Detailed Description

Represents a list of client-side image maps.

All image maps of a HTML page (in the future, also image maps from different HTML pages) are stored in a list, which is passed to the image, so that it is possible to deal with maps, which are defined after the image within the HTML page.

Maps are referred by instances of object::Object. These keys are typically URLs, so the type representing URLS should be derived from object::Object.

Todo:: Some methods within the key class have to be implemented, this is not clear at this time.

◆ addShapeToCurrentMap()

void dw::ImageMapsList::addShapeToCurrentMap	(	core::Shape *	shape,
		int	link
	)

Add a shape to the current map-.

"shape" is owned by the image map list, so a copy should be passed, when necessary.

◆ startNewMap()

void dw::ImageMapsList::startNewMap ( lout::object::Object * key )
