Re: GtkDrawingArea weirdness ...

[Owen Taylor <otaylor redhat com>]

The set of events set on any widget is the union of:

 events set with gtk_widget_set_events()
 events the widget requests itself.

The DrawingArea asks for EXPOSE itself, so that will
always be set.

If that offends you, you could attach to "realize"
and use gdk_window_set_events (widget->window, ...)
to set a completely different event mask.

I'd just disconnect my signal handler for "expose_event".

Hope this explains things,
                                        Owen

[ 
  Why does GtkDrawingArea ask for EXPOSE. Because I got
  tired of telling people to add EXPOSE with 
  gtk_widget_set_events(), and because I considered
  it to be very rare that you would want a drawing
  and not want to handle exposes.
