The simplest way to do this is to wait for the IDCMP message ACTIVEWINDOW
for activating the window. So your code goes (Note this is psuedo code
I don't have the manuals in front of me, check calling arguments against
the Rom Kernel Manual) ...

	ModifyIDCMP(MyWindow,ACTIVEWINDOW);
	WindowToFront(MyWindow);
	WaitPort(MyWindow->UserPort);
	msg = (struct IntuiMessage *)GetMsg(MyWindow->UserPort);
	/* Should be an ACTIVEWINDOW message */
	--- Check for it here ---
	ReplyMsg(msg); /* Reply to it! */
	ModifyIDCMP(MyWindow,NOACTIVEWINDOW);

I don't know if there are IDCMP messages for your window coming to the front
but I thing there are.

These views are my own and no one elses. They could be yours too, just
call MrgCop() and then ReThinkDisplay()!
