[ wxwindows-Bugs-1770628 ] Modifiers with gtk 2.10 FAIL [wx-dev]

[Johannes Holzer]

Hi

Problem was: the EVT_CHAR Event did sometime not include modifiers. To
test this yourself, just start samples/keyboard and press Ctrl+1

On my SuSE 10.2 installation (gtk-2.10.6) some Key modifiers don't work
(e.g. Ctrl+1). SuSE 10.0 (gtk 2.8) did work.

Now i just tested same on Ubuntu Feisty (gtk-2.10.11), it worked fine.

It seems, my SuSE environment is evil.



  Can anybody help me in this problem?

  Hints? Advices?

  Has anyone SuSE 10.2 and does /not/ have this problem?



I need to get that working on SuSE 10.2. Can anybody see the same
Problem? Maybe this is a configuration problem (Ctrl+1 is no global hotkey).

I launched the keyboard sample on pure X11 (without even a window
manager running) on SuSE 10.2, and "Ctrl+1" shows as "1" in EVT_CHAR...
