Re: focus behavior

[Lorenzo Gil Sanchez <lgs sicem biz>]

I've found the answer to my question so I'll share it with the list just
in case someone ever run into the same problem.

I had a bug in my size_allocate method. I did something like:

  if (GTK_WIDGET_REALIZED (widget))
    {
      widget->allocation = *allocation;
      gdk_window_move_resize (widget->window,
                              allocation->x, allocation->y,
                              allocation->width, allocation->height);
   }

while I should be doing this:

  widget->allocation = *allocation;
  if (GTK_WIDGET_REALIZED (widget))
    {
      gdk_window_move_resize (widget->window,
                              allocation->x, allocation->y,
                              allocation->width, allocation->height);
   }

Don't ask me why but this fixed the focus problem. Without this fix if I
put my widget in a window with several other widgets my widget gets the
focus as soon as the window is displayed.
