CMFCToolBarButton::m_bWrap
Specifies whether the button next to a separator will be put on the next row.
BOOL m_bWrap;
Remarks
The framework sets this data member to TRUE when the toolbar button does not fit on the current row or when you specify a layout (for example, a specific number of toolbar buttons per row).
The framework places this button on the next row if this data member is set to TRUE and the toolbar is docked horizontally or floating.
The default value of this data member is FALSE.
