toolbutton action is not happening.

Yes, read the docs to QObject::sender()

Better would be using a QSignalMapper, but if you want use the sender() see what is the output of

void MainWindow::openClassInClientArea()
{
    qWarning() << QObject::sender();
}

void MainWindow::openClassInClientArea()
{
    qWarning() << QObject::sender();
}

To copy to clipboard, switch view to plain text mode 

when you click the different buttons.

Hi
m_classroomActionList->sender()->objectName(); is giving error.
error: `QObject* QObject::sender() const' is protected.
