get mousecoordinates

[Erik.Leistner@xxxxxxxxxxx (Erik Leistner)]

Hi,
I have a problem with my VisADApplet. I want to set points in my display
(displayImplJ2D) with my mouse.
The first problem: When I use my mouse on the display, the display
moves. How can I disable this functionality.
Second problem: How can I get the coordinates of my mouse if mousebutton
is clicked.

Erik
