 Summary: keyboard events not caught

 Initial Comment:
 Hi,

 Keyboard events are not caught on Gentoo Linux (2.6.22-gentoo-r5)
using wxWidgets GTK 2.8.7.
 This means VTK keyboard interactions won't work in a wxVTK window.

 This behaviour can be seen simply by adding a printout as the first
line in wxVTKRenderWindowInteractor::OnKeyDown() method and then
running any of the included test applications -> on any keypress the
OnKeyDown() is not invoked (no printout).

 Problem seems to be due to not passing keyboard focus to wxVTK
(wxGLCanvas) window.

 One simple fix that works for me is to add line
 SetFocus() into method wxVTKRenderWindowInteractor::OnEnter(), i.e.
when ever the VTK window is entered the keyboard focus is forced to
this window. Not sure if this works as a general fix, but I guess
similar thing should be done at least when clicking the window.

 My wxVTK versions are

  1.30 for wxVTKRenderWindowInteractor.cxx
  1.16 for wxVTKRenderWindowInteractor.h

 I've checked this also on windows, with exactly the same results.

 cheers
