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

invokeAndWait() is meant to be called from the non-GUI thread. It sends a Runnable object to the GUI thread where it will be executed.

There's no point in sending a Runnable object from the GUI-thread to itself. It has the same effect as calling run() on the Runnable object directly.
