EnableMenuItem(signed hMenu, signed uIDEnableItem, signed
uEnable),bool,pascal,proc
DrawMenuBar(signed hWnd),bool,pascal
GetSystemMenu(signed hWnd, bool act),signed,pascal
end
code, after the window is opened where hMenu is a local long or signed

hMenu = GetSystemMenu(self.myWindow{prop:handle}, false)

the EscKey
