Displaying a checker board with each square as an object - C++ QT

I'm new to Qt but not too C++. I'm trying to create a checker/chess board where each square is an object. What I'm trying to figure out is how to have each square object be a part of the board object I'm declaring and display that on the screen. I can display a widget on the screen by using MyWidget.show() in the main class. But I want to do something like Board.show() and have all of the square objects that are members of that class(that have a height, width, and color) show up. With the code I tried nothing showed up, although I was able to get a square to show up that was NOT in the board class.

main.cpp

#include <qtgui>
#include "square.h"
#include "board.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    //Square square;
    //square.show();
    Board board;
    board.show();
    return app.exec();
}

board.h and board.cpp

#ifndef BOARD_H
#define BOARD_H

#include <QWidget>

class Board : public QWidget
{
public:
    Board();
};

#endif // BOARD_H

#include "board.h"
#include "square.h"

Board::Board()
{
    Square square;
    //square.show();
}

square.h and square.cpp

#ifndef SQUARE_H
#define SQUARE_H

#include <QWidget>

class Square : public QWidget
{
public:
    开发者_StackOverflow中文版Square();

protected:
    void paintEvent(QPaintEvent *);
};

#endif // SQUARE_H

#include "square.h"
#include <QtGui>

Square::Square()
{
    QPalette palette(Square::palette());
    palette.setColor(backgroundRole(), Qt::white);
    setPalette(palette);
}

void Square::paintEvent(QPaintEvent *)
{
    QPainter painter(this);
    painter.setRenderHint(QPainter::Antialiasing);
    painter.setBrush(QBrush("#c56c00"));
    painter.drawRect(10, 15, 90, 60);
}

Again, I'm a noob with Qt, so most of what my code was guess work and what I could find on google.

A few things going wrong in the code:

1. You are creating the Square object on the stack. in the Board::Board() constructor. The square is created and deleted right away when it gets out of the constructor. So create it on the heap.
2. The Square needs a parent so when you create a square do
   square = new Square(this);
3. Your board is basically a collection of squares so create a variable QVector<Square*> squaresVec in the private members of Board class. Now in the Board() constructor create as many squares as required and insert them into a QGridLayout (at the same time save the pointers in the squaresVec variable for future purposes). Then use this->setLayout(gridLayout);
4. Also, your square widget doesn't have a size so set a size (simply use resize())

1. use QGridLayout for Board
2. set fixed size for each square (and may be size policy).
3. set board as parent of each square (Square square(this);).
