【qml学习笔记】在qml中连接信号与槽

qml中的信号槽

qml中信号槽连接方式

• 通过signal.connect

signal testSig(string s,int num)
    function func(ss,ii)
    {
        console.log(ss,ii)
    }
    Component.onCompleted:
    {testSig.connect(func)}
    MouseArea
    {
        anchors.fill: parent
        onClicked: {
        testSig("test",99)
        }
    }

• 通过Connections

 signal testSig(string s,int num)
    function func(ss,ii)
    {
        console.log(ss,ii)
    }

    Connections
    {
        target: window
        onTestSig://注意大写
        {
            console.log(s,num)
        }
    }

推荐第二种

signal testSig(string s,int num)
    function func(ss,ii)
    {
        console.log(ss,ii)
    }

    Connections
    {
        target: window
        function onTestSig(s,num)
        {
            console.log(s,num);
        }
    }
