int CBCGPAutoHideDockBar::m_nExtraSpace
staticprotected

Defines spacing between toolbars and the left/top side of the dock bar.

When docked at the autohide dock bar, autohide toolbars shouldn't take all the dock bar's height, as it's implemented for the regular toolbars.

Use this global variable to control the spacing between autohide toolbars and the left/top bound (depends on the alignment) of the dock bars.
