Method Detail

paint

public void paint(java.awt.Graphics g,
                  GeoTransform projection)

renders the DisplayElement to the submitted graphic context

Specified by:

paint in interface DisplayElement

Specified by:

paint in class DisplayElement_Impl

setRenderableObject

public void setRenderableObject(java.awt.Component o)

sets the object that shall be rendered

Specified by:

setRenderableObject in interface LocalizedDisplayElement

setPlacement
