Thanks Don and Chris by your answers.
Don, You mentioned that it could extend from RenderPolicy, it is an interface...you mean that i have to create a class that implements that interface? (like standardRenderPolicy). I've seen at DemoLayer class the following code:
public void paint(java.awt.Graphics g) {
// Super calls the RenderPolicy that makes decisions on how to
// paint the OMGraphicList. The only reason we have this
// method overridden is to paint the legend if it exists.
super.paint(g);
if (legend != null) {
legend.paint(g);
}
}
I've seen that legend (JPanel component) is always null, if I initialize and adding a Swing component (Example, legend.add(new JButton("hello")); and execute legend.paint(g) this is not shown in the layer...
How can I paint the Swing components?. If I put layer.getGUI.paints(g) it does not appear anything about the Swing components. And there is not a setGUI...so...how can I add swing components to the layer in order to paint it after of that?
I also modified the code of paint at StandardRenderPolicy adding this: layer.getGUI().paintAll(g) but there was not success... :(
Chris, How can I put a image like a OMGraphics? I was trying with OMBitmap, but it is not refered to a window bitmap...Thanks a lot
I don't know what i'm doing wrong... I'd appreciate an example of code of this please. It's very important for me. Thank you very much
Best regards

The thing that makes this not-so-obvious is that OpenMap layers
override the paint() method so that the
com.bbn.openmap.layer.policy.RenderPolicy object handles the rendering
of the OMGraphicList, instead of using the paint(...) method hierarchy
of the Swing ancestry.
The easiest thing to do is extend a RenderPolicy class and set that on
your layer. You'll probably want the RenderPolicy object to call
paintAll(java.awt.Graphics) on the layer. In addition to painting the
OMGraphicList.
RenderPolicy object can be set in the layer's constructor, or you can
set it in the properties, too.
Hope this helps,
Don
