Aha! Parenting the control to a DrawingArea was the step I was missing.
26+
Thanks!
27+
28+
I've now got this working, and an example application (a poor man's webbrowser,
29+
embedding IE in pygtk via AtlAxWin and ctypes) is below. There are a few things
30+
I couldn't make work:
31+
32+
o My keyboard accelerator (Alt+A to focus the address box) doesn't work
33+
when IE has the focus. Any ideas? How do pygtk accelerators work under the
34+
surface?
35+
36+
o Clicking a Gtk control when the IE control has the focus doesn't focus
37+
the Gtk control. I worked around this by putting an event handler on the
38+
Gtk controls for "button-press-event", but it would need to be done for
39+
every Gtk control - is there a better solution?
40+
41+
o IE's accelerator keys (eg. Tab and Alt+Left) don't work. In a pure Win32
42+
app, I'd fix this by calling IOleInPlaceActiveObject::TranslateAccelerator()
43+
in the message pump, but can I get access to the message pump in pygtk?
44+
45+
o Pressing Enter in the address box should have the same effect as pressing
46+
the Go button - I've done this, but it's a hack. Is there a better way?
47+
48+
o I'm using 65293 as the code for the Enter key - does pygtk have a constant
49+
for this?
50+
51+
This is my first pygtk program, so any criticism or suggestions will be
52+
gratefully received!
