@defclass/title[pane% object% (area-container<%> subarea<%>)]{
|
|
|
|
A pane is a both a container and a containee area. It serves only
|
|
as a geometry management device. A @scheme[pane%]
|
|
cannot be hidden or disabled like a @scheme[panel%] object.
|
|
|
|
A @scheme[pane%] object has a degenerate placement strategy for
|
|
managing its children; it places them all in the upper left corner
|
|
and does not stretch any of them. The @scheme[horizontal-pane%] and
|
|
@scheme[vertical-pane%] classes provide useful geometry management.
|
|
|
|
See also @scheme[grow-box-spacer-pane%].
