bool dw::core::Layout::LinkReceiver::click	(	Widget *	widget,
		int	link,
		int	img,
		int	x,
		int	y,
		EventButton *	event
	)			[virtual]

Called, when the user has clicked on a link.

For mouse interaction, this is equivalent to "press" and "release" on the same link. In this case, event contains the "release" event.

When activating links via keyboard is supported, only a "clicked" signal will be emitted, and event will be NULL.

bool dw::core::Layout::LinkReceiver::enter	(	Widget *	widget,
		int	link,
		int	img,
		int	x,
		int	y
	)			[virtual]

Called, when a link is entered, left, or the position has changed.

When a link is entered, this method is called with the respective arguments. When a link is left, this method is called with all three arguments (link, x, y) set to -1.

When coordinates are supported, a change of the coordinates also causes emitting this signal.
