I use Red Hat 6.3 and JRE 1.7.

When opening a file chooser out of an applet it is not modal. When clicking somewhere which is not the file chooser's area it moves behind the applet and the applet is frozen until you minimize the browser to close it.

I experienced already the same problem with modal dialogs in general. But there I found a workaround: 1.

Is there a way to solve this problem under Linux or is there a Java version where this is problem does not occur?

  • Thank you for this idea. We will go in that direction. As we already have a caching mechanism implemented we will start the applet as a standalone application. – Florian Nov 15 '12 at 15:12

Convert the applet to a frame and (presuming that solves the problem) launch the frame using Java Web Start.

But just to check, do you see the same behavior in this applet? It is sand-boxed and not using the JFileChooser as such, but if you to try to open or save a file it should pop a UI in a modal dialog.

  • then result is correct JFileChooser is modal under Linux

  • Swing JComponents are lightweight then (caused) they are always behing heavyweight AWT Components

  • have to change Applet to JApplet and all Components inside to change to JComponents
