python - 在 gtk.TextView 中查找文本

Question

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。我有这段代码，但它无法正常工作。

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，但我需要它来仅选择找到的文本。

Answer 1

start_iter.forward_search 返回开始和结束匹配的元组，因此您的 found 变量同时具有 match_start 和 match_end在里面

这应该使它工作:

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)
