CAutoHideDockSite::m_nExtraSpace
The size of the space between the edges of the CAutoHideDockSite Class and the CMFCAutoHideBar Class objects.
static int m_nExtraSpace;
Remarks
When a CMFCAutoHideBar is docked at a CAutoHideDockSite, it should not occupy the whole dock site. This global variable controls the extra space between the left or top border of the CMFCAutoHideBar and the corresponding CAutoHideDockSite edge. Whether the top or left edge is used depends on the current alignment.
