I give another example in the hope of making my problem clear. :-)
This is the naive solution:
if (this.svgCanvas.getSVGDocument() != null){
//do something with the SVGDocument
}else{
this.svgCanvas.addSVGLoadEventDispatcherListener(new
SVGLoadEventDispatcherAdapter() {
@Override
public void
svgLoadEventDispatchStarted(SVGLoadEventDispatcherEvent e) {
//do something with the SVGDocument
}
});
}
I checks whether the SVGDocument can be retrieved (that means: loading has
finished) and modifies it directly. Otherwise it sets up the
LoadEventDispatcherListener to get triggered when loading has finished and
then does the modifications.
The problem is: It is possible that the SVGDocument is null, but directly
after calling getSVGDocument() the loading finishes. Therefore the
svgLoadEventDispatcherEvent gets triggered _before_ I am able to set it
up.
And that is what I am trying to avoid. I need a way to _reliably_ get a
reference to the SVGDocument
