Hi Alan,
I found this snippet of code inside a GTK Theme Switcher written by "[EMAIL PROTECTED]".
It doesn't specifically send the event you want, but maybe its relevant enough to help you synthesize one that does.
Maybe Havoc, Muhri, and Tor could comment on whether this could be modified to help or not, since I really don't know. Looks like there is UNIX GDK code to do something in gdk_send_clientmessage_toall(), but none in the Win32 port as yet though.
void
send_refresh_signal(void)
{
GdkEventClient event;
event.type = GDK_CLIENT_EVENT;
event.send_event = TRUE;
event.window = NULL;
event.message_type = gdk_atom_intern("_GTK_READ_RCFILES", FALSE);
event.data_format = 8;
gdk_event_send_clientmessage_toall((GdkEvent *)&event);
}
Just trying to help,
Tim.

The answer is pretty much no; you have to keep a list.
Then sythesize an expose and send it with gtk_widget_event(), the
default implementaiton of the draw method on GtkWidget (in
gtk/gtkwidget.c) has an example.
