Hi !

I really need for today an answer to a problem which seems to be simple :
how to open a modal dialog from an applet ?

Before java 1.5, i did it by creating a JDialog with the frame owner :
(Frame)myApplet.getParent(), but this doesn't work anymore ! The cast is now
false (in Internet Explorer 6).

If anybody has an idea, it would be great !!

Thank you all

Best regards

what returns myApplet.getParent().getClass().getName() ?

Thank you Andrey, here is the information :

myApplet.getParent().getClass().getName() is sun.applet.AppletViewerPanel
and its superclass is sun.applet.AppletPanel.

Use new JFrame, as shown here :

Thank you Paul but the dialog on the example is not modal in my Intenet
Explorer.

That's a hack and modal dialog boxes are evil.

However, I believe applet.getParent().getParent() will give you the Frame.

Thank you all. I had a solution for both the AppletViewer and Internet
Explorer. I'm not sure it's ok for firefox.
The solution is to fin the
(Frame)SwingUtilities.getAncestorOfClass(Frame.class, myApplet) and use it
as owner for the dialog.
