I’ve got a worker thread that should wait for EDT to update the GUI before continuing execution. I’ve used the publish method to tell EDT to change something. How can i make the worker wait for that change to take place?

If it is also your same worker thread that is initiating the GUI changes, then there’s a ready-built mechanism for waiting for those changes to be made:
SwingUtilities.invokeAndWait()
should fit the bill nicely.
Another alternative would be to use SwingUtilities.invokeLater() to give the EDT some code to run which will wake your thread up once the EDT becomes idle, i.e. when it gets around to running this task. This would involve firing off
invokeLater()immediately followed by await()and hoping that the wake-up from the EDI doesn’t happen before you do thewait(). This isn’t quite foolproof with respect to timing, though.
