PopupTransientWindow problem

wxPython Users
1

Hi all,

I'm having a problem with wxPopupTransientWindow closing prematurely. In the
example I've provided below clicking on the open button opens a
wxPopupTransientWindow with 3 buttons in it. If I try to click buttons B or
C then the wxPopupTransientWindow disappears without the EVT_BUTTON handler
being run. If I click on button A first (The one with the focus, don't know
if that's relevant) then the handler runs and I can then click on any of the
buttons as often as I like without the window closing.

I'm running wxPython 24.24u on Python 2.3.2 on WinXP

Any thoughts? Should I submit this as a bug?

Cheers,

Rich

wxPopupTransientWindow will be dismissed if the window, or it's first child if it has one, loses the focus. If you need more than one child you're probably better off usign a wxPopupWindow directly and doing something else about the focus and/or clicking the mouse outside the window.

If I click on button A first (The one with the focus, don't know
if that's relevant) then the handler runs and I can then click on any of the
buttons as often as I like without the window closing.

This sounds like a bug...

I may have seen that in the 2.5 demo code, too. One of the examples -- a
popup listbox -- was commented out when I started working on it. I played
around with it, and was able to get the 'popup' part working, but I could
never get the listbox events to fire. It's still in there, commented out; if
we're looking at the same problem then you have a built-in test case :slight_smile:
