This method is overridden from wxWindow::AcceptsFocus() and returns true only if there is no child window in the panel which can accept the focus.
Used for two-step panel construction.
Sends a wxInitDialogEvent, which in turn transfers data to the dialog via validators.
See wxWindow::SetAutoLayout(): when auto layout is on, this function gets called automatically when the window is resized.
In contrast to SetFocus() (see above) this will set the focus to the panel even if there are child windows in the panel.
