Returns a pointer to the top window.
+\wxheading{Remarks}

\func{void}{SetTopWindow}{\param{wxWindow* }{window}}
-Sets the `top' window. You should normally call this from within \helpref{wxApp::OnInit}{wxapponinit} to
-let wxWindows know which is the main window.
+Sets the `top' window. You can call this from within \helpref{wxApp::OnInit}{wxapponinit} to
+let wxWindows know which is the main window. You don't have to set the top window;
+it's only a convenience so that (for example) certain dialogs without parents can use a
+specific window as the top window. If no top window is specified by the application,
+wxWindows just uses the first frame or dialog in its top-level window list, when it
+needs to use the top window.
