在gtk.TextView中查找文本

Question

我有一個gtk.Textview。我想以編程方式查找並選擇TextView中的一些文本。 我有這個代碼，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) 

如果找到了文本，那麼它選擇在TextView的所有文字，但我需要它來選擇只找到的文本。

Answer 1

start_iter.forward_search返回開始的元組和終端相匹配，以便您found變量有兩個match_start和match_end在它

這應該使其工作：

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)
