calling invokeAndWait from the EDT

Question

I have a problem following from my previous problem. I also have the code SwingUtillities.invokeAndWait somewhere else in the code base, but when I remove this

Answer 1

You can check before if your current calling thread is already the event dispatcher:

private void syncExec(final Runnable r) {
    try {
        if (EventQueue.isDispatchThread()) r.run();
        else EventQueue.invokeAndWait(r);
    } catch (final Exception e) {
        Throws.throwRuntime(e);
    }
}

Note that SwingUtilities.invokeAndWait(Runnable) simply delegates to the EventQueue.
