SwingWorker is used for the following purposes:
- For running long-running tasks in a different thread so as to prevent the GUI from being unresponsive
- For updating GUI with the results produced by the long-running task at the end of the task through
done()method. - For updating GUI from time to time with the intermediate results produced and published by the task with the help of
publish()andprocess()methods.
SwingUtilities.invokeLater() can perform the above tasks as follows:
- Instead of executing
SwingWorker.execute()method from the EDT, we can executeExecutorService.submit(new MyRunnable())as it will also create another thread which can execute long-running task. - For updating GUI at the end of the task, we can put code (written in
done()method of case1)SwingUtilites.invokeLater(new RunnableToExecuteDoneMethodCode())at the end of the task. - For updating GUI in the middle of the task, we can put code (written in
process()method of case1)SwingUtilites.invokeLater(new RunnableToExecuteProcessMethodCode())at the place where we calledpublish()method in case1.
I am asking this question because the problem specified in question http://stackoverflow.com/questions/2797483/java-swingworker-can-we-call-one-swingworker-from-other-swingworker-instead-o/2824306#2824306 can be solved by SwingUtilities.invokeLater() but can't be solved with SwingWorker
