To use graphics, view, scene for repaint a text

[zabitqt]

Hi, I will develop a text editor in pyqt6 but using graphics, view and scene.
Until now I can "draw" the characters in the scene and I want to implement the following operations:

• add another text at any position of the text
  -remove some text from the text
  I mapped the characters shown in the scene into a list of list.
  I can act on this matrix for insert new characters from a position or remove characters from a position, then delete the scene and draw the text again.

This is not efficient! Is there another way?
