Your problem seems related only to GUI, where is the data ??
I am not sure of the Model View architecture... but can suggest the following pseudo code for ur problem -


class MyWindow : public QMainWindow
{

LabelWidget * m_pLabelWidget;
Screen * m_pScreen;

MyWindow()
{
connect(m_pLabelWidget,SIGNAL(buttonClicked(QStrin g),this,SLOT(handleButtonClick(QString));
}
}

void MyWindow::handleButton(QString button)
{
if(button == "1")
{
m_pScreen->changeColor(green);
// pop dialog
// other things you want to do....
}
else ...
...
}

Hope it helps :)
