Hi,
How do I terminate javascript running in an SVG document?
I have 2 SVG documents which both run infinite loop javascript programs
(timers for clocks).
I display them using JSVGCanvas and they both display and behave correctly.
However, when I switch between them, I wish to terminate the script of the
current document before loading the next document, but I get an Exception...
java.lang.IllegalStateException: Timer already cancelled.
at java.util.Timer.sched(Timer.java:312)
at java.util.Timer.schedule(Timer.java:128)
at org.apache.batik.bridge.ScriptingEnvironment$Window.setTimeout(Unknown
Source)
at
org.apache.batik.script.rhino.WindowWrapper.jsFunction_setTimeout(Unknown
Source) at inv2.invoke()
(I have listed the FULL EXCEPTION at the end)
Perhaps I am terminating the scripts incorrectly.
At present I do this......
UpdateManager updateManager = getUpdateManager();
if (updateManager != null)
{
ScriptingEnvironment se = updateManager.getScriptingEnvironment();
if (se != null)
{
se.interrupt();
}
}
How should a javascript be terminated?
thanks,
Stuart McMahon
