void QextMdiChildView::activate (  ) 

This method does the same as focusInEvent(). That's why it is a replacement for the setFocus() call. It makes sense if you for instance want to focus (I mean raise and activate) this view although the real focus is in another toplevel widget. focusInEvent() will never get called in that case and your setFocus() call for this widget would fail without any effect. Use this method with caution, it always raises the view and pushes the taskbar button. Also when the focus is still on another MDI view in the same toplevel window where this is located!
