How to activate frame manually in wxWidgets?

I have wxWidget application. And somewhere on my MainFrame I create new frame and call Show on it. But, if an user will do this action again, I don't want to create new frame. I want to activate previous one. I store pointer to created frame, but I don't know how to send activation coomand to him? I tried to send ActivatedEvent in createdFrame->ProcessEvents, but no sense.

Is it possible to sent activate command to a frame wxWidgets?

In fact, the wxFrame hardly ever gets the focus, because there is very little ( nothing? ) it can do with it. What usually happens is that one of the widgets contained by the frame get the focus - for example a text control so the user can start typing into it.
