Question

我一直在尝试在pygtk textview中将python格式的字符串作为表格数据打印，但输出错误。但是，当将textview控件的输出复制到记事本或gedit时，它会显示为格式化输出。在终端上打印也很好。

你可以指导我怎么做？

由于评论中已经怀疑 PM 2Ring ，您使用的是比例字体。只需导入pango并在init方法中添加(function(){ var imgLength = $('img').length; var current = 1; var currentImage = $('img'); $('button').on('click',function(){ if($(this).data('dir') === 'next') { current++; currentImage.animate({ 'left':'-=600px' }); if(current > imgLength) { currentImage.animate({ 'left':'0px' }); current = 1; } } if($(this).data('dir') === 'prev'){ current--; currentImage.animate({ 'left':'+=600px' }); if(current < 1) { currentImage.animate({ 'left': (600 * (1 - imgLength )) + 'px' }); current = imgLength; } } }); })();即可。

但是，你应该注意到你的textview太小了，不能很好地显示表格，而且为了显示这样的数据，GtkListView和GtkTreeStore结合起来更适合。
