Focus on an non focusable window

Hi Guys,

I'm writing some kind of property sheet and I noticed that
tabbing
from a wx.TextCtrl to another wx.TextCtrl (which are the
only two
focusable elements on my wx.Frame) leaves a gap in the
focusing.

This is what happens;

Focus on wx.TextCtrl  -> TAB
Focus on something invisible -> TAB
Focus on wx.TextCtrl
Focus on something invisible -> TAB
etc.

This is consistent on wxGTK and wxMSW, I did derive a
wx.Panel to get
a custom text and better click abilities, but AFAIK a
wx.Panel should
not steal the focus.

I read something about a derived method AcceptsFocus and
AcceptsFocusFromKeyboard where you can return False to avoid
focussing
but this does not seem to help.

Are there any other elements in wxWidgets that can have
focus but have
no input? So far I used only wx.Panel, and a spacer in my
sizer, but
nothing else actually.

Regards,
- Jorgen

You need to derive from wx.PyPanel for these C++ virtual
method calls to 
be reflected to the Python method, but as you guessed the
default 
behavior for a panel is to not take the focus if it has a
child it can 
pass it on to instead.

Try making a timer whose handler prints the value of 
wx.Window.FindFocus() and see what it prints when your focus
is not 
where you expect it to be.

Hi Robin,

It seems the wx.Panel does get the focus because I added a
EVT_GET_FOCUS and colored the background red, and the panel
responsible got red. The panel had no other controls, only a
custom
evt_paint.

Thanks for the tip about using wx.PyPanel I will see if that
prevents
the panel from stealing the focus..
