How to add a a Button to a QMessageBox?

I am making a program.. And i had add an about button which shows a QMessageBox..

Code:

---

void MainWindow::on_aboutButton_clicked()
{
    QMessageBox msgBox;
        msgBox.setText("<b><big>Putsa pali! </big><b>");
        msgBox.setInformativeText("By <b>putsos</b> and <b>muni</b>. If you like it, visit our <a href=http://www.qjdfkjfbhjebfebfiofu.com>webpage</a>!");
        msgBox.setWindowTitle("Putsa pali | About");
        msgBox.setIconPixmap(QIcon(":/icons/putsa.png").pixmap(QSize(64,64)));
        msgBox.setWindowIcon(QIcon(":/icons/putsa.png"));
        msgBox.exec();
}

So how can i add a Button ( i want to add a Button "How it was Developed") left to the ok button which will close the about QMessageBox and show the How it was developed QMessageBox... ?

Maybe you should try to derive a new class from QMessageBox.

Ok and how to do that?

Maybe, you can experiment with QMessageBox::addButton(QAbstractButton*, ButtonRole), QMessageBox::addButton(const QString &, ButtonRole), QMessageBox::addButton(StandardButton), and QMessageBox::clickedButton().

I haven't actually done that,I suggest you checking the document of qt,check for the class structure of QMessageBox,and find out by which function it adds buttons,and you may overload the function.

But I recommend you to derive a class from QWidget,I think qt don't recommend using QMessageBox as a base class.

cheer up and try that;)

Never mind.. I will just create some QDialogs :)...
