Thu Feb 12 23:59:49 1998 Owen Taylor <owt1@cornell.edu> * gtk/gtksignal.[ch] gtk/gtkmain.[ch] gtk/gtkcontainer.[ch] gtk/gtkselection.[ch] gdk/gdk.[ch] gtktypeutils.h Replaced all _interp functions with _full functions. (_interp functions left in for compatibility until 0.99.5). Difference: _full functions take _both_ a C-language callback and a marshaller, and simply ignore the C-language callback if the marshaller is present. This allows the destroy notification to be used without marshalling. gtk_selection_add_handler[_full]() regularized to agree with other callbacks. Also, added gtk_input_add_full() to the header file. (gtk_input_add_interp() was never there) * gtk/gtkmain.[ch] gtk/gtkwidget.c: Idle functions are now prioritized. Added new function gtk_idle_add_priority to create an idle with a specified priority (default is zero) constants #defined - GTK_PRIORITY_[HIGH/INTERNAL/DEFAULT/LOW] (redraws, resizes run at GTK_PRIORITY_INTERNAL) * gtk/gtkentry.c gtk/testselection.c: changes to keep up with change to gtkselection.c.
