We use this function in WHEN-NEW-FORM-INSTANCE trigger to maximize our forms:

PROCEDURE MAXIMIZE_WINDOWS IS
BEGIN

• Maximize MDI_WINDOW and ROOT_WINDOW set_window_property(FORMS_MDI_WINDOW,WINDOW_STATE,MAXIMIZE); set_window_property('ROOT_WINDOW',WINDOW_STATE,MAXIMIZE); END;

The ROOT_WINDOW is the main window in the each our form.

I hope this will help you.
