qml的TabView的title上如何显示出箭头？

[niepangu]

我根据网上的博文学习TabView,发现当Tab比较多的时候，每个Tab的title就显示不全了，
而且拥挤在一起，如何Tab多的时候能出现箭头，当单击箭头(类似Execl里的箭头，如下图2)后显示下个tab

Code:

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12
import QtQuick.Controls 1.4
import QtQuick.Controls.Styles 1.4
ApplicationWindow {
visible: true
width: 400
height: 300
maximumWidth:width
title: qsTr("Hello World")

TabView {
anchors.fill: parent
Tab {
title: "Red"
Rectangle { color: "red" }
}
Tab {
title: "Blue"
Rectangle { color: "blue" }
}
Tab {
title: "Green"
Rectangle { color: "green" }
}
Tab {
title: "Red"
Rectangle { color: "red" }
}
Tab {
title: "Blue"
Rectangle { color: "blue" }
}
Tab {
title: "Green"
Rectangle { color: "green" }
} Tab {
title: "Red"
Rectangle { color: "red" }
}
Tab {
title: "Blue"
Rectangle { color: "blue" }
}
Tab {
title: "Green"
Rectangle { color: "green" }
}
}
}
