// The #GtkAboutDialog offers a simple way to display information about
// a program like its logo, name, copyright, website and license. It is
// also possible to give credits to the authors, documenters, translators
// and artists who have worked on the program. An about dialog is typically
// opened when the user selects the <literal>About</literal> option from
// the <literal>Help</literal> menu. All parts of the dialog are optional.
// 
// About dialog often contain links and email addresses. #GtkAboutDialog
// supports this by offering global hooks, which are called when the user
// clicks on a link or email address, see gtk_about_dialog_set_email_hook()
// and gtk_about_dialog_set_url_hook(). Email addresses in the
// authors, documenters and artists properties are recognized by looking for
// <literal>&lt;user@<!-- -->host&gt;</literal>, URLs are
// recognized by looking for <literal>http://url</literal>, with
// <literal>url</literal> extending to the next space, tab or line break.
// 
// <para id="gtk-about-dialog-hook-setup">
// Since 2.18 #GtkAboutDialog provides default website and email hooks that
// use gtk_show_uri().
// </para>
// 
// If you want provide your own hooks overriding the default ones, it is
// important to do so before setting the website and email URL properties,
// like this:
// <informalexample><programlisting>
// gtk_about_dialog_set_url_hook (GTK_ABOUT_DIALOG (dialog), launch_url, NULL, NULL);
// gtk_about_dialog_set_website (GTK_ABOUT_DIALOG (dialog), app_url);
// </programlisting></informalexample>
// To disable the default hooks, you can pass %NULL as the hook func. Then,
// the #GtkAboutDialog widget will not display the website or the
// email addresses as clickable.
// 
// To make constructing a #GtkAboutDialog as convenient as possible, you can
// use the function gtk_show_about_dialog() which constructs and shows a dialog
// and keeps it around so that it can be shown again.
// 
// Note that GTK+ sets a default title of <literal>_("About &percnt;s")</literal>
// on the dialog window (where &percnt;s is replaced by the name of the
// application, but in order to ensure proper translation of the title,
// applications should set the title property explicitly when constructing
// a #GtkAboutDialog, as shown in the following example:
// <informalexample><programlisting>
// gtk_show_about_dialog (NULL,
// "program-name", "ExampleCode",
// "logo", example_logo,
// "title" _("About ExampleCode"),
// NULL);
// </programlisting></informalexample>
// Note that prior to GTK+ 2.12, the #GtkAboutDialog:program-name property
// was called "name". This was changed to avoid the conflict with the
// #GtkWidget:name property.

// The #GtkAccelLabel widget is a subclass of #GtkLabel that also displays an
// accelerator key on the right of the label text, e.g. 'Ctl+S'.
// It is commonly used in menus to show the keyboard short-cuts for commands.
// 
// The accelerator key to display is not set explicitly.
// Instead, the #GtkAccelLabel displays the accelerators which have been added to
// a particular widget. This widget is set by calling
// gtk_accel_label_set_accel_widget().
// 
// For example, a #GtkMenuItem widget may have an accelerator added to emit the
// "activate" signal when the 'Ctl+S' key combination is pressed.
// A #GtkAccelLabel is created and added to the #GtkMenuItem, and
// gtk_accel_label_set_accel_widget() is called with the #GtkMenuItem as the
// second argument. The #GtkAccelLabel will now display 'Ctl+S' after its label.
// 
// Note that creating a #GtkMenuItem with gtk_menu_item_new_with_label() (or
// one of the similar functions for #GtkCheckMenuItem and #GtkRadioMenuItem)
// automatically adds a #GtkAccelLabel to the #GtkMenuItem and calls
// gtk_accel_label_set_accel_widget() to set it up for you.
// 
// A #GtkAccelLabel will only display accelerators which have %GTK_ACCEL_VISIBLE
// set (see #GtkAccelFlags).
// A #GtkAccelLabel can display multiple accelerators and even signal names,
// though it is almost always used to display just one accelerator key.
// <example>
// <title>Creating a simple menu item with an accelerator key.</title>
// <programlisting>
// GtkWidget *save_item;
// GtkAccelGroup *accel_group;
// 
// /<!---->* Create a GtkAccelGroup and add it to the window. *<!---->/
// accel_group = gtk_accel_group_new (<!-- -->);

// save_item = gtk_menu_item_new_with_label ("Save");
// gtk_widget_show (save_item);
// gtk_container_add (GTK_CONTAINER (menu), save_item);
// 
// /<!---->* Now add the accelerator to the GtkMenuItem. Note that since we called

// GtkAccelLabel is automatically set up to display the GtkMenuItem
// accelerators. We just need to make sure we use GTK_ACCEL_VISIBLE here. *<!---->/

