Re: [gtkextra] Disabling middle mouse button paste in GtkSheet

[jgotts linuxsavvy com]

No effect.

I added:

gtk_signal_emit_stop_by_name(GTK_OBJECT(w), "button_press_event");

as the first thing in my callback.  It is doing *something*, because it
prevents the user from selecting cells or a region.  (I only want to put it in
the section of my handler that handles second mouse button events, but this was
suitable for testing).

I also still have no idea why gtk_sheet_set_active_cell() seems to swallow a
button press event going towards double or triple clicks.

Gtk+ signal handling is really rough around the edges.  It's *really* hard to
do anything beyond processing "clicked" events and the occasional select/
unselect_row.  (Like my attempt to hack around severe limitations in the
GtkCombo widget causing XFree86 4.x to crash.)  At least much harder than Motif
is...

Thanks for your help,
John
