解决 QT Designer 菜单无法显示中文的方法

根据 google 的结果，有说用 qtconfig 的，有说删除 /usr/lib/kde[34] 的，试过了都不行，说说我的分析和解决办法

首先，发现 qtconfig 调整字体后没有反应，怀疑配置没有正确保存，或存错了位置，于是

root@platinum ~ 

# whereis qtconfig

qtconfig: /usr/bin/qtconfig

找到 qtconfig 的位置，准备用 strace 跟踪一下

root@platinum ~ 

# strace /usr/bin/qtconfig

......

由于内容很多，省去了绝大部分，只保留了关键内容，其中红色信息很重要，找到了 qtconfig 动过的文件

经过分析，把 /root/.config/Trolltech.conf 中 fonts= 是 qtconfig 设置好的 default font

而 /root/.config/Trolltech/Designer.conf 中保存的信息就是我们关心的内容了

font="WenQuanYi Bitmap Song,10,-1,5,50,0,0,0,0,0"

useFont=true                                    

修改之后，运行 QT Designer 依然没有中文菜单，但正文部分的字体好看多了

接着修改 /root/.kde4/share/config/kdeglobals

font="WenQuanYi Bitmap Song,10,-1,5,50,0,0,0,0,0"

搞定，收工
