Re: Example on how to animate a Location object?

Hi Ed,

OpenMap does not provide built-in support for this, but that's something
you could easily do.

If you use an OMGraphic to represent your object, you will have to
regenerate() it with the current projection so it knows how to draw
itself when called. That should be done before you call repaint() on
the layer. You can add any method you need to your layer to access your
OMGraphics from another object or thread, and then take care of the
regeneration and calling repaint() for you.

The DayNightLayer is an example of how a javax.swing.Timer is used to
update an OMGraphic (that represents the dark side of the earth).

Hope this helps,

Don
