[NewListVew DECLARATION]
function NewListView( AParent: PControl; Style: TListViewStyle; Options: TListViewOptions;
  ImageListSmall, ImageListNormal, ImageListState: PImageList ): PControl;
{* |<#control>
   Creates list view control. It is very powerful control, which can partially
   compensate absence of grid controls (in lvsDetail view mode). Properties,
   methods and events, special for list view control are:
   |#listview }

//[NewTreeView DECLARATION]
function NewTreeView( AParent: PControl; Options: TTreeViewOptions;
                      ImgListNormal, ImgListState: PImageList ): PControl;
{* |<#control>
   Creates tree view control. See tree view methods and properties:
   |#treeview }

//[NewTabControl DECLARATION]
function NewTabControl( AParent: PControl; Tabs: array of String; Options: TTabControlOptions;
         ImgList: PImageList; ImgList1stIdx: Integer ): PControl;
{* |<#control>
   Creates new tab control (like notebook). To place child control on a certain
   page of TabControl, use property Pages[ Idx ], for example:
   ! Label1 := NewLabel( TabControl1.Pages[ 0 ], 'Label1' );
   | &nbsp;&nbsp;&nbsp;
   To determine number of pages at run time, use property <D Count>;
   |<br> to determine which page is currently selected (or to change
   selection), use property <D CurrentIndex>;
   |<br> to feedback to switch between tabs assign your handler to OnSelChange
   event;
   |<br>Note, that by default, tab control is created with a border lowered to
   tab control's parent. To remove it, you can apply WS_EX_TRANSPARENT extended
   style (see TControl.ExStyle property), but painting of some child controls
   can be strange a bit in this case (no border drawing for edit controls was
   found, but not always...). You can also apply style WS_THICKFRAME (TControl.Style
   property) to make the border raised.
   |<br> Other methods and properties, suitable for tab control, are:
   |#tabcontrol }

//[NewToolbar DECLARATION]
function NewToolbar( AParent: PControl; Align: TControlAlign; Options: TToolbarOptions;
                     Bitmap: HBitmap; Buttons: array of PChar;
                     BtnImgIdxArray: array of Integer ) : PControl;
{* |<#control>
   Creates toolbar control. Bitmap must contain images for all buttons
   excluding separators (defined by string '-' in Buttons array), otherwise
   last buttons will no have images at all. Image width for every button
   is assumed to be equal to Bitmap height (if last of "squares" has
   insufficient width, it will not be used). To define fixed buttons, use
   characters '+' or '-' as a prefix for button string (even empty). To
   create groups of (radio-)buttons, use also '!' follow '+' or '-'. (These rules
   are similar used in menu creation). To define drop down button, use (as
   first) prefix '^'. (Do not forget to set <D OnTBDropDown> event for this
   case). If You want to assign images to buttons not in the same order
   how these are placed in Bitmap (or You use system bitmap), define for every
   button (in BtnImgIdxArray array) indexes for every button (excluding
   separator buttons). Otherwise, it is possible to define index only for first
   button (e.g., [0]). It is also possible to change TBImages[ ] property
   for such purpose, or do the same in method TBSetBtnImgIdx).
   |<br>
   Following properties, methods and event are specially designed to work with
   toolbar control:
   |#toolbar
   |<br>&nbsp;&nbsp;&nbsp;
   If your project uses Align property to align controls, this can conflict with
   toolbar native aligning. To solve such problem, place toolbar to parent panel,
   which has its own Align property assigned to desired value.
   |<br>
   To create toolbar with buttons, drawn from top to bottom, instead from left
   to right, combine caLeft / caRight in Align parameter and style tboWrapable
   when create toolbar. To adjust width of vertically aligned toolbar, it is
   possible to call ResizeParentLeft for it. E.g.:

   ! P0 := NewPanel( W, esRaised ) .SetSize( 30, 0 ) .SetAlign( caLeft );
   ! //                            ^^^^^^^^^^^^^^^^^            //////
   !TB := NewToolbar( P0, caLeft, [ tboNoDivider, tboWrapable ], DWORD(-1),
   ! //                   //////                  ///////////
   !                  [ ' ', ' ', ' ', '-', ' ', ' ' ],
   !      [ STD_FILEOPEN ] ).ResizeParentRight;
   !//Note, that caLeft is *must*, and tboWrapable style too. SetSize for
   !//parent panel is not necessary, but only if ResizeParentRight is called
   !//than for Toolbar.
   |<br><br>
   One more note: if You create toolbar without text labels (passing ' ' for
   each button You add), include also option tboTextRight to fix incorrect
   sizing of buttons under Windows9x.

     <br>
     There is a known bug exist with similar invisible tray-iconized applications.
     When a menu is activated in response to tray mouse event, if there was
     not active window, belonging to the application, the menu is not disappeared
     when mouse is clicked anywhere else. This bug is occure in Windows9x/ME.
     To avoid it, activate first your form window. This last window shoud have
     status visible (but, certainly, there are no needs to place it on visible
     part of screen - change its position, so it will not be visible for user,
     if You wish).
     <br>
     Also, to make your application "invisible" but until special event is occure,
     use Applet separate from the main form, and make for both Visible := False.
     This allows for You to make your form visible any time You wish, and without
     making application button visible if You do not wish.

