Overview
A tab control can have a left margin, which is the area between the left side of the tab control and the first tab. Setting the left margin to 0 positions the first tab at the left edge of the tab control. Some tab styles have a built-in left margin, so tabs cannot start at the left edge of the control. The SftTabs/DLL Wizard can be used to determine which tab styles support tabs at the left edge of the control. If tab rows are displayed vertically, the left margin defined is used as the top margin.
See SFTTABS_CONTROL, leftMargin and rightMargin members.
