how can i get the QPushButton clicked on a QTable

[showben]

Hello,
I explain my problem and I hope that someone may give me the solution.

Currently I am developing a small application with graphical interfaces and that with Java and Qt

So I create a QTable (a table) and within each line there are QLabels for text and a button that emits a signal.

My table is composed of several lines and therefore more buttons, I want to know what is the button that issued the last signal or in other words which button was clicked.

I searched the web for a few hours but no way because the solution is either in C + + and I can not transcribe it in java or I have not found the solution.

thank you



public class PrecoMur {

QTableWidget table = new QTableWidget(0,7);

private QVBoxLayout glayout = new QVBoxLayout();

ArrayList data=FenetrePrincipale.mursEdit.getNomsMurs();
ArrayList data1=FenetrePrincipale.mursEdit.getEpaisseursMurs ();
ArrayList data2=FenetrePrincipale.mursEdit.getSurfacesMurs() ;
ArrayList data3=FenetrePrincipale.mursEdit.getReMurs();

ArrayList <PrecoMurB> qg=new ArrayList <PrecoMurB> ();

//constructeur
public PrecoMur()
{

ArrayList<String> labels = new ArrayList<String>();
labels.add("Nom");
labels.add("Surface");
labels.add("Epaisseur");
labels.add("Re");
labels.add("Preco");
labels.add("Modifier");
labels.add("");
table.setHorizontalHeaderLabels(labels);
table.setGridStyle(Qt.PenStyle.NoPen);
table.setAlternatingRowColors(true);
this.qg=addLigne();
glayout.addWidget(table);


for (int i=0;i<qg.size();i++)
{

qg.get(i).p.clicked.connect(this, "preconiser()");
qg.get(i).m.clicked.connect(this,"modifier()");

}




//insérer le tableau dans la groupbox infospreco
Preconisations.gb.setLayout(glayout);

}

private ArrayList addLigne() {
// TODO Auto-generated method stub
table.setRowCount(data.size());

PrecoMurB b=new PrecoMurB(fairepreco,modifierpreco,c,i);

table.setCellWidget(i, 0, new QLabel((String) data.get(i)));
table.setCellWidget(i, 2, new QLabel(data1.get(i)+" cm"));
table.setCellWidget(i, 1, new QLabel(data2.get(i)+" m²"));
table.setCellWidget(i, 3, new QLabel(data3.get(i)+" K.m²/W"));
table.setCellWidget(i, 4, b.p);
table.setCellWidget(i, 5, b.m);
table.setCellWidget(i, 6, b.c);


q.add(b);
}
table.update();
return q;
}


public void preconiser()
{
System.out.println("AAAA");
}

Have a look at QObejct::sender().
You might want to have a look at QSignalMapper.
