QML 属性绑定有些是不会动态变化的，给 text 一个onTextChanged 信号处理函数，然后更新文本试试看。

设计就不应该这么用

Text {
id:label_speed2;z:5;
objectName: "label_speed2";
x: 50; y:160;width: 200; height: 300;
text: "1000";
horizontalAlignment:TextInput.AlignHCenter
font.pixelSize: 160
onTextChanged :root.textChanged(label_speed_text2)
renderType: Text.NativeRendering
// font.italic: true
color: "white"
}
怎么绑定，text还是没有刷新。。
