LVectorEllipse::UnlockObject

#include "ltwrappr.h"

virtual L_INT LVectorEllipse::UnlockObject(pEllipse)

Sets the object information of the class object.

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

Parameters

pVECTORELLIPSE pEllipse

Pointer to a VECTORELLIPSE structure that contains the vector object information to set.

Returns

Comments

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

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

Before an object has been added to the LVectorBase object, using LVectorBase::AddObject or LVectorLayer::AddObject, LVectorEllipse::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 LVectorEllipse::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 LVectorEllipse::UnlockObject ().

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

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