fbtk_event()

bool fbtk_event	(	fbtk_widget_t *	root,
		nsfb_event_t *	event,
		int	timeout
	)

Retrive events from the framebuffer input.

Obtain events from the framebuffer input system with a timeout. Some events may be used by the toolkit instead of being returned to the caller.

Parameters

root	An fbtk widget.
event	an event structure to update.
timeout	The number of miliseconds to wait for an event. 0 means do not wait and -1 means wait foreevr.

Returns

wether event has been updated.
