The Shortcut type provides a way of handling keyboard shortcuts. The shortcut can be set to one of the 标准键盘快捷键 , or it can be described with a string containing a sequence of up to four key presses that are needed to activate the shortcut.
Item { id: view property int currentIndex Shortcut { sequence: StandardKey.NextChild onActivated: view.currentIndex++ } }
It is also possible to set multiple shortcut sequences , so that the shortcut can be activated via several different sequences of key presses.
