Python 在gtk.TextView中查找文本

我有一个

gtk.Textview

。我想以编程方式查找并选择此

TextView

中的一些文本。 我有这个代码，但它不能正常工作

search_str =  self.text_to_find.get_text()
start_iter =  textbuffer.get_start_iter() 
match_start = textbuffer.get_start_iter() 
match_end =   textbuffer.get_end_iter() 
found =       start_iter.forward_search(search_str,0, None) 
if found: 
   textbuffer.select_range(match_start,match_end)

---

如果找到文本，则它会选择

TextView

中的所有文本，但我需要它只选择找到的文本。

start\u iter.forward\u search

返回开始和结束匹配的元组，以便

found

变量中既有

match\u start

又有

match\u end

这将使它发挥作用：

search_str =  self.text_to_find.get_text()
start_iter =  textbuffer.get_start_iter()
# don't need these lines anymore
#match_start = textbuffer.get_start_iter() 
#match_end =   textbuffer.get_end_iter() 
found =       start_iter.forward_search(search_str,0, None) 
if found:
   match_start,match_end = found #add this line to get match_start and match_end
   textbuffer.select_range(match_start,match_end)

谢谢你的回复，你真的帮助了我！
