delete-selection

Arguments: window-or-widge

Deletes the selected object (if any) in window-or-widget, if it knows how to do so for the particular window or widget. Returns true if a deletion was done, and nil otherwise.

window-or-widget should be an instance of a basic-pane subclass or a dialog-item subclass.

The default method always does nothing (and therefore returns nil). Otherwise the methods behave the same cut-selection.
