QTextCursor position

[high_flyer]

Hi,

a bit embarrassed to ask this, but I didn't really deal with that much text and Qt4 until now.
I need to add text to a text edit, and make sure it always is added to the end of the current text.
So in case a mouse is clicked in the QTextEdit, the cursor position will not be at the end.
All though I have been reading the docs I just don't get how the position is treated.
The only clue I found was in QTextCursor documentation:

A document can be thought of as a single string of characters with the cursor's position() being between any two characters (or at the very beginning or very end of the document).

But if I check for the cursor position and when it is not atEnd() I set the position to be the length of the current text, the position doesn't change (or it does not get to be at the end)...
I know this is stupid, but I just don't get this cursor position thing.
Any pointers to the right place in the docs will be much appreciated.

Thanks.

Here is my slot to make things clear:

void MConsole::getInput()
{
    emit sig_promptText(txtInput->text().mid(m_strPrompt.size()));
    if(txtOutput->textCursor().position() != txtOutput->textCursor().atEnd())
        txtOutput->textCursor().setPosition(txtOutput->toPlainText().length());
    txtOutput->insertPlainText("\n"+txtInput->text());
    txtInput->setText(m_strPrompt);
    txtOutput->ensureCursorVisible();
}

void MConsole::getInput()
{
    emit sig_promptText(txtInput->text().mid(m_strPrompt.size()));
    if(txtOutput->textCursor().position() != txtOutput->textCursor().atEnd())
        txtOutput->textCursor().setPosition(txtOutput->toPlainText().length());
    txtOutput->insertPlainText("\n"+txtInput->text());
    txtInput->setText(m_strPrompt);
    txtOutput->ensureCursorVisible();
}

To copy to clipboard, switch view to plain text mode

hmm... ok I did some debugging, and the problem is not in the way I understood the positioning (I think) but that QTextCursor::setPosition() doen't seem to work (the way I expect it to).
Here is my debug code:

void MConsole::getInput()
{
    emit sig_promptText(txtInput->text().mid(m_strPrompt.size()));
    std::cout<<"position before:"<<txtOutput->textCursor().position()<<std::endl;
    if(txtOutput->textCursor().position() != txtOutput->textCursor().atEnd())
    {
        txtOutput->textCursor().setPosition(txtOutput->toPlainText().size());
        std::cout<<"position after:"<<txtOutput->textCursor().position()<<" size:"<<txtOutput->toPlainText().size()<<std::endl;
    }
    txtOutput->insertPlainText("\n"+txtInput->text());
    txtInput->setText(m_strPrompt);
    txtOutput->ensureCursorVisible();
}

void MConsole::getInput()
{
    emit sig_promptText(txtInput->text().mid(m_strPrompt.size()));
    std::cout<<"position before:"<<txtOutput->textCursor().position()<<std::endl;
    if(txtOutput->textCursor().position() != txtOutput->textCursor().atEnd())
    {
        txtOutput->textCursor().setPosition(txtOutput->toPlainText().size());
        std::cout<<"position after:"<<txtOutput->textCursor().position()<<" size:"<<txtOutput->toPlainText().size()<<std::endl;
    }
    txtOutput->insertPlainText("\n"+txtInput->text());
    txtInput->setText(m_strPrompt);
    txtOutput->ensureCursorVisible();
}

To copy to clipboard, switch view to plain text mode 

And here the output:

position before:10
position after:10 size:35

So it looks that although setPosition() gets 35, the position stays at 10.
Any idea what I am missing here?
If I set a position more then the strings size I get an "out of range" message in the console - the setPosition does get the right value, but why wont the cursor update to that position?

Thanks.

Notice that QTextEdit::textCursor() returns a copy. To move the cursor to the end you would do:

QTextCursor cursor = txtOutput->textCursor();
cursor.movePosition(QTextCursor::End);
txtOutput->setCursor(cursor);

QTextCursor cursor = txtOutput->textCursor();
cursor.movePosition(QTextCursor::End);
txtOutput->setCursor(cursor);

To copy to clipboard, switch view to plain text mode 

But notice that you might just do QTextEdit::append() as well.

Oh, of course!!
Ah.... I should have come to that conclusion my self
Thanks Jpn (and welcome to the team!)
