Hello Guy,
Apologies for the long delay in replying - I'm disorganized.
As you suggest, the best way to achieve what you want is to override
the JMapPane.paintComponent.
protected void paintComponent(Graphics g) {
// first call the map pane's method to draw the map
super.paintComponent(g);
// now draw your graphics on top of the map
....
}
Ideally the map pane would provide for one or more layers of graphics.
Someone worked on this in another unsupported module
(widgets-swing-pending) but it was never completed or documented.
If there is sufficient demand I could look at adding this to JMapPane
but that will have to wait until GeoTools 2.7.
Hope this helps. Let us know how you go.
Michael
