I am emulating a keyboard with gtk buttons. To entry some text into a
gtk.Entry, I first set the focus on the gtk.Entry and then I press the
buttons. Keypad input works as expected (the keypad character appears
into gtk.Entry), but gtk complains with the following two messages at
each button pressing.
(myprogram.py:21650): Gdk-CRITICAL **: gdk_drawable_get_display:
assertion `GDK_IS_DRAWABLE (drawable)' failed
(myprogram.py:21650): Gdk-CRITICAL **: gdk_keymap_get_for_display:
assertion `GDK_IS_DISPLAY (display)' failed
My code is the following.
This is the callback code for the button press event.
event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
event.keyval = ord(key_associated_with_pressed_button)
keypad_widget.get_toplevel().get_focus().emit("key_press_event",
event)
Last row suppose that the keypad input must be directed to any widget
having the focus in the same top level window. In my case, the widget is
a gtk.Entry.
Thanks in advance for any help.
