Hi,
I have included a small listing. The test program opens a panel and
show a bitmap.
What I want is to when the mouse is over the bitmap panel, I want to
trap the left mouse click.
The purpose is to get the position of the mouse pointer on the bitmap.
However, for some reason, the left (I also tried right) mouse clicks
are not intercepted.
I new to Python and wxWindows so any help would be greatly appreciated.
With kind regards,
Kris

I don't know much about wxPython, but
the left/right mouse button events _ARE_ trapped, but
not when clicking on the image, probably because they
are registered to the panel not to the image.
Just resize the window and click next to the image.
Hope this helps for now, before you get a response
from someone who knows some more about wxPython
(e.g. why the events from the bitmap are not forwarded
to the panel containing it?).
