BCGControlBar Pro for MFC
BOOL CBCGPControlBar::m_bHandleMinSize

Enables consistent handling of minimal size.

If one or more docking control bars override GetMinSize, or SetMinSize has been used in application, you may want to set this static member to TRUE in order to enable the library to handle minimal size consistently.

In this case all docking bar whose size should be reduced below their minimal size are clipped, not stretched. The library uses window regions for this purpose, therefore you must not change the window region of docking control bars.

If you encounter any side effects when this flag is being used, set it to FALSE.
