QtextEdit Enable Disable Auto Scroll

Hello,

I've got a debug window with a QTextEdit to display some informations, and I would like to be able to enable / disable the auto scrolling.

I tried to use QtextCursor but it doen't work.. I had a look on the documentation and I don't find how to do this.. :

here it is what I tried and doesn't work:

Code:

---

void myClass::on_pushButton_PauseTextEdit_clicked()
{
    if(ui->pushButton_PauseTextEdit->text().contains("Pause"))
    {
        //I want the QTextEdit Stop scrolling
 
        ui->pushButton_PauseTextEdit->setText("Go");
 
        cursorTextEditLog.setPosition(QTextCursor::NoMove, QTextCursor::MoveAnchor);
        ui->textEditLog->setTextCursor(cursorTextEditLog);
 
    }
    else
    {
        //I want to go down to the last information which has been append on QTextEdit and scroll
 
        ui->pushButton_PauseTextEdit->setText("Pause");
 
        cursorTextEditLog.setPosition(QTextCursor::end, QTextCursor::MoveAnchor);
        ui->textEditLog->setTextCursor(cursorTextEditLog);
    }
}

---

If someone has a clue...
Thanks.

Added after 19 minutes:

for the return to "the last information which has been append on QTextEdit and scroll" it works doing this:

Code:

---

ui->pushButton_PauseTextEdit->setText("Pause");
 
        cursorTextEditLog.movePosition(QTextCursor::end, QTextCursor::MoveAnchor,1);
        ui->textEditLog->setTextCursor(cursorTextEditLog);

Just as a suggestion: do not keep "state" in the button's text or icon.

Your check for "Pause" will break if you change the text and/or have translations.

Either have a stateful button (setCheckable(true)) or keep the state in a boolean member that is toggled by the slot.

Thank you for your advise. I did this for a quick test.

I manage to return to "the last information which has been append on QTextEdit and auto scroll. But I still don't manage to stop the scrolling when I click on pause button, but it works when I click directly in the QTextEdit.

You could try

* get the scroll bar position
* add the text
* reset the scrollbar position

Thanks, I'll try this.

Cheers.
