Hi Nikhil,

Ive managed to fix resizing on the scrollpane by setting the viewBox on
a GVTTreeRenderingCompleted event notification. But I have to do it
explicitly.

To use the JSVGScrollPane your SVG document should have a viewBox attribute on the outermost svg element. This is how it determines what the extents of the scroll bars should be. If you want you can load the SVG document yourself and add the viewBox attribute before giving the document to the canvas.

  This should be documented and there should be better checking
along with a better error message when the check fails (or it could
default to the final 'computed' bounds of the SVG - although this
can often be 'wrong'.  Contributions are always welcome.

Hi,

I was trying to use the JSVGScrollPane and it kept throwing
NullPointerExceptions. After tracing the execution I found that it seems
to check the viewBox before setting it. I hacked around this doing the
following:

public class MySVGScrollPane extends JSVGScrollPane{

public MySVGScrollPane(JSVGCanvas canvas){
    super(canvas);
    super.viewBox = new java.awt.geom.Rectangle2D.Float(0,0,10000,10000);
    super.ignoreScrollChange = false;
}
}

This keeps the scrollbars constant which is again weird it be resizing
according to changes in the document, right?


The code which uses the scroll pane is something like:

JPanel panel = new JPanel(layout...)
JSVGCanvas myCanvas = new JSVGCanvas();
myCanvas.setDocumentState(JSVGCanvas.ALWAYS_STATIC) [other options produce
the same results]

panel.add(new JVGScrollPane(myCanvas));

.....(the document is set by some user initiated action)


Am I using this the wrong way?

Thanks,
-Nikhil
