AoiBoxDHTML

AoiBoxDHTML(widgetNode, model)

Widget to draw an Area Of Interest box of a model. The box can be drawn with the paint() method and is registered as a listener of the context AOI property. This object works entirely in pixel/line coordinate space and knows nothing about geography. This widget uses DHTML methods to draw the box. Since it does not support a targetModel property, it has to be defined as a child widget of the context of the map that the box should be drawn into. WARNING: This widget cannot be used in maps that use button controls. Button controls take care of aoi handling themselves. It is designed for use in locator map setups only. See also MAP-312

Parameters:
widgetNode - The node for this object from the Config file.
model - The model that contains this object.
