  10 '\" The definitions below are for supplemental macros used in Tcl/Tk
  11 '\" manual entries.
  12 '\"
  13 '\" .AP type name in/out ?indent?
  14 '\"     Start paragraph describing an argument to a library procedure.
  15 '\"     type is type of argument (int, etc.), in/out is either "in", "out",
  16 '\"     or "in/out" to describe whether procedure reads or modifies arg,
  17 '\"     and indent is equivalent to second arg of .IP (shouldn't ever be
  18 '\"     needed;  use .AS below instead)
  19 '\"
  20 '\" .AS ?type? ?name?
  21 '\"     Give maximum sizes of arguments for setting tab stops.  Type and
  22 '\"     name are examples of largest possible arguments that will be passed
  23 '\"     to .AP later.  If args are omitted, default tab stops are used.
  24 '\"
  25 '\" .BS
  26 '\"     Start box enclosure.  From here until next .BE, everything will be
  27 '\"     enclosed in one large box.
  28 '\"
  29 '\" .BE
  30 '\"     End of box enclosure.
  31 '\"
  32 '\" .CS
  33 '\"     Begin code excerpt.
  34 '\"
  35 '\" .CE
  36 '\"     End code excerpt.
  37 '\"
  38 '\" .VS ?version? ?br?
  39 '\"     Begin vertical sidebar, for use in marking newly-changed parts
  40 '\"     of man pages.  The first argument is ignored and used for recording
  41 '\"     the version when the .VS was added, so that the sidebars can be
  42 '\"     found and removed when they reach a certain age.  If another argument
  43 '\"     is present, then a line break is forced before starting the sidebar.
  44 '\"
  45 '\" .VE
  46 '\"     End of vertical sidebar.
  47 '\"
  48 '\" .DS
  49 '\"     Begin an indented unfilled display.
  50 '\"
  51 '\" .DE
  52 '\"     End of indented unfilled display.
  53 '\"
  54 '\" .SO
  55 '\"     Start of list of standard options for a Tk widget.  The
  56 '\"     options follow on successive lines, in four columns separated
  57 '\"     by tabs.
  58 '\"
  59 '\" .SE
  60 '\"     End of list of standard options for a Tk widget.
  61 '\"
  62 '\" .OP cmdName dbName dbClass
  63 '\"     Start of description of a specific option.  cmdName gives the
  64 '\"     option's name as specified in the class command, dbName gives
  65 '\"     the option's name in the option database, and dbClass gives
  66 '\"     the option's class in the option database.
  67 '\"
  68 '\" .UL arg1 arg2
  69 '\"     Print arg1 underlined, then print arg2 normally.

 249 .SH NAME
 250 tkvars \- Variables used or set by Tk
 251 .BE
 252
 253 .SH DESCRIPTION
 254 .PP
 255 The following Tcl variables are either set or used by Tk at various times
 256 in its execution:
 257 .TP 15
 258 \fBtk_library\fR
 259 This variable holds the file name for a directory containing a library
 260 of Tcl scripts related to Tk.  These scripts include an initialization
 261 file that is normally processed whenever a Tk application starts up,
 262 plus other files containing procedures that implement default behaviors
 263 for widgets.
 264 The initial value of \fBtcl_library\fR is set when Tk is added to
 265 an interpreter;  this is done by searching several different directories
 266 until one is found that contains an appropriate Tk startup script.
 267 If the \fBTK_LIBRARY\fR environment variable exists, then
 268 the directory it names is checked first.
 269 If \fBTK_LIBRARY\fR isn't set or doesn't refer to an appropriate
 270 directory, then Tk checks several other directories based on a
 271 compiled-in default location, the location of the Tcl library directory,
 272 the location of the binary containing the application, and the current
 273 working directory.
 274 The variable can be modified by an application to switch to a different
 275 library.
 276 .TP
 277 \fBtk_patchLevel\fR
 278 Contains a decimal integer giving the current patch level for Tk.
 279 The patch level is incremented for each new release or patch, and
 280 it uniquely identifies an official version of Tk.
 281 .TP
 282 \fBtkPriv\fR
 283 This variable is an array containing several pieces of information
 284 that are private to Tk.  The elements of \fBtkPriv\fR are used by
 285 Tk library procedures and default bindings.
 286 They should not be accessed by any code outside Tk.
 287 .TP
 288 \fBtk_strictMotif\fR
 289 This variable is set to zero by default.
 290 If an application sets it to one, then Tk attempts to adhere as
 291 closely as possible to Motif look-and-feel standards.
 292 For example, active elements such as buttons and scrollbar
 293 sliders will not change color when the pointer passes over them.
 294 .TP 15
 295 \fBtk_version\fR
 296 Tk sets this variable in the interpreter for each application.
 297 The variable holds the current version number of the Tk
 298 library in the form \fImajor\fR.\fIminor\fR.  \fIMajor\fR and
 299 \fIminor\fR are integers.  The major version number increases in
 300 any Tk release that includes changes that are not backward compatible
 301 (i.e. whenever existing Tk applications and scripts may have to change to
 302 work with the new release).  The minor version number increases with
 303 each new release of Tk, except that it resets to zero whenever the
 304 major version number changes.
