CAnimationRect::m_bFixedSize
Specifies whether the rectangle has fixed size.
BOOL m_bFixedSize;
Remarks
If this member is true, then the size of rectangle is fixed and right and bottom values are recalculated each time the top-left corner is moved according to the fixed size. Set this value to TRUE to easily move the rectangle around the screen. In this case transitions applied to right and bottom coordinates are ignored. The size is stored internally when you construct the object and/or call SetDefaultValue. By default this member is set to FALSE.
