Setting Text in QPlainTextEdit without Clearing Undo/Redo History

[Furkan]

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

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

QTextDocument *doc = plainTextEdit->document();

QTextCursor curs (doc);

curs.select (QTextCursor::Document);

curs.removeSelectedText ();

curs.insertText (newText);

To copy to clipboard, switch view to plain text mode

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

curs.removeSelectedText ();

curs.removeSelectedText ();

To copy to clipboard, switch view to plain text mode 

from my code

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

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


...too late.
