Add a drag_data_received handler for the label.
Tue Jan 12 18:30:51 1999 Owen Taylor <otaylor@redhat.com>
* gtk/testdnd.c (label_drag_data_received): Add
a drag_data_received handler for the label.
Tue Jan 12 15:01:50 1999 Owen Taylor <otaylor@redhat.com>
* gdk/gdkevents.c: Removed the putback_events queue,
since it was causing problems with event ordering -
just keep a single queue. If we need it, we can
add priorities to events.
* gdk/gdkevents.c: Annotate events with flags - we allocate
a GdkEventPrivate structure in gdk_event_new() and use these
flags to mark an event being translated as "pending" -
I.e., not yet ready to be dequeued. So we can put
the event on the queue and get the order of the
events right. (This solves the double-click problems)
* gdk/gdk.h gdk/gdkevents.h: Add gdk_event_peek() to get a copy
of the next event on the event queue.
* gtk/gtkmain.c (gtk_main_do_event): Use gdk_event_peek()
to check the next event without causing event queue
reordering.
