How can I do something when the user clicks on a specific part of the text in a QTextEdit? I can't figure it out..

I've tried:

def addmsg(textedit, nick, message):
   textedit.cursor.insertText("<")
   nickframe = textedit.cursor.insertFrame(QTextFrameFormat())
   nickframe.nick = nick
   framecursor = nickframe.firstCursorPosition()
   framecursor.insertText(nick)
   textedit.cursor.insertText("> ")
   colorify(textedit, message)
   textedit.cursor.insertHtml("<br>")

and then, in the QTextEdit subclass..

def mousePressEvent(self, e):
    print(f"{getattr(self.cursorForPosition(e.pos()).currentFrame(), 'nick', None)=}")
    print(f"{self.cursorForPosition(e.pos()).position()=}")
    print(f"{self.cursorForPosition(e.pos()).currentFrame()=}")
    print(f"{self.cursorForPosition(e.pos()).currentFrame().document().toPlainText()=}")
    print(f"{getattr(self.cursor.currentFrame(), 'nick', None)=}")
    print(f"{self.cursor.position()=}")

but there's two problems with this. one, self.cursorForPosition(e.pos()).currentFrame().document().toPlainText() always returns the whole document text, not the specific frame i'm trying to click on, and, of course, {getattr(self.cursor.currentFrame(), 'nick', None) is always None, and two, where I insert the frame it creates a newline, which I need it not to do.

I also tried:

class TextFragment(QTextDocumentFragment):
  def __init__(self, textdocument):
    QTextFragment.__init__(self, textdocument)
  def event(self, e):
    print(f"{e.type=}")
    
def addmsg(textedit, nick, message):
  if config.show_timestamp:
    obj_now = datetime.now()
    textedit.insertPlainText(f"[{obj_now.hour: >2}:{obj_now.minute: >2}] ")
  textedit.cursor.insertText("<")
  nickdoc = TextFragment(QTextDocument(nick, textedit))
  nickdoc.nick = nick
  textedit.cursor.insertFragment(nickdoc)
  textedit.cursor.insertText("> ")
  colorify(textedit, message)
  textedit.cursor.insertHtml("<br>")

but, as i expected, the event function apparently isn't triggered when I click on the text fragment.

I don't know what else to try.. Thanks.
