class pane% : class?
superclass: object%
extends: | area-container<%>
| subarea<%>

A pane is a both a container and a containee area. It serves only as a geometry management device. A pane% cannot be hidden or disabled like a panel% object.

A pane% object has a degenerate placement strategy for managing its children: it places each child as if it was the only child of the panel. The horizontal-pane% and vertical-pane% classes provide useful geometry management for multiple children.

See also grow-box-spacer-pane%.

Changed in version 1.3 of package gui-lib: Changed the placement strategy to stretch and align children, instead of placing all children at the top-left corner.
