QCompleter stackoverflowタグフィールドのような複数項目をサポートする

Question

QCompleterをpysideで動作させる方法は、StackOverflowのタグエディタの動作と似ていますか？ユーザーが単語を入力できる場所にスペースがある場合、オートコンプリートに一致する単語を表示させることができますか？

それは私が何をしたいんようにこの投稿は、ようだが、それはあなたが最後の文字列を取得するロジックを実装する必要があり、これは作るために単語になりますC++に How to force QCompleter to check second word in QLineEdit

ですそれらを追加するために、私は見ていないよ

class LineEdit(QtGui.QLineEdit):

     if len(c.completionPrefix()) < 1: 
      c.popup().hide()

     c.complete() 

    def cursorWord(self, sentence): 
     p = sentence.rfind(" ") 
     if p == -1:
