Tab Control

  • Article

A tab control defines multiple pages for the same area of a window or dialog box. Each page consists of a set of information or a group of controls that an application displays when the user selects the corresponding tab. The Windows operating system uses tab controls to display the taskbar buttons, with the exception of the Start button.

The window class name for a tab control is WC_TABCONTROL, which is defined as "SysTabControl" in Commctrl.h.
