Comments

This function will attach a vector handle to a window handle. All subsequent changes to the vector image will be reflected on the window.

Note: When you copy one vector to another using LVectorBase::Copy, and the source vector is attached to a window, the destination vector will NOT be attached to the same window automatically.

You can draw on the surface of any window using LVectorBase::Paint, but to use double buffering, you must attach the vector handle to a window.
