QML不使用Thin字体重量 [英] QML not using Thin font weight

问题描述

我有一个QML应用程序，使用免费的

$ b

 ＃ ## main.qml 
 FontLoader {source：qrc：/fonts/encodesans/EncodeSans-Thin.ttf} 
 FontLoader {source：qrc：/fonts/encodesans/EncodeSans-ExtraLight.ttf } 
 FontLoader {source：qrc：/fonts/encodesans/EncodeSans-Light.ttf} 
 FontLoader {id：mainFont; source：qrc：/fonts/encodesans/EncodeSans-Regular.ttf} 
 FontLoader {source：qrc：/fonts/encodesans/EncodeSans-Medium.ttf} 
 FontLoader {source：qrc ：/fonts/encodesans/EncodeSans-SemiBold.ttf} 
 FontLoader {source：qrc：/fonts/encodesans/EncodeSans-Bold.ttf} 
 FontLoader {source：qrc：/ fonts / encodesans / EncodeSans-ExtraBold.ttf} 
 FontLoader {source：qrc：/fonts/encodesans/EncodeSans-Black.ttf} 
 
列{
 TextLine {weight： Thin} 
 TextLine {weight：ExtraLight} 
 TextLine {weight：Light} 
 TextLine {weight：Normal} 
 TextLine {weight： } 
 TextLine {weight：DemiBold} 
 TextLine {weight：Bold} 
 TextLine {weight：ExtraBold} 
 TextLine {weight：Black} 
 
 $ / code> 





### TextLine.qml
导入QtQuick 2.0
文本{
属性字符串权重

text：1 2 3 4 font.weight：Font。+ weight
color：white
font {
weight：Font [weight]
family：mainFont.name
pixelSize：36

$ b $ / code $ / pre
$ b

_{在Ubuntu上使用Qt 5.6 ，如果它很重要的话。}

这是一个Qt错误： [QTBUG-53196]细字体在Qt中不起作用

您可以使用的一种解决方法是使用 styleName 属性，而是在Qt 5.6中引入的。
这种方法的缺点是，如果你的文本中有一些嵌入的粗体（使用html或者富文本），它将不起作用（如果我明白这个

你可以像这样使用它：

  ### TextLine.qml 
导入QtQuick 2.0 
文本{
属性字符串重量
 
 text：1 2 3 4 font.weight：Font。+ weight 
 color：white
 font {
 styleName：weight 
 family：mainFont.name 
 pixelSize：36 
} 
} 
  

I have a QML app using the freely-available Encode Sans font, which comes in 9 weights that match Qt 5.6's font weights.

I have added all .ttf to my project, and am using a FontLoader to load them. Everything works perfectly, except for the Thin weight of the font.

In addition to the code below I have tried providing a unique id on the FontLoader for Thin, to ensure that the family name is the same (it is). How can I debug this problem and get Thin working?

### main.qml
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-Thin.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-ExtraLight.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-Light.ttf" }
FontLoader { id:mainFont; source:"qrc:/fonts/encodesans/EncodeSans-Regular.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-Medium.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-SemiBold.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-Bold.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-ExtraBold.ttf" }
FontLoader { source:"qrc:/fonts/encodesans/EncodeSans-Black.ttf" }

Column {
  TextLine { weight:"Thin"       }
  TextLine { weight:"ExtraLight" }
  TextLine { weight:"Light"      }
  TextLine { weight:"Normal"     }
  TextLine { weight:"Medium"     }
  TextLine { weight:"DemiBold"   }
  TextLine { weight:"Bold"       }
  TextLine { weight:"ExtraBold"  }
  TextLine { weight:"Black"      }
}

### TextLine.qml
import QtQuick 2.0
Text {
  property string weight

  text: "1 2 3 4 font.weight: Font."+weight
  color:"white"
  font {
    weight: Font[weight]
    family: mainFont.name
    pixelSize: 36
  }
}

_{Using Qt 5.6 on Ubuntu, if it matters.}

解决方案

This is a Qt bug : [QTBUG-53196] Thin fonts do not work in Qt

One workaround you could use is using the styleName property instead wich was introduced in Qt 5.6 . The disadvantage of this method is that if you have some embedded bold in your text (with html or rich text), it won't work (if I understand this bug correctly).

You can use it like this :

### TextLine.qml
import QtQuick 2.0
Text {
  property string weight

  text: "1 2 3 4 font.weight: Font."+weight
  color:"white"
  font {
    styleName: weight
    family: mainFont.name
    pixelSize: 36
  }
}
