Yes, you are. But the Layout will draw upon its parent window (or its closest ancestor with a window), so I presume you could draw on that. You may also be able to pack it inside a GtkEventBox, which *does* have a window, and draw on that.

It's not entirely trivial (you need to write a custom renderer, IIRC) and there may be some snags, but if you manage to cook one up, please let me know so I can add it to the FAQ.

Return True when you want to stop the event from being handled by the
widget. By default, it returns None, which is False, which is an
indication that the event was not handled.

[pygtk] How to stop a key_press_event in a TextView to prevent to write a space?
Hi!
I have the next function in a TextView. I'd like the TextView not to
write another space when there's another space around the cursor. The
problem is that I don't know how to break the key_press_event.
If it was possible to change the value of event.keyval to None or ''...
Thank you in advance!
Dàvik
def key_pressed(self, widget, event):
if event.keyval == gtk.gdk.keyval_from_name('space'): #If a
space has been pressedprint 'space pressed'
buffer = self.textview.get_buffer()
iter = buffer.get_iter_at_mark (buffer.get_insert())
next_char = iter.get_char() #Look the value of the next
characteriter.backward_char() #Move backwards in the iter
previous_char = iter.get_char() #Look the value of the
previous character
if next_char == ' ' or previous_char == ' ': # If the value
of one of both is a character... what should I do?what
should I do?else:
print 'no space pressed'
print event.keyval

Re: [pygtk] Get characters in a TextView
Hi, for have an iter at the current cursor position you can do: iter=buffer.get_iter_at_mark(buffer.get_insert()) at this point you use iter.get_char() for obtain the current char, then move the iter with iter.backward_char() and again iter.get_char() for check the previous char Best Regards!
