快捷键 Ctrl+Down 实战

Question

我想要一个 Action 触发快捷键 Ctrl+↓.

我能做的是 ↓:

的快捷方式

Action {
    shortcut: StandardKey.MoveToNextLine
    enabled: true
    onTriggered: console.log('Down pressed')
}

但是如何定义快捷键Ctrl+↓?

Answer 1

使用类似的东西：

Keys.onPressed: {
    if ((event.key == Qt.Key_Down) && (event.modifiers & Qt.ControlModifier))
        doSomething();
}

Answer 2

从 shortcut 的 documentation 你读到：

Shortcut bound to the action. The keysequence can be a string or a standard key.

从 QKeySequence toString() 方法 documentation 你还读到：

Return a string representation of the key sequence, based on format.

For example, the value Qt::CTRL+Qt::Key_O results in "Ctrl+O". If the key sequence has multiple key codes, each is separated by commas in the string returned, such as "Alt+X, Ctrl+Y, Z". The strings, "Ctrl", "Shift", etc. are translated using QObject::tr() in the "QShortcut" context.

因此，使用键名组合而不是像这样的 StandardKey：

import QtQuick 2.4
import QtQuick.Window 2.2
import QtQuick.Controls 1.3

ApplicationWindow {
    id: rectangle
    width: 200
    height: 200
    visible: true

    Action {
        shortcut: "Ctrl+Down"
        enabled: true
        onTriggered: console.log('Down pressed [ctrl hold]')
    }
}
