LVectorBase::SetLocked

#include "ltwrappr.h"

virtual L_INT LVectorBase::SetLocked(bLock)

Locks or unlocks the class object's associated vector.

This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameters

L_BOOL bLock

Flag that indicates whether to lock or unlock the class object's associated vector. Possible values are:

Value Meaning
TRUE Lock the class object's associated vector.
FALSE Unlock the class object's associated vector.

Returns

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

Comments

Locking a vector handle has precedence over locking layers within the vector handle. Therefore, if a vector handle is locked, the layers within that vector handle cannot be edited, even if the layers are not locked.

To lock a layer, set the bLocked member of a VECTORLAYERDESC structure to TRUE and update the layer information using the LVectorLayer::SetLayerDesc function.
