NAME
       Dialog - popup dialog interactor

SYNOPSIS
       #include <InterViews/dialog.h>

DESCRIPTION
       A  dialog is an interactor that handles input for a dialog box.	The dialog layout is specified by a separate interactor passed to the dia-
       log constructor.  The dialog completes when the value of an associated button state becomes non-zero.  This button state is  typically  set
       by one or more buttons in the component interactor.

PUBLIC OPERATIONS
       Dialog(ButtonState*, Interactor*, Alignment = Center)
	      Construct a new dialog with the given button state and interactor.  The alignment is used by the Popup operation.

       virtual boolean Accept()
	      Set  the	dialog button state to zero and loop reading events until the button state's value becomes non-zero.  Each event is passed
	      to is target's Handle operation.	Return true if the value is one, false otherwise.

       virtual boolean Popup(Event&, boolean placed = true)
	      Insert the dialog into the world associated with the given event.  If placed is true, align the dialog  around  the  event's  (x, y)
	      coordinate.  Otherwise, the dialog is inserted without specifying a position.  Popup then calls the Accept operation and returns its
	      value.
