Dialog(3I)

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
   dialog  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.
