wxFrame key events

[Matthias Buelow]

Hi folks,

I'm trying to catch EVT_KEY_DOWN and EVT_KEY_UP in an application's
wxFrame; on wxGTK, I only see EVT_KEY_UP. On Windows, I only see
EVT_KEY_DOWN, but depending on where in the frame I click (apparently,
some kind of invisible keyboard focus is transferred to children.) Have
others encountered these problems and solved them in a satisfying way? I
simply want to catch a couple key events unconditionally, no matter
where in the application the keyboard focus is.
I'm using wxWidgets 2.8.7.

Thanks.
