Dear all,
I am extending an OMGraphicsHandlerLayer to create my own layer and I come to
some problem when I want to add a JComboBox to my layer for the user to choose
something. The JComboBox do not show up on the layer as I expect. I am not
familiar to the Swing and openmap architecture and I hope to seek guideline
about where I should put the code and how to show the component up in the layer
here's my code . I just instantiate the Jcombobox in the init method and add
it to the layer there:

* should show a square that would change color when mouse is moved
* over it in 'Gesture' mode. Also clicking once brings up a message
* box and more than once brings up browser. <P>
*
* The DemoLayer has also been modified to demonstrate the first uses
* of the OMDrawingTool. The Palette has buttons that can be used to
* start the tool in several different ways.
*
* @see com.bbn.openmap.layer.DemoLayer
*
* Just added some decorated splines to test them. EL
