removeLink

Procedure that removes a specific link between two objects.

Location: smart.p

Parameters:

INPUT phSource AS HANDLE

Source procedure handle.

INPUT pcLink AS CHARACTER

Link type name.

INPUT phTarget AS HANDLE

Link target object handle.

Notes:

This procedure both removes the handles of both Source and Target from the appropriate SmartObject properties (see addLink) and also does an UNSUBSCRIBE for each named event associated with the link.
All SmartObject links are removed when an object is destroyed. This procedure could be used in application code to remove a specific link based on application requirements.
Examples:

/* This example removed the Update link between a visual SmartObject such    as a SmartDataViewer and its associated SmartDataObject, perhaps in    response to an application event or security check which should make    the SmartDataObject non-updatable. */ hTarget = WIDGET-HANDLE(dynamic-function(‘linkHandles’, INPUT    ‘Update-Target’:U)). IF VALID-HANDLE(hTarget) THEN    RUN removeLink(THIS-PROCEDURE, ‘Update’:U, hTarget).
