Java Swing GUI hour glass
Solution 1
A JProgressBar (possibly in indetermiante mode) sounds right - put that on the tab until the data has been fetched. A well-designed UI shouldn't force the user to wait for long-running tasks to complete and instead allow them to do something else inbetween.
Solution 2
The simplest way is to just call setCursor on the appropriate component (probably the top-level window) with the appropriate Cursor.
component.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
And then set it back when you are done.
component.setCursor(Cursor.getDefaultCursor());
Solution 3
setCursor(int) is deprecated. This is probably a bit cleaner:
setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));

GATE makes user passwords much safer, it helps you to defeat peeking, keylogging, phishing and dictionary attack.

There is a
JTabbedPane
In my Swing program. When user clicks on a tab, the program takes a while to get the data and process the results, then shows the results in the selected tab.How can I display a hour glass, or something of that effect so that user knows it's processing data? Not to click on the tab again before it finishes it job.
