Hi all,
while trying to work around the problem mentioned in http://lists.wxwidgets.org/pipermail/wxpython-users/2009-February/084143.html
I noticed, that I can't find any suitable event to detect the
scrolling of a text widget on linux, Kubuntu,
I hoped a bit, that even if this object doesn't emit scrollwin events
on linux, it would be possible to catch other events instead - like
mouse motion, mouse buttons etc.
Unfortunately, it seems, that all this events only work in the actual
text field, not on scrollbars, even EVT_ENTER_WINDOW and
EVT_LEAVE_WINDOW are triggered at the boundary between the text field
and its scrollbar.
Are there any options to catch the mouse activity on the scrollbar of
a TextCtrl widget? (given the scrollwin events, which work fine in
Windows, aren't supported everywhere).
Ideally, I'd like to start a timer (to periodically check the scrolled
position) on entering the scrollbar area or clicking with a mouse and
destroy this timer after leaving or releasing the mouse button.
Are there any options to catch the mouse activity on the scrollbar of
a TextCtrl widget?
No, probably not. The scrollbar belongs to the text widget and it doesn't have to provide any access to it, or forward the notifications that come from it.

Thanks for the info Robin!
It's good to know in order not to vaste time with other trials;
I'll have to decide, whether its reasonable to have permanent position
checks regardless of scrolling or possibly give up this functionality
on not supporting plattforms.

Vlasta
