Hi,
set undo not working in QPlainTextEdit below

    pte1 = new QPlainTextEdit("hello\r\nDan\nhow r\nyou\nhi\nAnd\nhello\nagain \ndkd\naee\nwa\ndaf"
        "\nAnd his this is a long long long text which has to cross the widget width andersonkddkdkdk show line wrap mode function to test", this);
    pte1->setGeometry(10, 10, 400, 100);
    pte1->setBackgroundVisible(true);
    pte1->setCenterOnScroll(true);
    pte1->setCursorWidth(3);
    pte1->setDocumentTitle("Dan Document");
    pte1->setLineWrapMode(QPlainTextEdit::NoWrap);
    pte1->setMaximumBlockCount(10);
    pte1->setOverwriteMode(false);
    pte1->setPlaceholderText("Shows Status here");
    pte1->setUndoRedoEnabled(true);

Any help is very useful.

Thanks.
Dan
