Re: JSVGCanvas in a JScrollPane again....

Thanks for your replies!

I made it work with the classes JSVGScrollCanvas and with the 
JSVGViewport done by Zachary DelProposto!! Greetings to Zach.

I am not sure what your exact problems were, but we have had 
pretty good luck with the JSVGScrollCanvas.  To zoom we simply do

AffineTransform transform = 
(AffineTransform)canvas.getRenderingTransform().clone();
double newScale = <<whatever>>
transform.scale(newScale, newScale); 		
scrollCanvas.setRenderingTransform(transform);

The JSVGScrollCanvas we used was by Jan Lolling, which can be 
found in the Batik mail archives.

Hello!

I want to put the JSVGCanvas into a JScrollPane. I'm using
       

batik-1.5b5
     

(should be a CVS Version from 2 days ago). I'm using the class
JSVGViewerFrame and modified it a little because I do not 
       

need all 
   

functions apart from zooming, panning and printing. I've 
       

done a subclass
     

extending the JSVGCanvas and implemented the Scrollable
       

Interface. All
     

works fine as long I just do nothing else than scrolling
       

with the thumbs
     

of the JScrollPane.

My problem now is to update the thumbs of the JScrollPane 
       

whenever I 
   

zoom into/out of the canvas or whenever I pan the canvas.
       

    I would guess that if you override setMySize to call
setPreferredSize(...), invalidate(), and then 
window.validate() [or perhaps pack()] would update the thumbs 
(one would hope).

    For scrolling/panning I think you need to make sure you
don't use Batik's pan (which updates the rendering transform) 
but use the JSVGScrollPane to change the canvas's location 
under the JViewport.

     

I've noticed some approachs here but I cannot get it work for my
panel.
Does anyone have a solution? Maybe a code sample?
       

   Sorry no prepped solution, or code.

     

Thanks in advance,

Michael
