How to open modal Swing dialog from Eclipse [message #462245]

I am developing an Eclipse plugin using some Swing classes. What is the
correct way of opening Swing dialogs from SWT? From an
org.eclipse.jface.action.Action I can open the dialog without problems
using SwingUtilities.invokeLater(...) where the dialog is opened in the
Runnable, but the resulting dialog is not modal.

I guess I haven't fully understood the event handling - are there any
online documents explaining the AWT-SWT threading issues?

Any help appreciated
Hans

Open swt dialog and put swing control in

I thought about this as well, but is this the only way? The pure Swing
dialog shows up nicely and it would be quite an overhead if I had to
reimplement control logic for close, ok etc. Furthermore I would need to
change the dialog launching code everywhere in the Swing code.

Also, assuming I do this, how can I then ensure that the Swing thread
"waits" until the SWT dialog is closed?

Thanks for any clarification
Hans

create simple swt dialog and in composite add your swing control (panel from
swing dialog)

You do have a second option which is to use the SWT_AWT.getFrame(Composite) method. This will return an instance of Frame which you can then use to parent your dialog. AFAIK, it should be modal after that.

You can wrap an SWT Shell around your existing dialog, and SWT will provide all the functionality of the Swing version. However, I do agree that it's a major overhead (not to mention maintenance problem) to do so.

This is essentially what I am doing now, but the dialog is not modal.
getFrame would just return the WEmbeddedFrame which I also get by asking
any nested Swing component for its top level ancester. Since the embedded
frame is part of the overall Eclipse Shell, the Shell is not blocked.

Unless someone else has some good ideas, I really have to wrap all Swing
dialogs with SWT Shells :( I would consider this a serious flaw in the
SWT_AWT class.

Do you try frame.setAlwaysOnTop(true) ?
