zoom area

[Renato Stancato <st...@gmail.com>]

Hi, I need to create a button to call the zoom area (ctrl+mouse left
button) and other button for pan (shift+mouse left button).
Is there an easy way to do that?
Thanks.

    I don't see how you could possibly bind these to a button
as they require an initial mouse down to 'anchor' the interaction.
If you just want a 'modal' interface to them (i.e. a zoom cursor,
or a hand cursor) where a normal click initiates the interaction,
I would just take the existing Zoom/Pan interactors batik.swing.gvt
and modify the startInteraction method to check your modal state,
rather than the modifier keys.
