I'm developing a map display system. While zoomed in to a certain part of the map I would like to be able to use the mouse to "grab" the image and move it around. When the left mouse button is released the program would then fill in the newly exposed parts of the map. This is routine in proprietory systems of this type, but I don't even know what keywords to start researching in the online help. Does anyone know how to do this? An example?
With many thanks in advance
