Indeterminate JProgressBar While Running Long Task

[Maas F. Turner]

Hi, I'm new to Java and would like to show a dummy JProgressBar in Indeterminate mode while running a long process. The long process would run in the current thread and the ProgressBar in a new thread.

Could someone please help with some sample code for how to do this?

Thanks.

Example of what I need to do:

File f = new File("...example...");
LongProcessExample z = new LongProcessExample();

//START THE PROGRESSBAR
....

//RUN THE LONG PROCESS
z.Process(f);

//CLOSE/DISPOSE THE PROGRESSBAR
...

//OUTPUT MESSAGE TO USER
z.message();

If this refers to Swing, you have that back to front. The JProgressBar needs to be addressed and queried on the EDT. A long running task needs to be launched in a background Thread, optiamlly handled by a SwingWorker.

Check out the tutorial linked from the JProgressBar API and another section of the same tutorial titled Concurrency in Swing.

And welcome to the Ranch!
