LVectorText::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 LVectorText::UnlockObject(pText)

Parameters

pVECTORTEXT pText

Pointer to a VECTORTEXT 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 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.
