L_VecAddHyperlink

Summary

Adds a new item to the target list for the specified hyperlinked vector object.

Syntax

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecAddHyperlink(pVector, pObject, pTarget)

Parameters

pVECTOROBJECT pObject

Pointer to a VECTOROBJECT structure that references a vector object. The target list of this hyperlinked vector object will be updated with the new target.

pVECTORLINKDESC pTarget

Pointer to a VECTORLINKDESC structure that determines how the toolkit will handle the hyperlink.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Hyperlinked vector objects cause some action to take place when the end-user clicks on them. Each of these objects maintains a list of targets. That is, clicking on a hyperlinked vector object may cause several different things to occur. Depending on the target(s) and how the user specifies handling the target(s), the vector toolkit will act in response to the end-user's actions on that target.

A hyperlink must be added to a vector object using this function before it can be changed using the L_VecSetHyperlink function.
