Hack scrollwheel support into the eventloop, by treating button 4-5
Wed Jan 27 18:40:50 1999 Owen Taylor <otaylor@redhat.com>
* gtk/gtkmain.c (gtk_main_do_event): Hack scrollwheel
support into the eventloop, by treating button 4-5
presses on scrolled windows and scrollbars specially.
Put it here to keep the ugliness small and confined.
(We need to intercept the normal propagation in any case
to have this work reliably right now, since some
subwidgets will trap the button presses)
* gtk/gtkviewport.c (gtk_viewport_realize): Select for
BUTTON_PRESS to support the above hack.
