Hi,
for a wxSlider I would like to attach events for
a) dragging the slider
b) releasing the slider
where a) just updates something quickly and after releasing
the slider b) should do a refined update (i.e. a slightly
longer computation).
I tried the code attached below, but I can't get b), i.e.
EVT_SCROLL_THUMBRELEASE, working.
Presumably I am missing something simple here - any advice
is very much appreciated.
Many thanks,
Arnd
P.S.: wxPython.__version__: '2.4.2.0p'
on debian linux, python 2.3
