LVectorRectangle::UnlockObject

Summary

Sets the object information of the class object.

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

Syntax

virtual L_INT LVectorRectangle::UnlockObject(pRectangle)

Parameters

pVECTORRECTANGLE pRectangle

Pointer to a VECTORRECTANGLE 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 VECTORRECTANGLE and pass the address to the LVectorRectangle::LockObject () function. After modifying the vector object settings, call LVectorRectangle::UnlockObject(). LVectorRectangle::LockObject () and LVectorRectangle::UnlockObject() should always be called in pairs.

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

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

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