I installed Qt4 realized the differences early on.. will work with 4.x
only & will buy the book!.

i was just playing with this

        QTextEdit *text = new QTextEdit(vbox);
        QPushButton *greet = new QPushButton("Greet", vbox);
        QTextEdit *text2 = new QTextEdit(vbox);
        QPushButton *quita = new QPushButton("Quit", vbox);

        text->setText("");
        text2->setText("");

        QObject::connect(greet, SIGNAL(clicked()),
                        text2, SLOT(setText(QString)));
        QObject::connect(text, SIGNAL(valueChanged()),
                        text2, SLOT(setText(QString)));

on clicking greet, display the entered text of "text" in  "text2",
whats the correct way?
i guess may figure that out few lessons down, but nyways asking :)
