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
}
