Dialog - popup dialog interactor
#include <InterViews/dialog.h>
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.
- 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.
