Hello Thomas,
thanks for your response.
My class extends JSVGCanvas.
I add this to an scrollpane and implements scrollable.
If I resize my window bigger than the svg document-size than you can see as a white
rectangle the svg document, surrounded with th grey background from the viewport.
here a methode from scrollable interface:
/**
* @see javax.swing.Scrollable#getPreferredScrollableViewportSize()
*/
public Dimension getPreferredScrollableViewportSize() {
return getPreferredSize();
}
This all works god. If I load an larger image then canvas size than scrollbars appears.
Now I will change the size from my svg-document (e.g. makes it larger) and hope the
canvas will get notice from it - but unfortunatly he did not show any reaction.
A workaround can be to save the modified document (in DOM my changes takes effect !)
and reload it. But this method seemes to be overkill and is not very performant.
Jan

As you might imagine the outermost SVG element is a bit of a
special case. Also I might point out that there are several possible
implementations for responding to this change (like resizing the
window, or just updating the clip - if overflow is hidden). What are
you 'expecting' to happen?
