Setting Text in QPlainTextEdit without Clearing Undo/Redo History

Hello.
How can I set text in QPlainTextEdit without clearing the undo/redo history?

You can try

1. access to the document
2. create a text cursor
3. select all text in the document
4. delete selected text
5. insert new text

Code:

---

QTextDocument *doc = plainTextEdit->document();
 
QTextCursor curs (doc);
 
curs.select (QTextCursor::Document);
 
curs.removeSelectedText ();
 
curs.insertText (newText);

---

I haven't tried it, but maybe using QCursor directly wont clear the history.


...too late.

Thank you so much. It works. But it also takes the empty document (When you remove selected text) into the undo/redo history.

delete the line

Code:

---

curs.removeSelectedText ();

---

from my code

How could I not think about that!?
Thank you so much. It works perfect now!
