I created a JFace application containing a "Close" button. In the "mouseUp" event, I placed:

Display.getCurrent().dispose();

I modified main() thusly:

if(Display.getCurrent() != null) {
Display.getCurrent().dispose();
}

Is this a reasonable way to code a JFace close application from a button? What is the preferred method of accomplishing this?

Thanx,
Bill

I would instead call the "close" function from the shell:

"* Requests that the window manager close the receiver in
* the same way it would be closed when the user clicks on
* the "close box" or performs some other platform specific
* key or mouse combination that indicates the window
* should be removed."

This seems to be the more appropriate action to me. Display.close is
more drastically and does not give corresponding promises. It should be
invoked after the disposal of the shell, though.
