Overview

Proxy for org.eclipse.swt.widgets.Dialog superclass of dialogs like FileDialog, DirectoryDialog, ColorDialog, and FontDialog

(if you’re seeking the ‘dialog` keyword, that’s just a ‘shell` variation under ShellProxy instead.

Automatically uses the current shell if one is open. Otherwise, it instantiates a new shell parent

Optionally takes a shell as an argument

Follows the Proxy Design Pattern
