pygtk textview 字符串格式化问题

Question

我一直在尝试将 python 格式的字符串打印为 pygtk 文本视图中的表格数据，但输出出错了。但是，当将输出从 textview 控件复制到记事本或 gedit 时，它显示为格式化输出。在终端上打印也可以。

你能指导我怎么做吗？

Answer 1

正如PM 2Ring 已经在评论中怀疑的那样，您使用的是比例字体。只需导入 pango 并在您的 init 方法中添加 self.textview.modify_font(pango.FontDescription('monospace')) 即可。

但是，您应该注意，您的 textview 太小，无法很好地显示 table，对于显示这样的数据，GtkListView 与 GtkTreeStore 的组合更适合。
