I study qt at the initial stage.
There is a code (slightly modified from Max Schlee's book):

#include <QtWidgets>

// ----------------------------------------------------------------------
int main(int argc, char** argv)
{
    QApplication app(argc, argv);
    QTextEdit* txt = new QTextEdit;
    QTextEdit* txttwo = new QTextEdit;
    QWidget    wgt;
    QLabel* lbl = new QLabel;
   QString stri = "123";
    txt->setHtml("<HTML>"
                "<BODY BGCOLOR=MAGENTA>"
                "<H2><CENTER>Gnome Poem 3: Magic Magic</CENTER></H2>"

                "<FONT COLOR=BLUE>"
                "<P ALIGN=\"center\">"
                    "<I>"
                    "Magic! Magic!<BR>"
                    "Are you here?<BR>"
                    "Abra-ca-dabra!<BR>"
                    "We appear.<BR><BR>"
                    "Magic! Magic!<BR>"
                    "Gnomes are we.<BR>"
                    "Magic gnomes<BR>"
                    "Of mystery.<BR>"
                    "..."
                    "</I>"
                "</P>"
                "</FONT>"
                "</BODY>"
                "</HTML>"
               );
    txttwo->setText(txt->toHtml());
    //QObject::connect(txttwo,SIGNAL(textChanged()), txt,SLOT(clear()));
    QObject::connect(txttwo,SIGNAL(textChanged()), txt,SLOT(setHtml(stri)));
    QHBoxLayout* pvv = new QHBoxLayout;
    pvv->addWidget(txttwo);
    pvv->addWidget(txt);
    pvv->addWidget(lbl);
    wgt.setLayout(pvv);
    wgt.show();
    return app.exec();
}

I want to write the line "123" to txt when editing txttwo
qt gives out:

QObject::connect: No such slot QTextEdit::setHtml("123") in ..\TextEdit\main.cpp:55

Some other slots work. Such as clear() for example. But the setHtml and setPlainText slots don't work. Why is that? Tell me the correct option, without writing an additional slot?
Thanks in advance.

Please close the question. I found a very stupid mistake, I should have read the description of connect normally
