隐藏 Qt 虚拟键盘中的键

Question

有没有办法在不使用自定义布局的情况下从虚拟键盘隐藏语言选择键？

Answer 1

我能够通过解决方法隐藏语言密钥：

    property var keyboardLayout: inputPanel.keyboard.layout


    function findChildByProperty(parent, propertyName, propertyValue, compareCb) {
        var obj = null
        if (parent === null)
            return null
        var children = parent.children
        for (var i = 0; i < children.length; i++) {
            obj = children[i]
            if (obj.hasOwnProperty(propertyName)) {
                if (compareCb !== null) {
                    if (compareCb(obj[propertyName], propertyValue))
                        break
                } else if (obj[propertyName] === propertyValue) {
                    break
                }
            }
            obj = findChildByProperty(obj, propertyName, propertyValue, compareCb)
            if (obj)
                break
        }
        return obj
    }



    onKeyboardLayoutChanged: {
        if(keyboardLayout!=""){
            var ChangeLanguageKey= findChildByProperty(inputPanel.keyboard, "objectName", "changeLanguageKey", null)
            if(ChangeLanguageKey){
                ChangeLanguageKey.visible=false
            }
        }
    }


    InputPanel {
        id: inputPanel
        z: 99
        y: parent.height
        anchors.left: parent.left
        anchors.right: parent.right




        states: State {
            name: "visible"

            when: inputPanel.active
            PropertyChanges {
                target: inputPanel
                y: parent.height - inputPanel.height
            }
        }
        transitions: Transition {
            from: ""
            to: "visible"
            reversible: true
            ParallelAnimation {
                NumberAnimation {
                    properties: "y"
                    duration: 400
                    easing.type: Easing.InOutBack
                }
            }
        }





        CustomComponents.AutoScroller {

            id:autoscroller

            panelY: inputPanel.y
        }


    }

这仅适用于版本 5.9，其中 objectname 属性使用“changeLanguageKey”定义，对于以前的版本，请在源代码中设置该属性并重新编译。
