Can't read text in a readonly TextEditor

Oh I just found this thread: TextEditor text colour not updated after lookAndFeelChanged()/parent change - #2 by jules

Meaning that thats for the default text but still I don’t understand why if I:

  1. set a lookAndFeel
  2. setText in my TextEditor
    It doesn’t apply the default colour from lookAndFeel.

If I TYPE something new then it’s black as I selected. But the text setted with setText is still white.
