详细描述

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.

autoRepeat : bool

This property holds whether the shortcut can auto repeat.

默认值为 true .

context : enumeration

此特性保持 shortcut context .

Supported values are:

• Qt.WindowShortcut (default) - The shortcut is active when its parent item is in an active top-level window.
• Qt.ApplicationShortcut - The shortcut is active when one of the application's windows are active.

Shortcut {
    sequence: StandardKey.Quit
    context: Qt.ApplicationShortcut
    onActivated: Qt.quit()
}
					

enabled : bool

This property holds whether the shortcut is enabled.

默认值为 true .

[since 5.6] nativeText : string

This property provides the shortcut's key sequence as a platform specific string. This means that it will be shown translated, and on macOS it will resemble a key sequence from the menu bar. It is best to display this text to the user (for example, on a tooltip).

该特性在 Qt 5.6 引入。

[since 5.6] portableText : string

This property provides the shortcut's key sequence as a string in a "portable" format, suitable for reading and writing to a file. In many cases, it will look similar to the native text on Windows and X11.

该特性在 Qt 5.6 引入。

sequence : keysequence

This property holds the shortcut's key sequence. The key sequence 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.

The default value is an empty key sequence.

Shortcut {
    sequence: "Ctrl+E,Ctrl+W"
    onActivated: edit.wrapMode = TextEdit.Wrap
}

[since 5.9] sequences : list < keysequence >

This property holds multiple key sequences for the shortcut. The key sequences can be set to one of the 标准键盘快捷键 , or they can be described with strings containing sequences of up to four key presses that are needed to activate the shortcut.

Shortcut {
    sequences: [StandardKey.Cut, "Ctrl+X", "Shift+Del"]
    onActivated: edit.cut()
}
					

该特性在 Qt 5.9 引入。

信号文档编制

activated ()

This signal is emitted when the shortcut is activated ambigously, meaning that it matches the start of more than one shortcut.

注意： 相应处理程序是 onActivatedAmbiguously .
