      A dialog-box style window.
  
      This class is a convenient way of creating a DocumentWindow with a close button
      that can be triggered by pressing the escape key.
  
      Any of the methods available to a DocumentWindow or ResizableWindow are also
      available to this, so it can be made resizable, have a menu bar, etc.
  
      You can either override or use an instance of the DialogWindow class directly,
      or you can use a DialogWindow::LaunchOptions structure to quickly set up and
      launch a box containing a content component.
  
      If you use the class directly, you'll need to override the
      DocumentWindow::closeButtonPressed() method to handle the user clicking the close
      button - for more info, see the DocumentWindow help.
