Mariusz,
I'm quite happy with navigation mouse modes provided by
OpenMap. I also created several own modes but none of them matches
your proposal.

You could use code from NavMouseMode - it displays
scaleable rectangle. You just have to calculate it's size once (when
MouseMode is selected) and then redraw according to mouse position.

PanMouseMode allows to move current map
view. You could use similar solution. Adding zooming should be easy using
AWT or Java Advanced Imaging. I assume that you want to zoom pixmap not to
redraw whole map while mouse cursor is moved.
Also take a look
at new OpenMap feature - you can use mouse roll to change scale of map.

You can just send your code to openmap-users list and Don
will add it to CVS, I think.
