Question

I have a swing worker which configures a serial port connection. This process takes an indeterminable time to complete, sometimes 1 minute sometimes a lot more.

My problem arises when users click a button that needs configuration data whilst the worker thread is still configuring.

I would like to know how to execute a user’s request only if the worker thread has completed. Else if worker thread in still alive, I want execution to wait until worker thread has finished.

Answer 1

• add PropertyChangeListener to SwingWorker, then you can to determine of status from SwingWorker

• have to implemented get() in the SwingWorker‘s method done(), otherwise isn’t possible to get an exeption(s) from invoked methods

• depend of code but I doubt that is possible to change setting, untill current thread ended, better could be to SwingWorker#cancel() and then to restart this instance
