    Default cursor.atEnd returns true, cursor is at start?

    I am clearly doing something stupid that a newbie does, but I can't solve this. Here is my test code:
    Qt Code:
    1. ui->TextEdit->setPlainText("testing\n");
    2. QTextCursor cursor( ui->TextEdit->textCursor() );
    3. cursor.movePosition (QTextCursor::End, QTextCursor::MoveAnchor);
    4. if(cursor.atEnd())
    5. {
    6. ui->TextEdit->insertPlainText("true\n");
    7. };
    To copy to clipboard, switch view to plain text mode 
    This prints:

    true
    testing

    I would expect the lines in different order. What am I missing?

    The Qt doc clearly states.

    QTextCursor QTextEdit::textCursor () const

    Returns a copy of the QTextCursor that represents the currently visible cursor. Note that changes on the returned cursor do not affect QTextEdit's cursor; use setTextCursor() to update the visible cursor.

    just use the moveCursor method form QTextEdit

    I did read the documentation, but clearly from a wrong place. Besides, you can't always rely on snippets from the Internet, as demonstrated. Thanks for pointers!
