Re: [OpenMap Users] MapMouseListner doubt?????

Hello Harpreet,

OpenMap mouse events can go to Layers and MapMouseModes.

I'd take a look at the classes in the OMGraphics package and try to do
what you want with those if you can.

If you really have to use your JPanel to build the display you want you
could always build the JPanel, then getGraphics() from it and then use
that to make an image which you can then make into an OMRaster or
OMScalingRaster. You are going to have to think about scaling the image to
fit on the map and worry about the projection scale too.

It's always possible to draw on top of the map but then you have to figure
to put where to draw your JPanel, get its graphic context anyway and then
track somehow where it went. Oh - you'll probably have to override its
paint() method too.

The OMGraphics know where they are on the map so you can go between mouse
events and latlong. They make life easier, at least for fairly simple
graphical objects.

all the best,

Adrian
