Hey Marios,
Try something like this
1. assign JButton to action that sets and unsets
boolean doZoom;
2. extend class
abstract class Zoomer extends AbstractZoomInteractor(){
...
...
// end interaction defines the condition to end the zoom
public boolean endInteraction()
{
return finished;
}
// I want the zoom to end at the release of my mouse, but you
can do it anywhere else
public void mouseReleased( MouseEvent e ){
super(e);
finished = true;
}
}
3. Create instance of zoomInteractor
Interactor zoomInteractor = new Zoomer()
{
boolean finished = false;
public boolean startInteraction(InputEvent ie)
{
return doZoom;
}
};
4. Attach interactor
svgCanvas.getInteractors().add( zoomInteactor );
That's what I did and it seems to work. You can probably try something else
as well.
cheers,
-tomas

Thank you very much your advice was very helpful.But what I have not managed
to do yet is how can I ovewrite the AbstractZoomInteractor in order to add
the functionality of zoom in a particular button or menuItem(for example a
jbutton of my application). Is there any way that I can an action event
instead of an input event in the class that extends AbstractZoomInteractor?
Should I overwrite the startInteraction( InputEvent ie ) method or just
define it
Thank you in advance
Marios

Subject: JSVGCanvas ZoomIn Action problem.
Hi,
I am trying to use the zoom in capability of JSVGCanvas but I cannot access
the protected class. Furthermore I tried to override the protected class but
still I could not make it work.
Could you please tell me how can I use the zoom capabilites of JSVGCanvas?
(If it easy send me some code) How can I access the class and how can I use
it?
Thanks in advance
Marios
