JavaFX program locks/freezes whilst running

Question

I'm trying to create a JavaFX program, which is working - but I am trying to get a progress bar to update whilst it is running.

However, the program just seems to freeze and locks up until it has finished processing.

Does anyone have an idea of how I can get the program not to freeze whilst running - and to get the progress bar to update whilst it processes?

Thanks

You can put the progressbar progress in a Platform.runLater(()-> progressBar.setProgress(progressValue)); so it will be executed at a later point in time.
