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(QString),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 ...
		...
}

class MyWindow : public QMainWindow
{

	LabelWidget * m_pLabelWidget;
	Screen * m_pScreen;

	MyWindow()
	{
		connect(m_pLabelWidget,SIGNAL(buttonClicked(QString),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 ...
		...
}

To copy to clipboard, switch view to plain text mode 

Hope it helps
