Qt Quick 5.15.0 Connections 新语法

Connections {
    target: authManager
    onError: {
        busyContainer.visible = false
        buttonJoin.enabled = Qt.binding(function () {
            return textMeetingId.length >= 11 && textNickname.length > 0
        })
        message.error(result.msg)
    }
}

Connections {
    target: authManager
    function onError(resCode, result) {
        busyContainer.visible = false
        buttonJoin.enabled = Qt.binding(function () {
            return textMeetingId.length >= 11 && textNickname.length > 0
        })
        message.error(result.msg)
    }
}

qrc:/qml/AnonJoinPage.qml:54:5: QML Connections: Implicitly defined onFoo properties in Connections are deprecated. Use this syntax instead: function onFoo(<arguments>) { ... }
