Create Modal JDialog while things are processing

how do you create a Modal JDialog saying "loading" while a task is processing that shows after more than 3 seconds has passed?

Solution

  • If the task is to load an InputStream, see ProgressMonitorInputStream.

    E.G. (untested)

    ProgressMonitorInputStream pmis = new ProgressMonitorInputStream(
    parentComponent, message, inputStream);
ProgressMonitor pm = pmis.getProgressMonitor();
pm.setMillisToPopup(millisToPopup);

    It will be necessary to load the InputStream in a Thread in order to avoid blocking the EDT.
