Imo not possible with QPlainTextEdit - you have to use QTextEdit

Why do you say this? You know better than I, but from https://doc.qt.io/qt-5/qplaintextedit.html#using-qplaintextedit-as-an-editor

Selection of text is handled by the QTextCursor class, which provides functionality for creating selections, retrieving the text contents or deleting selections. You can retrieve the object that corresponds with the user-visible cursor using the textCursor() method.

Isn't that what @ELEMENTICY needs?

@JonB You're right - I was under the impression that QPlainTextEdit killed this in favor of speed. But it's not the case.

Hi
I think you can just do
ui->plainTextEdit->insertPlainText ("\t\t\t\tTEXT");
