wxListCtrl refresh problem

wxPython Dev
1

Hi,

Since 2.5.1.5 and 2.5.2.7 under Windows, there is a refresh problem on wxListCtrl.
The wxListCtrl is not refresh all the time, when I change application, and I come back on
my wxPython application. A part of this window or all the window is not repainted.
I saw the same bug in the demo.

Thanks

Windows 98, 2000, XP (and maybe all the Windows ...)
I don't test on Windows Me, but I think that this problem must be the same.
I haven't this bug on Linux, and MacOS. The same code with wxPython 2.4.x
works fine.

I'm _not_ seeing it under windows XP, Python 2.3.2, wxPython 2.5.1.5u. Covering then exposing the wxListCtrl in the demo seems to work fine.

I am not seeing it using Python 2.3.4, wx 2.5.2 on win XP. I'll try
it out on my 2K rig at home tonight.

Does anybody else see this problem using the demo?

I do not see the problem on W2K or WIN98SE running Python 2.3.4 and wxPython
2.5.2.7

Can the problem be reproduced with the demo in Safe Mode ?

Is the demo using the "Original" as the active version ? (Nice feature of
the wxPython demo on the "Demo Code" tab.)

no bug in demo (2.5.2.7), my last test shown this bug on 2.5.1.5.
I tried to reduce my code without sucess. The same code work fine
with 2.4.x.

On my application, the bug is visible when the wxListCtrl keeps the focus.
To see the bug, I proceed like this:
set the focus on wxListCtrl
change application
come back on wxPython application

with this lines, I avoid the bug:

.....
self.list.Bind(wx.EVT_SET_FOCUS, self.OnFocus) # only windows platforms
.....
def OnFocus(self, evt):
wx.CallAfter(self.Refresh)
evt.Skip()
