Solved Get the last two characters written in a QTextEdit

[legitnameyo]

I want to get the last two characters written in a QTextEdit. I tried the following

void MainWindow::onTextChanged() {

    QTextCursor c = textEdit->textCursor();
    c.setPosition(textEdit->cursor().pos().x());
    c.setPosition(textEdit->cursor().pos().x() - 2, QTextCursor::KeepAnchor);
    textEdit->setTextCursor(c);

    qDebug() << textEdit->textCursor().selectedText();
}

Which partially works since I get the last two characters of the text but I also highlight them and rewrite them. I want it to be impossible for the user to see or know that the last two characters were retrieved and I also want to continue to write without overwriting the last two characters in my text!

Would it alread help to remove textEdit->setTextCursor(c); and instead use qDebug() << c.selectedText(); ?

Depending on how many characters I've got in my QTextEdit I get one of these two messages

QTextCursor::setPosition: Position '458' out of range
QTextCursor::setPosition: Position '460' out of range

or if there is quite little text

""
""
""

Removing "textEdit->setTextCursor(c);" fixed the issue of the QTextEdit highlighting and removing text but makes the printing of the last two characters impossible, AKA it gives one of the two errors I mentioned above.

Edit: Wrong code, see below

QTextCursor cur = textEdit->textCursor();
newCur.movePosition(QTextCursor::PreviousCharacter,QTextCursor::KeepAnchor,2);
qDebug() << textEdit->textCursor().selectedText();
newCur.movePosition(QTextCursor::PreviousCharacter,QTextCursor::MoveAnchor,2);

@VRonin I tried

QTextCursor cur = textEdit->textCursor();
    cur.movePosition(QTextCursor::PreviousCharacter,QTextCursor::KeepAnchor,2);
    qDebug() << textEdit->textCursor().selectedText();
    cur.movePosition(QTextCursor::PreviousCharacter,QTextCursor::MoveAnchor,2);

but it gave me

""
""
""
""
""

in the console, not the last two characters... It did solve the "out of range" issue though!

sorry, sloppy coding, the correct is below:

QTextCursor cur = textEdit->textCursor();
cur.movePosition(QTextCursor::PreviousCharacter,QTextCursor::KeepAnchor,2);
qDebug() << cur.selectedText();

@VRonin it worked! thanks!

void MainWindow::onTextChanged() {
    QTextCursor cur = textEdit->textCursor();
    cur.movePosition(QTextCursor::PreviousCharacter,QTextCursor::KeepAnchor,2);
    qDebug() << cur.selectedText();
}

QString str = textEdit->toPlainText();
QString targetChars = str.mid(textEdit->textCursor().columnNumber() -2 ,2);
qDebug() <<targetChars;
