QT: Adding files to list widget

[Aashu10]

I have a tool button and a listWidget(connected by 4 tab widgets). i want some files to appear on listwidget when tool button is clicked.

connect(ui->toolButton, SIGNAL(clicked(bool)),this, SLOT() );

Not sure what the slot is going to be. below is my code for selecting files.

void MainWindow::Filemaking(int index)

    QStringList myFiles;
    QString myDir, myType;
    QListWidget *myWidget = new QListWidget;
    QString plat= ui->Platform_Combo->currentText();
    QString var= ui->Variant_Combo->currentText();

    if (index==0)
    {
        myDir.append("\\..\\1_CAN\\"+plat+"\\"+var);
        myType.append("*.can");
        myWidget = ui->listWidget_CAN;
    }
    else if (index==1)
    {
        myDir.append("\\..\\1_Triggers\\""+plat+"\\"+var);
        myType.append("*.tri");
        myWidget = ui->listWidget_TRI;
    }
    else if (index==2)
    {
        myDir.append("\\..\\3_Scripts\\""+plat+"\\"+var);
        myType.append("*.scr");
        myWidget = ui->listWidget_SCR;
    }
    else if (index==3)
    {
        myDir.append("\\..\\4_Calib\\""+plat+"\\"+var);
        myType.append("*.svl");
        myWidget = ui->listWidget_SVL;
    }
    else
    {
        myDir.append("");
        myType.append("*.*");
        myWidget->clear();
    }
    myWidget->clear();
    QString path=QDir::currentPath()+myDir+ui->Variant_Combo->currentText()+"\\";
    QDirIterator it(path, QStringList() << myType, QDir::Files);
    while (it.hasNext())
    {
        it.next();
        myFiles.append(it.fileName());
    }
    if (ui->UseCommons->isChecked())
    {
        path=QDir::currentPath()+myDir+"_common\\";
        QDirIterator it2(path, QStringList() << myType, QDir::Files, QDirIterator::Subdirectories);
        while (it2.hasNext())
        {
            it2.next();
            myFiles.append(it2.fileName());
        }
    }
    myWidget->addItems(myFiles);
}

Not sure how to assign this to tool button clicked. Not sure how to proceed ahead

This is how my tab looks: http://imgur.com/gguuWBv

@Aashu10
Check for the active tab and connect it to Filemaking .Then on a toolbutton clicked get file to display.
