* gtk_check_version:
* @required_major: the required major version.

*
* Checks that the GTK+ library in use is compatible with the
* given version. Generally you would pass in the constants
* #GTK_MAJOR_VERSION, #GTK_MINOR_VERSION, #GTK_MICRO_VERSION
* as the three arguments to this function; that produces
* a check that the library in use is compatible with
* the version of GTK+ the application or module was compiled
* against.
*
* Compatibility is defined by two things: first the version
* of the running library is newer than the version
* @required_major.required_minor.@required_micro. Second
* the running library must be binary compatible with the
* version @required_major.required_minor.@required_micro
* (same major version.)
*
* This function is primarily for GTK+ modules; the module
* can call this function to check that it wasn't loaded
* into an incompatible version of GTK+. However, such a
* a check isn't completely reliable, since the module may be
* linked against an old version of GTK+ and calling the
* old version of gtk_check_version(), but still get loaded
* into an application using a newer version of GTK+.
*
* Return value: %NULL if the GTK+ library is compatible with the
* given version, or a string describing the version mismatch.
* The returned string is owned by GTK+ and should not be modified
* or freed.

* normally begin in gtk_main_do_event(). Depending on the type of
* event, existence of modal dialogs, grabs, etc., the event may be

* calls gtk_widget_event() on each widget it decides to send the

* simply emits the "event" and possibly an event-specific signal on a
* widget. gtk_propagate_event() is a bit higher-level, and
* gtk_main_do_event() is the highest level.
*
* All that said, you most likely don't want to use any of these
* functions; synthesizing events is rarely needed. Consider asking on
* the mailing list for better ways to achieve your goals. For
* example, use gdk_window_invalidate_rect() or
