Sat Sep 8 16:19:02 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkmain.c: Implement a search path for GTK+ modules. * configure.in gtk/gtkrc.c gtk/Makefile.am: Look for modules in gtk-2.0/<type>/major.minor.(micro-binary_age) rather than in gtk-2.0/major.minor.micro/<type>/. This works better for a search path for modules. * gtk+-2.0.pc.in gtk+-2.0-uninstalled.pc.in: Add gtk_binary_version variable holding major.minor.(micro-binary_age). * modules/input/Makefile.am (moduledir): Fix installation directory to match change in lookup location. * gtk/gtkmain.c (gtk_init_check): Remove OS/2 code for dll suffixes. Needs to be handled in g_module_build_path(). * gtk/gtkrc.c gtk/queryimmodules.c: Use g_build_filename() where appropriate.

|
|
* normally begin in gtk_main_do_event(). Depending on the type of

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

* event to. So gtk_widget_event() is the lowest-level function; it
|
|
* simply emits the "event" and possibly an event-specific signal on a

* widget. gtk_propagate_event() is a bit higher-level, and

* 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
|
|
* gtk_widget_queue_draw() instead of making up expose events.
