11 *
12 *  This file is an extract of \c %shobjidl.h from <b>Microsoft Windows SDK v7.0A</b>.
13 *  It is needed to support <b>Windows 7 Taskbar Extensions</b> (namely, <em>Progress Bars</em>)
14 *  and contains minimal required definition of \c ITaskbarList3 interface.
15 *
16 *  Tested with \b MSVC and \b mingw32. Doesn't need <b>Windows 7 SDK</b> itself.
17 *
18 * \note Don't forget to link to \b ole32 library when using this file (usually \c -lole32 linker flag is enough).

This functionality includes thumbnail representations and switch targets based on individual tabs in a tabbed application, thumbnail toolbars, notification and status overlays, and progress indicators.
