I still use wxPython2.2.2/MSW98/Python2.0.
Trying to use 2.3.1 I've some difficulties, if I recreate dialogs with a
grid inside.
I've menue for changing the display language (german/english/...), so I
.Destroy()
all the old windows
(splitter/tree,notebook/scrolledwindow/controls,grid(s))
and recreate them new.
That's running well with 2.2.2 but with 2.3.1 after several
menue-actions (10 or more)
the background greys and the controls and grids are crippled. I can
close my
program and call it again, than I don't need any trials it's bad from
the beginning,
also some other MSW-applications have the same "decorations" (I've to
reboot).
The result of my trials is that it must displayed a grid, than it
happens, but sure I'm not.
Thanks, Udo
Hi Udo,
This sounds exactly like windows resource problems to me.
Open up your resource meter from Programs->Accessories->System tools.
Check if you have any code that create objects (that contain GDI
resources like bitmaps, menus, controls, etc.) in a loop that
might not be freed.
Does wxPython HYBRID version report leaked objects when your program
closes?
Windows 9x and friends are really pathetic in this respect. If a
program crashes it's resources aren't necessarily released. Usually
takes a reboot to get all the resources back.

GDI-resource-display:
with wx2.2.2: it goes from 85% after 26 dialog-recreations to 80%
and after closing back to the value before calling
with wx2.3.1: from 85% after 13 recreations to 69% and the next makes
it grey, after closing it rests there, it rests at the
last respective value also with fewer count of trials
and a higher percentage.
Why with each recreation it's decreasing ?
In this case the recreation was done per setting the holders with
the reference to the new dialogelements, no extra .Destroy() before.

running: 3x assert ..\common\string.cpp(1944)
(3 notebookpages with a grid inside)
The closing-report, and what is to do ? The program was called fom
__main__, but it can be called too from a other one.
