QML 實作導航欄 類似于TabBar

利用QML實作導航欄的功能。可以自己修改相關的樣式，實作完全的自定制。

代碼如下

BaseButton.qml

import QtQuick 
import QtQuick.Controls 
import QtQuick.Controls.Styles 
import QtGraphicalEffects 

Rectangle{
    id : navigrect;
    property string mtextstr: "text"
    function noclicked()
    {
        p1text.color = "#00CCFF";
        p1text.font.bold = false;
        navigrect.color = "#00498C";
        //navigrect.color
    }
    function onSelected()
    {
        p1text.color = "white";
        p1text.font.bold = true;
        navigrect.color = "#1B96D1";

    }

    x:;
    anchors.verticalCenter : parent.verticalCenter
    width: parent.pbwidth;height: parent.pbheight
    radius: 
    color: "#00498C"
    border.color: "#06E4F3"
    Text {
        id : p1text
        anchors.centerIn : parent
        color: "#00CCFF"
        text: mtextstr

    }
    Behavior on color{
            PropertyAnimation{duration: }
        }

    // color:curindex==?GColor.淺綠色["500"]:GColor.淺藍色["500"]
}
