QML 多页面切换

利用 Loader 实现不同页面的动态切换，效果如下：

---

---

 1，加载默认页面  Component.onCompleted: showMainPage()

 2，定义  加载页面函数

    function showGeneralSettingsPage()//常规设置
    {
        panelLoader.setSource("qrc:/qml/GeneralSettings.qml")
    }

    function showLinkPage()//连接设置
    {
         panelLoader.setSource("qrc:/qml/LinkSettings.qml")
    }

 

  3，不同 按钮按下后，调用 不同函数

 onClicked: {
        showLinkPage()
}
