|
\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"));
|
|
\endcode
|
|
|
|
\bold {Note:} Since Qxt 0.6 QxtGlobalShortcut no more requires QxtApplication.
|
|
*/
|
|
|
|
/*!
|
|
\fn QxtGlobalShortcut::activated()
|
|
|
|
This signal is emitted when the user types the shortcut's key sequence.
|
|
|
|
\sa shortcut
