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.
