org.geomajas.puregwt.client.map.gfx.HtmlObject

Basic HTML element definition used in map rendering. Note that all HtmlObjects are actually GWT widgets.This class will create an HTML element in the constructor and set as many style info as is provided. Also all HtmlObjects will have an absolute positioning.

All getters and setters work immediately on the underlying HTML element for performance reasons. Extensions of this class can represent individual HTML tags such as images, but also groups (DIV). In this case of a group (see HtmlContainer) it is possible to attach multiple other HtmlObjects to create a tree structure.
