RE: [OpenMap Users] Extending CoordDialog and cretaing to CoordPa nel for AOI input

Don,

I want to figure out the new scale of the map based upon the to corner point
representing the AOI. I know I can use

newScale = com.bbn.openmap.proj.ProjMath.getScale(point1, point2,
projection);

but how to I get the projection when I am using a listener in the CoorDialog
I noticed the class CenterSupport and its setCenter method which somehow
communicates with the map to center it on the point entered. I notice that
there is a ProjectionSupport & ZoomSupport method. I was going to use
ZoomSupport to zoom my map and get the zoom factor from newScale above, if
that is the correct way. But I still need to get the projection to pass to
getScale. I though maybe there would be a some method I could call from
ProjectionSupport, but do not see one that would work. How else can I get
the map projection.

CoordInternalFrame is a CoordDialog if OpenMap is being run as an
applet.

I'd go through CoordDialog and where ever there is a call to coordPanel
and dmsPanel, incorporate your panel into that logic.

In 4.6, this whole setup completely changed, none of the panels are
hard-coded into CoordDialog, it works with the MapHandler to find the
panels and wire them together.
