Hello,
You must use the Updatemanager, otherwise you will get problems of
synchronisation !
Eg...
if (ag.getUpdateManager() != null) {
ag.getUpdateManager().getUpdateRunnableQueue().invokeLater(
new Runnable() {
public void run() {
layerManager.setOverlayVisibility(overlayNames, visibility);
}
});
} else {
// Without UpdateManager --> set layer visibility directly
layerManager.setOverlayVisibility(overlayNames, visibility);
}
In this case the SVGDocument is searched for elements that should be displayed
or not.. Depending on the layernames and the visibility flag...
Changing something in the svgdocument should only be made within the
updatemanager... ! I had a lot of problems with that because i always get a
ConcurrentModification Exception and after that you can't load new documents !!
Mit freundlichen Grüßen Michael Kerschbaum
