Hi !
I have got some problems with the dynamic update too ...
some general points are that you have to set
svgCanvas.setDocumentState(JSVGComponent.ALWAYS_DYNAMIC);
and you have to use the updateQueue to get the dynamic updates to be performed
UpdateManager um = this.getUpdateManager();
RunnableQueue rq = um.getUpdateRunnableQueue();
rq.invokeLater( new Runnable( ){
public void run( ){
// do your DOM-changes here
}
});
My problem is that there "sometimes" is no updateManager for my JSVGCanvas allthough
the document is set) and that "sometimes" the updateRunnableQueue is not running when
I call invokeLater.
Can I perform several changes in one call of invokeLater or do I have to call it
seperately for every single attribute change (etc.) ?
Is there a good working example for using the updateRunnableQueue - I don't mean one
where the whole document changes but where only some fragments change (like the
visibility for example) ?
Greetings,
Christian.