  <R Data sorting (quicksort implementation)>
  This part contains implementation of 'quick sort' algorithm,
   based on following code:

|<pre>
| TQSort by Mike Junkin 10/19/95.
| DoQSort routine adapted from Peter Szymiczek's QSort procedure which
| was presented in issue#8 of The Unofficial Delphi Newsletter.

| TQSort changed by Vladimir Kladov (Mr.Bonanzas) to allow 32-bit
| sorting (of big arrays with more than 64K elements).
|</pre>

  Finally, this sort procedure is adapted to XCL (and then to KOL)
  requirements (no references to SysUtils, Classes etc. TQSort object
  is transferred to a single procedure call and DoQSort method is
  renamed to SortData - which is a regular procedure now). }

//[Sorting TYPES]
type
  TCompareEvent = function (const Data: Pointer; const e1,e2 : Dword) : Integer;
  {* Event type to define comparison function between two elements of an array.
     This event handler must return -1 or +1 (correspondently for cases e1<e2
     and e2>e2). Items are enumerated from 0 to uNElem. }
  TSwapEvent = procedure (const Data : Pointer; const e1,e2 : Dword);
  {* Event type to define swap procedure which is swapping two elements of an
     array. }

//[SortData FUNCTIONS DECLARATIONS]
procedure SortData( const Data: Pointer; const uNElem: Dword;
                    const CompareFun: TCompareEvent;
                    const SwapProc: TSwapEvent );
{* Call it to sort any array of data of any kind, passing total
   number of items in an array and two defined (regular) function
   and procedure to perform custom compare and swap operations.
   First procedure parameter is to pass it to callback function
   CompareFun and procedure SwapProc. Items are enumerated from
   0 to uNElem-1. }

procedure SortIntegerArray( var A : array of Integer );
{* procedure to sort array of integers. }

procedure SortDwordArray( var A : array of DWORD );
{* Procedure to sort array of unsigned 32-bit integers.

{* Menu constructor. First created menu becomes main menu of form (if AParent
   is a form). All other menus becomes popup (can be activated using Popup
   method). To provide dynamic replacing of main menu, create all popup
   menus as children of any other control, not form itself.
   When Menu is created, pass FirstCmd integer value to set it
   as ID of first menu item (all other ID's obtained by incrementing this value),
   and Template, which is an array of PChar (usually array of string constants),
   containing list of menu item identifiers and/or formatting characters.
|<br>&nbsp;&nbsp;&nbsp;
  FirstCmd value is assigned to first menu item created as its ID,
  all follow menu items are assigned to ID's obtained from FirstCmd incrementing
  it by 1. It is desirable to provide not intersected ranges of ID's for
  defferent menus in the applet.
|<br>&nbsp;&nbsp;&nbsp;
  Following formatting characters can be used in menu template strings:
|&L=<br><b>%1</b>
  <L &amp; (in identifier)> - to underline next character and use it as a shortcut character
           when possible;
  <L + (in front of identifier)> - to make item checked. If also
|<b>!</b> is used before <b>
  &
|</b> than radioitem is defined;
  <L - (in front of identifier)> - item not checked;
  <L - (separate)> - separator (between two items);
  <L ( (separate)> - start of submenu;
  <L ) (separate)> - end of submenu;
|<br>&nbsp;&nbsp;&nbsp;
  To get access to menu items, use constants 0, 1, etc. It is a good idea
  to create special enumerated type to index correspondent menu items
  using Ord( ) operator. Note in that case, that it is necessary only to
  define constants correspondent to identifiers (positions, correspondent
  to separators or submenu brackets are not identified by numbers).

   For example, it is possible to get know for foreground window,
   which of its child window has focus. This function does not work in old
   Windows 95 (returns Wnd in that case). But for Windows 98, Windows NT/2000
   this function works fine. To obtain focused child of the window,
   use GetFocusedWindow, which is independant from Windows version. }

function GetFocusedChild( Wnd: HWnd ): HWnd;

   to given window, including functional keys and navigation keys. To
   post special key to target window, place a combination of names of
   such key together with keys, which should be passed simultaneously,
   between square or figure brackets. For example, [Ctrl F1], [Alt Shift Home],
   [Ctrl E]. For letters and usual characters, it is not necessary to
   simulate pressing it with determining all Shift combinations and it is
   sufficient to pass characters as is. (E.g., not '[Shift 1]', but '!'). }

   function in a such case). You can freely pass nil in place of ProcID

   This part of the unit modified by Tim Slusher and Vladimir Kladov.

{* Set of utility methods to work with files
   and reqistry.
   When programming KOL, which is Windows API-oriented, You should
   avoid alien (for Windows) embedded Pascal files handling, and
   use API-calls which implemented very well. This set of functions
   is intended to make this easier.
   Also TDirList object implementation present here and some registry
   access functions, which allow to make code more elegant.

   of Delphi VCL date-time. E.g., TDateTime type is not based on 31-Dec-1899,

{* This part of the unit contains implementation of streams for KOL. Please note,
   that both stream types (file stream and memory stream) are incapsulated
   by a single object type TStream. To avoid including unnedeed code,
   use constructing functions NewReadFileStream and NewWriteFileStream
   to work with file streams, which do not require both types of operation. }

{* To create new type of stream, define your own methods, and in your
   constructing function, pass it to _NewStream function (through
   TStreamMethods record). In a field Custom, You can store a reference to
   your own data of any type (but do not forget to define correct releasing
   of such data in your fClose procedure). }
