#include "ltwrappr.h"

virtual L_INT LVectorText::UnlockObject(pObject)

Sets the object information of the class object.

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

Returns

Comments

This function is used to update the object information of the class object.

To use this method, declare a variable of type VECTORTEXT and pass the address to the LVectorText::LockObject () function. After modifying the vector object settings, call LVectorText::UnlockObject(). LVectorText::LockObject () and LVectorText::UnlockObject() should always be called in pairs.

Before an object has been added to the LVectorBase object, using LVectorBase::AddObject or LVectorLayer::AddObject, LVectorText::UnlockObject() can be used to change ALL properties of an object. However, once the object has been added to the LVectorBase object, some properties cannot be changed using LVectorText::UnlockObject(). Specifically, nPointCount, *Point, pszText, and pbyType cannot be changed. However, as long as the number of points does not change, the coordinates of the individual points can always be modified using LVectorText::UnlockObject().

To get the current object information for a class object, call LVectorText::LockObject.

LVectorText::LockObject and LVectorText::UnlockObject must be called in pairs.
