problem with replacing a background image using signal / slot

[omid]

Hi

i want to make a simple chess program. So far i've made the board using QTableWidget and loaded the piece pictures in the cells of table. Now i wnat to use signal and slot so that when user clicks a cell and then click another cell the piece picture from first cell goes to second cell, But I don't know how to do it.

Note that i don't want these "piece moves" obey the real chess rules. I only wnat to do the picture replacement between two cells . Later i will make them obey the rules.

here is the code. in this code only table's item(0,0) has a picture. can anyone say how to write a code so that when i click that item then click to item(1,1) , picture "1.bmp" goes to background of item(1,1)?

#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QHBoxLayout>
#include <QTableWidget>
#include <QHeaderView>
 
class Table : public QWidget
{
    Q_OBJECT
 
  public:
    Table(QWidget *parent = 0);
slots:
    //??????
 
};
 
 
Table::Table(QWidget *parent)
    : QWidget(parent)
{
  QHBoxLayout *hbox = new QHBoxLayout(this);
 
  QTableWidget *table = new QTableWidget(8 , 8 , this);
 
  table->setFixedSize(900,900);
  table->horizontalHeader()->setDefaultSectionSize(100);
  table->verticalHeader()->setDefaultSectionSize(100);
 
  table->horizontalHeader()->setResizeMode(QHeaderView::Fixed);
  table->verticalHeader()->setResizeMode(QHeaderView::Fixed);
 
  QString fileName = "/1.bmp";
  QPixmap pic(fileName);
 
  QBrush brush(pic);
 
  QTableWidgetItem* item = new QTableWidgetItem();
  item->setBackground(brush);
 
  table->setItem(0,0,item);
 
  hbox->addWidget(table);
  setLayout(hbox);
}
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    Table table;
 
    table.show();
 
 
    return app.exec();
}

#include <QtGui/QApplication>
#include "mainwindow.h"
#include <QHBoxLayout>
#include <QTableWidget>
#include <QHeaderView>

class Table : public QWidget
{
    Q_OBJECT

  public:
    Table(QWidget *parent = 0);
slots:
    //??????

};


Table::Table(QWidget *parent)
    : QWidget(parent)
{
  QHBoxLayout *hbox = new QHBoxLayout(this);

  QTableWidget *table = new QTableWidget(8 , 8 , this);

  table->setFixedSize(900,900);
  table->horizontalHeader()->setDefaultSectionSize(100);
  table->verticalHeader()->setDefaultSectionSize(100);

  table->horizontalHeader()->setResizeMode(QHeaderView::Fixed);
  table->verticalHeader()->setResizeMode(QHeaderView::Fixed);
  
  QString fileName = "/1.bmp";
  QPixmap pic(fileName);

  QBrush brush(pic);

  QTableWidgetItem* item = new QTableWidgetItem();
  item->setBackground(brush);

  table->setItem(0,0,item);

  hbox->addWidget(table);
  setLayout(hbox);
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    Table table;

    table.show();


    return app.exec();
}
