Description

The function pane-restore-display restores the disabled display of the pane pane if possible.

If the display of pane is disabled and can be restored, the function pane-restore-display restores it and returns t. Otherwise it returns nil.

The display of a pane may be disabled to a "restorable" state by some feature, typically a restart around the display callback. For example, if there is an error inside the display-callback of an output-pane, a restart is added that removes the display callback. If this restart is used, the output-pane is not displayed (its display-callback is not called) until it is restored (or the display-callback gets set explicitly).

Examples

The Window Browser tool in the LispWorks IDE uses pane-restore-display in the Enable Display item in its menu.
