InterViews Reference Manual -- Deck
NAME
Deck - a stack of interactors on top of each other
SYNOPSIS
#include <InterViews/deck.h>
DESCRIPTION
A deck is a scene containing interactors that are conceptually stacked on top
of each other. Only one interactor is visible at a time. A deck is useful to
implement ``paging'' through a document, or where only one of several similar
components should be visible at a time, as in applications using alternate tool
pallets or menus with alternate entries.
A deck will try to stretch or shrink the visible interactor to fill the total
space. The natural size of a deck is the maximum of its components.
A deck uses its perspective to specify which component is visible.
The components are numbered in the order in which they are inserted into the
deck, starting with one. A scroller or other interactor which operates on the
perspective can be used to allow a user to specify the component to view.
Either horizontal or vertical scrolling can be used.
PUBLIC OPERATIONS
Deck()
Construct a new deck.
void Insert(Interactor*)
Add an interactor to the deck.
void Change(Interactor*)
Notify the deck that an interactor's shape has changed. If propagation is on,
the deck recomputes its own shape and notifies its parent.
void Remove(Interactor*)
Take an interactor out of a deck.
void Flip(int count = 1)
void FlipTo(int
position)
void Top()
void
Bottom()
Perform operations on the perspective to specify the component to view. Flip
specifies the component relative to the current component. A positive value of
count specifies a component nearer to the ``bottom'' of the deck (the
components inserted last), and a negative value specifies a component nearer to
the ``top''. FlipTo specifies a component by its absolute position in the
deck. A positive value of position specifies a position from the top,
starting at 1. A negative value specifies a position from the bottom, starting
at -1. Top and Bottom are equivalent to FlipTo(1) and FlipTo(-1) respectively.
