Class

Summary

A subclass of simple-layout that displays only one of its children at a time, and provides functionality for switching the displayed child to one of the other children.

Superclasses

simple-layout

Slots

visible-child

The currently visible child from the children.

Accessors

switchable-layout-visible-child

Description

The switchable-layout is passed a list of children to be its initial list of children, and also the initially visible child (which defaults to the first of the children). It inherits all of its layout behavior from simple-layout as it only ever lays out one child at a time.

Example

(setq children (list

                (make-instance 'capi:push-button

                               :text "Press Me")

                (make-instance 'capi:list-panel

                               :items '(1 2 3 4 5))))

(setq layout (capi:contain

              (make-instance

               'capi:switchable-layout

               :description children)

              :process nil))

(setf (capi:switchable-layout-visible-child layout)

      (second children))

(setf (capi:switchable-layout-visible-child layout)

      (first children))