// A GtkComboBox is a widget that allows the user to choose from a list of
// valid choices. The GtkComboBox displays the selected choice. When
// activated, the GtkComboBox displays a popup which allows the user to
// make a new choice. The style in which the selected value is displayed,
// and the style of the popup is determined by the current theme. It may
// be similar to a Windows-style combo box.
// 
// The GtkComboBox uses the model-view pattern; the list of valid choices
// is specified in the form of a tree model, and the display of the choices
// can be adapted to the data in the model by using cell renderers, as you
// would in a tree view. This is possible since GtkComboBox implements the
// #GtkCellLayout interface. The tree model holding the valid choices is
// not restricted to a flat list, it can be a real tree, and the popup will
// reflect the tree structure.
// 
// To allow the user to enter values not in the model, the 'has-entry'
// property allows the GtkComboBox to contain a #GtkEntry. This entry
// can be accessed by calling gtk_bin_get_child() on the combo box.
// 
// For a simple list of textual choices, the model-view API of GtkComboBox
// can be a bit overwhelming. In this case, #GtkComboBoxText offers a
// simple alternative. Both GtkComboBox and #GtkComboBoxText can contain
// an entry.

// #GtkIMContext defines the interface for GTK+ input methods. An input method
// is used by GTK+ text input widgets like #GtkEntry to map from key events to
// Unicode character strings.
// 
// The user may change the current input method via a context menu, unless the   
// #GtkSettings:gtk-show-input-method-menu GtkSettings property is set to FALSE. 
// The default input method can be set programmatically via the 
// #GtkSettings:gtk-im-module GtkSettings property. Alternatively, you may set 
// the GTK_IM_MODULE environment variable as documented in #gtk-running.
// 
// The #GtkEntry #GtkEntry:im-module and #GtkTextView #GtkTextView:im-module 
// properties may also be used to set input methods for specific widget 
// instances. For instance, a certain entry widget might be expected to contain 
// certain characters which would be easier to input with a certain input 
// method.
// 
// An input method may consume multiple key events in sequence and finally
// output the composed result. This is called preediting, and an input method
// may provide feedback about this process by displaying the intermediate
// composition states as preedit text. For instance, the default GTK+ input
// method implements the input of arbitrary Unicode code points by holding down
// the Control and Shift keys and then typing "U" followed by the hexadecimal
// digits of the code point.  When releasing the Control and Shift keys,
// preediting ends and the character is inserted as text. Ctrl+Shift+u20AC for
// example results in the € sign.
// 
// Additional input methods can be made available for use by GTK+ widgets as
// loadable modules. An input method module is a small shared library which
// implements a subclass of #GtkIMContext or #GtkIMContextSimple and exports
// these four functions:
// 
// <informalexample><programlisting>
// void im_module_init(#GTypeModule *module);
// </programlisting></informalexample>
// This function should register the #GType of the #GtkIMContext subclass which
// implements the input method by means of g_type_module_register_type(). Note
// that g_type_register_static() cannot be used as the type needs to be
// registered dynamically.
// 
// <informalexample><programlisting>
// void im_module_exit(void);
// </programlisting></informalexample>
// Here goes any cleanup code your input method might require on module unload.
// 
// <informalexample><programlisting>
// void im_module_list(const #GtkIMContextInfo ***contexts, int *n_contexts)
// {
// *contexts = info_list;
// *n_contexts = G_N_ELEMENTS (info_list);
// }
// </programlisting></informalexample>
// This function returns the list of input methods provided by the module. The
// example implementation above shows a common solution and simply returns a
// pointer to statically defined array of #GtkIMContextInfo items for each
// provided input method.
// 
// <informalexample><programlisting>
// #GtkIMContext * im_module_create(const #gchar *context_id);
// </programlisting></informalexample>
// This function should return a pointer to a newly created instance of the
// #GtkIMContext subclass identified by @context_id. The context ID is the same
// as specified in the #GtkIMContextInfo array returned by im_module_list().
// 
// After a new loadable input method module has been installed on the system,
// the configuration file <filename>gtk.immodules</filename> needs to be
// regenerated by <link linkend="gtk-query-immodules-2.0">gtk-query-immodules-2.0</link>,

// <informalexample><programlisting>
// GtkWidget *image;
// image = gtk_image_new_from_file ("myfile.png");
// </programlisting></informalexample>
// If the file isn't loaded successfully, the image will contain a
// "broken image" icon similar to that used in many web browsers.
// If you want to handle errors in loading the file yourself,
// for example by displaying an error message, then load the image with
// gdk_pixbuf_new_from_file(), then create the #GtkImage with
// gtk_image_new_from_pixbuf().
// 
// The image file may contain an animation, if so the #GtkImage will
// display an animation (#GdkPixbufAnimation) instead of a static image.
// 
// #GtkImage is a subclass of #GtkMisc, which implies that you can
// align it (center, left, right) and add padding to it, using

