L_VecAddHyperlink

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecAddHyperlink(pVector, pObject, pTarget)

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

Parameters

pVECTORHANDLE pVector

Pointer to the vector handle.

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

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.
