I don't understand the difference between:

a_widget.SetFocus();
ActiveFocus(a_widget);

Explanations...?

Thanks! Very Happy

I think that the difference is:
SetFocus will pass focus to the ctrl and take it from whatever has focus.
ActiveFocus sets the Ctrl that should have focus when the window next gets focus. There is only an immediate focus transition if the window is currently in the foreground.

I'm posting this because I've a DocEdit control on a form (which already has WantFocus() true) and I can't set the focus with docEditControl.SetFocus(), but it works with ActiveFocus(docEditControl).

You can SetFocus only to widget that is actually on the screen.

OTOH, ActiveFocus can be used always. Widget will simply get focus next time the parent gets focus.
