Dialog(3I)                InterViews Reference Manual               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  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 interac-
              tor.  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.
