Re: About drawing area's keypress event

["Norman Black" <stonybrk ix netcom com>]

I assume the drawing area is packed into a main window via some mechanism.
The drawing area must have the focus to receive key press events from the
parent. You should make sure that the drawing area widget has the CAN_FOCUS
flag, otherwise it can never receive the focus.