// #GtkImage is a "no window" widget (has no #GdkWindow of its own),
// so by default does not receive events. If you want to receive events
// on the image, such as button clicks, place the image inside a

//

// }
// </programlisting>

// 
// When handling events on the event box, keep in mind that coordinates
// in the image may be different from event box coordinates due to
// the alignment and padding settings on the image (see #GtkMisc).
// The simplest way to solve this is to set the alignment to 0.0
// (left/top), and set the padding to zero. Then the origin of
// the image will be the same as the origin of the event box.
// 
// Sometimes an application will want to avoid depending on external data
// files, such as image files. GTK+ comes with a program to avoid this,
// called <application>gdk-pixbuf-csource</application>. This program
// allows you to convert an image into a C variable declaration, which
// can then be loaded into a #GdkPixbuf using

// #GtkInfoBar is a widget that can be used to show messages to
// the user without showing a dialog. It is often temporarily shown
// at the top or bottom of a document. In contrast to #GtkDialog, which
// has a horizontal action area at the bottom, #GtkInfoBar has a
// vertical action area at the side.
// 
// The API of #GtkInfoBar is very similar to #GtkDialog, allowing you
// to add buttons to the action area with gtk_info_bar_add_button() or
// gtk_info_bar_new_with_buttons(). The sensitivity of action widgets
// can be controlled with gtk_info_bar_set_response_sensitive().
// To add widgets to the main content area of a #GtkInfoBar, use
// gtk_info_bar_get_content_area() and add your widgets to the container.
// 
// Similar to #GtkMessageDialog, the contents of a #GtkInfoBar can by
// classified as error message, warning, informational message, etc,
// by using gtk_info_bar_set_message_type(). GTK+ uses the message type
// to determine the background color of the message area.
// 
// <example>
// <title>Simple GtkInfoBar usage.</title>
// <programlisting>
// /&ast; set up info bar &ast;/
// info_bar = gtk_info_bar_new ();
// gtk_widget_set_no_show_all (info_bar, TRUE);
// message_label = gtk_label_new ("");
// gtk_widget_show (message_label);
// content_area = gtk_info_bar_get_content_area (GTK_INFO_BAR (info_bar));
// gtk_container_add (GTK_CONTAINER (content_area), message_label);
// gtk_info_bar_add_button (GTK_INFO_BAR (info_bar),
// GTK_STOCK_OK, GTK_RESPONSE_OK);
// g_signal_connect (info_bar, "response",
// G_CALLBACK (gtk_widget_hide), NULL);
// gtk_table_attach (GTK_TABLE (table),

// that widget's window ID to the other process,
// which then creates a #GtkPlug with that window ID.
// Any widgets contained in the #GtkPlug then will appear
// inside the first application's window.
// 
// The socket's window ID is obtained by using
// gtk_socket_get_id(). Before using this function,
// the socket must have been realized, and for hence,
// have been added to its parent.
// 
// <example>
// <title>Obtaining the window ID of a socket.</title>
// <programlisting>
// GtkWidget *socket = gtk_socket_new (<!-- -->);
// gtk_widget_show (socket);
// gtk_container_add (GTK_CONTAINER (parent), socket);
// 
// /<!---->* The following call is only necessary if one of
// * the ancestors of the socket is not yet visible.
// *<!---->/
// gtk_widget_realize (socket);
// g_print ("The ID of the sockets window is %#x\n",
// gtk_socket_get_id (socket));
// </programlisting>
// </example>
// 
// Note that if you pass the window ID of the socket to another
// process that will create a plug in the socket, you
// must make sure that the socket widget is not destroyed
// until that plug is created. Violating this rule will
// cause unpredictable consequences, the most likely
// consequence being that the plug will appear as a
// separate toplevel window. You can check if the plug
// has been created by using gtk_socket_get_plug_window(). If
// it returns a non-%NULL value, then the plug has been
// successfully created inside of the socket.
// 
// When GTK+ is notified that the embedded window has been
// destroyed, then it will destroy the socket as well. You
// should always, therefore, be prepared for your sockets
// to be destroyed at any time when the main event loop
// is running. To prevent this from happening, you can
// connect to the #GtkSocket::plug-removed signal.
// 
// The communication between a #GtkSocket and a #GtkPlug follows the
// <ulink url="http://www.freedesktop.org/Standards/xembed-spec">XEmbed</ulink>
// protocol. This protocol has also been implemented in other toolkits, e.g.
// <application>Qt</application>, allowing the same level of integration
// when embedding a <application>Qt</application> widget in GTK or vice versa.
// 
// A socket can also be used to swallow arbitrary
// pre-existing top-level windows using gtk_socket_steal(),
// though the integration when this is done will not be as close
// as between a #GtkPlug and a #GtkSocket.
