invokeAndWaitUninterruptibly

public static void invokeAndWaitUninterruptibly(Runnable task)
                                         throws InvocationTargetException

Throws:

InvocationTargetException

invokeAndWaitUninterruptibly

public static void invokeAndWaitUninterruptibly(Runnable task,
                                                long startTimeout)
                                         throws EventDispatchTimeoutException,
                                                InvocationTargetException

Invokes the given task on the AWT Event Dispatching Thread (EDT) and waits until it's finished. If this method is called on the EDT itself, it will just invoke the given task.

If the current thread gets interrupted while waiting for the EDT to finish the task, then waiting is continued normally, but the current thread's interrupt status is set upon return.

Parameters:

task - The Runnable whose run method should be executed synchronously in the EDT.

startTimeout - If positive, then this parameter specifies the maximum time to wait before the EDT starts to process task in milliseconds.

Throws:

IllegalArgumentException - If startTimeout is negative.

EventDispatchTimeoutException - If startTimeout is positive and waiting for the EDT to start processing the task timed out. The task has been cancelled, i.e. it will not be executed.

InvocationTargetException - If an exception is thrown when running task. getCause() yields the cause of this exception, which must be a RuntimeException or an Error.
