Ey Heiko! Thanks a lot for your fast answer.
Unfortunately your proposal would not work in my case because I can't
modify the task method (it's other partner code). I simply want to stop
the thread that runs that method, but I dont know how.
The situation is the following:
class RunCode implements IRunnableWithProgress{
public void run(IProgressMonitor monitor) throws
InvocationTargetException, InterruptedException {
monitor.beginTask("do something ..."
,IProgressMonitor.UNKNOWN);
other_partner_read_only_method(); //<-- problem: I can't throw
InterruptedException here
monitor.done()
}
//invoked when monitor cancel button is pressed
//HOW IMPLEMENT THIS TO STOP RUNCODE.RUN() ???
public void stopRunCode(){
}
I want to stop the Runnable from a stopRunCode() method, invoked when
the monitor is monitor.isCancelled equals true-checking that I do from a
thread that continuosly is checking for it)
