[SOLVED]Destruct and rePaint a widget

Vetryaspa

Hi all,

I have a problemi for "reload" a widget follow the code:

@#include "Imigliori/imigliori.h"
#include "ui_imigliori.h"
#include "CineticList/listawidget.h"
#include <QDebug>
#include <QVBoxLayout>
#include <SQLInteraction/sqlinteraction.h>

IMigliori::IMigliori(QWidget *parent) :
QWidget(parent),
ui(new Ui::IMigliori)
{
ui->setupUi(this);

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

showLista = new QLinkedList<Ristorante*>();
QString query("Select * From ristoranti where FORCHETTE = 3");
showLista = SQLInteraction::instance()->queryRequest(query);
lista = new listaWidget(showLista,this);
lista->setGeometry(0,100,360,500);

}

IMigliori::~IMigliori()
{
delete lista;
delete ui;
}

void IMigliori::paintEvent(QPaintEvent *event){
qDebug()<< "PAINT EVENT IMIGLIORI";

}

void IMigliori::gamberi(){
qDebug("Pulsante Gamberi()");
delete lista;

QString query("Select * From ristoranti where GAMBERI = 3");
showLista = SQLInteraction::instance()->queryRequest(query);
lista = new listaWidget(showLista,this);
lista->setGeometry(0,100,360,500);

// lista->update();
}
@

in the construct I create the Widget "lista" that i have declared in the .h file.

but i have to change it if i click the Button "ui->gamberi" but when i click the button the widget was deleted but was not rePaint however the construct of the widget "lista" was call.

What is my error?
