QT5在arm板上的汉字显示

1、准备好字库 xx.ttf文件

2、将xx.ttf放到 /usr/share/fonts/ 和 /usr/lib/fonts/ 下   （我自己这块板子需要两个地方都放，可以尝试只放在/usr/share/fonts/下）

3、执行fc-cache -fv 更新缓存

4、执行 fc-list可以参看arm已经支持的字体

root@am57xx-evm:/usr/bin# fc-list

/usr/share/fonts/ttf/LiberationSans-Italic.ttf: Liberation Sans:style=Italic

/usr/share/fonts/ttf/LiberationMono-Regular.ttf: Liberation Mono:style=Regular

/usr/share/fonts/ttf/LiberationSans-Bold.ttf: Liberation Sans:style=Bold

/usr/share/fonts/ttf/LiberationMono-BoldItalic.ttf: Liberation Mono:style=Bold Italic

/usr/share/fonts/ttf/LiberationSans-Regular.ttf: Liberation Sans:style=Regular

/usr/share/fonts/ttf/LiberationSerif-Bold.ttf: Liberation Serif:style=Bold

/usr/share/fonts/ttf/LiberationMono-Italic.ttf: Liberation Mono:style=Italic

/usr/share/fonts/ttf/LiberationSerif-Italic.ttf: Liberation Serif:style=Italic

/usr/share/fonts/ttf/LiberationSerif-Regular.ttf: Liberation Serif:style=Regular

/usr/share/fonts/ttf/LiberationMono-Bold.ttf: Liberation Mono:style=Bold

root@am57xx-evm:/usr/bin# 

5、在QT5应用中添加 以微软雅黑为例

   QFont font("Microsoft YaHei");

   a.setFont(font);

   

6、重启即可
