partners

Arguments: widget type

Returns a list of controls that are associated, in a way specified by type, with the control specified by the widget argument. Type is a symbol indicating the particular type of association. The function partner-types takes a control as its argument and returns the types of partners possible for that control. Any item in the list returned by partner-types is suitable as a value for type.

For example, the up-down-control partners of an editable-text widget can be a list of one up-down-control (if the editable-text widget has one) or nil. The tab-control partners of any control is a list of the tab-control on which this control lies, if any.
