Hi,
the problem is that I get occasionally a NullPointerException in the
ScrollListener of the JSVGCanvas. The variable "newview" is null in the
updateCompleted method .
Rectangle2D newview = getViewBoxRect();
So sometimes the canvas gets white and it has to be repaint. It's immediatly
repainted when I resize the frame or when I'm using the scrollbars. But I've
inserted
if (newview == null) {
canvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new Runnable() {
@Override
public void run() {
canvas.repaint();
}
});
return;
}
and this does not have any effect. Another solution maybe would be to avoid to
get the Exception. But I don't see what I'm doing wrong.

behaviour you see and what you expect? When you resize the frame the canvas is
in, does it just paint white in the areas you’d expect to see more of your SVG
document? If so, then the solution might be as simple as putting an
overflow="visible" attribute on your root <svg> element. -- Cameron
