Hi,
I'm writing a plugin that processes a number of images after a menu item
was selected. What is the right way to do that in a way that doesn't
block the GUI with an indication of the progress? I guess I have to run
some kind of task that updates the progress after every image. Then
some GUI component displays a progress bar (with an optional cancel
button). I implemented something that is based on
javax.swing.ProgressMonitor and javax.swing.SwingWorker according to the
code sample from the Java tutorial
(https://docs.oracle.com/javase/tutorial/uiswing/examples/components/ProgressMonitorDemoProject/src/components/ProgressMonitorDemo.java),
but it's not working. The progress window opens after the 101st image
and then blocks the execution of the task.
What is the recommended JOSM way to do that? Is there a good example
where I can learn from? JOSM has a ProgressMonitor interface and some
classes that implement it, but there is no documentation and the plugins
I looked at are quite complex with an endless chain of subroutines. Any
help is appreciated.
Thanks,
Holger
