The CMFCDragFrameImpl class draws the drag rectangle that appears when the user drags a pane in the standard dock mode.
class CMFCDragFrameImpl
Remarks
An object of this class is embedded in each CPane Class object. Thus, each pane that uses the CanFloat method displays a drag rectangle when the user drags it.
You can control the thickness of the drag rectangle by using AFX_GLOBAL_DATA::m_nDragFrameThicknessFloat and AFX_GLOBAL_DATA::m_nDragFrameThicknessDock.
