属性设置

一般情况下,使用push("qrc:///pages/xxx.qml")的方式无法对xxx.qml进行属性设置.如果需要进行属性设置则使用以下方式:(如果xxx.qml中存在abcd这个属性的话)

stackview.push({item:Qt.resolvedUrl("qrc:///pages/xxx.qml"),
    properties:{abcd:"H12345"} } );

信号连接

可以将当前的item做为参数传递给stackview push Item,然后在Item中连接信号.

Rectangle {
    id: relay

    signal messageReceived(string person, string notice)

    Component.onCompleted: {
        relay.messageReceived.connect(sendToPost)
        relay.messageReceived.connect(sendToTelegraph)
        relay.messageReceived.connect(sendToEmail)
        relay.messageReceived("Tom", "Happy Birthday")
    }

    function sendToPost(person, notice) {
        console.log("Sending to post: " + person + ", " + notice)
    }
    function sendToTelegraph(person, notice) {
        console.log("Sending to telegraph: " + person + ", " + notice)
    }
    function sendToEmail(person, notice) {
        console.log("Sending to email: " + person + ", " + notice)
    }
}
