Re: [OpenMap Users] Swing component on a layer

Hi Chris,

Using the MapHandler, you can easily have your layer provide Swing
widgets to the application to get picked up by other containers, and
the layer can control the visibility of the widgets so they only appear
when the layer is also visible. One easy way to do this is to have the
Layer also be a com.bbn.openmap.gui.Tool, and you return your widget
in the getFace() method. In fact, in the next release of OpenMap,
we'll be including an EditorLayer that does exactly this very thing.
You can add menus, whatever. Remember to set the
Layer.addToBeanContext() flag to true.

If you want the widget to appear over the map, that's a slightly harder
problem. Swing widgets tend to hijack all the mouse events if they are
added to any component also added to the MapBean. One way to get
around this is to use a JLayeredPane and add your MapBean to it, and
then add your swing widget to a different layer of the JLayeredPane.

Hope this helps,

Don
