Open a JFace Dialog over another JFace Dialog [message #1113654]

Hi,

I have a custom JFace Dialog (called PropertyDialog) which extends the FormDialog. I would like to open a modal message Dialog over the PropertryDialog as soon as it opens, to display a message to the user.

How could this be accomplished? Would I have to override the open() method? Note that it is required that the PropertyDialog.open() does not return until a button is pressed on the button bar.

Thanks for your help.

Regards,
Jayant

If you want to block the dialog I would not override the open method because you would have to open your dialog before calling super.open(). By that time the FormDialog shell has not yet been created and you need to show your MessageDialog over that shell. Instead you could simply add the follwing asyncExec to your implementation of createFormContent().

getShell().getDisplay().asyncExec(new Runnable() {
   @Override
   public void run() {
      MessageDialog.openInformation(getShell(), "Some Title", "Some info to the user");
   }
});
