Gtk::Fixed an focus

[Sebastian <der-mustermann web de>]

Hi,

I derived a custom Widget from Gtk::Fixed. After construction it
receives keyboard input without any problem. After focussing an other
widget in the same window, I cannot get the focus back to my widget,
since I do not understand, how my Gtk application handles focus.

Any help much appreciated
