- \class QxtGlobalShortcut

- \brief The QxtGlobalShortcut class provides a global shortcut aka "hotkey".
-
- A global shortcut triggers even if the application is not active. This
- makes it easy to implement applications that react to certain shortcuts
- still if some other application is active or if the application is for
- example minimized to the system tray.
-
- Example usage:
- \code
- QxtGlobalShortcut* shortcut = new QxtGlobalShortcut(window);
- connect(shortcut, SIGNAL(activated()), window, SLOT(toggleVisibility()));
- shortcut->setShortcut(QKeySequence("Ctrl+Shift+F12"));
