Text属于用的频率比较高而且需要定义的地方又比较多的地方，看一下如下的把Text封装成Label进行使用。

使用的例子：
Label {
id: titleLabel

anchors {
left: parent.left
right: parent.right
margins: units.dp(16)
}

style: "title"
text: "Edit info"
}

封装的原始代码：

import QtQuick 2.0

Text {
id: label
property string style: "body1"

property var fontStyles: {
"display4": {
"size": 112,
"font": "light"
},

"display3": {
"size": 56,
"font": "regular"
},

"display2": {
"size": 45,
"font": "regular"
},

"display1": {
"size": 34,
"font": "regular"
},

"headline": {
"size": 24,
"font": "regular"
},

"title": {
"size": 20,
"font": "medium"
},

"dialog": {
"size": 18,
"size_desktop": 17,
"font": "regular"
},

"subheading": {
"size": 16,
"size_desktop": 15,
"font": "regular"
},

"body2": {
"size": 14,
"size_desktop": 13,
"font": "medium"
},

"body1": {
"size": 14,
"size_desktop": 13,
"font": "regular"
},

"caption": {
"size": 12,
"font": "regular"
},

"menu": {
"size": 14,
"size_desktop": 13,
"font": "medium"
},

"button": {
"size": 14,
"font": "medium"
},

"tooltip": {
"size_desktop": 10,
"size": 14,
"font": "medium"
}
}

property var fontInfo: fontStyles[style]

font.pixelSize: units.dp(!Device.isMobile && fontInfo.size_desktop
? fontInfo.size_desktop : fontInfo.size)
font.family: "Roboto"
font.weight: {
var weight = fontInfo.font

if (weight === "medium") {
return Font.DemiBold
} else if (weight === "regular") {
return Font.Normal
} else if (weight === "light") {
return Font.Light
}
}

font.capitalization: style == "button" ? Font.AllUppercase : Font.MixedCase

color: Theme.light.textColor

}
