org.geomajas.puregwt.client.map.gfx.HtmlGroup

Container for {@link AbstractHtmlObject}s. This class is an extension of an {@link AbstractHtmlObject} that in turnis used to store a list of child {@link AbstractHtmlObject}s. In other words instances of this class represent the nodes in an HTML tree structure.

The main goal for this class is to provide a container for child {@link AbstractHtmlObject}s. Through it's methods these children can be managed. Note though that this class is itself also an {@link AbstractHtmlObject}, which means that this class too has a fixed size and position. Child positions are always relative to this class' position.
