[Qt-interest] highlight multiple lines in QTextEdit

[Yifei Li]

Hi all,

I want to high light all the line in between start and end, I tried something as follows:

extras = []
        
cursor.movePosition(QTextCursor.StartOfLine)
self.setTextCursor(cursor)
highlight.cursor = self.textCursor()
extras.append(highlight)
        
start = self.start + 1
while start < self.end:
      cursor.movePosition(QTextCursor.Down)
      highlight.cursor = self.textCursor()
      extras.append(highlight)
      start = start + 1
        
self.setExtraSelections(extras)


However, only the last line is highlighted. Can someone help me fix my problem?

Thanks

Yifei
