如何使用Qpainter在Qt中绘制棋盘

Question

i have been able to draw only one rectangle but i need to draw 64 rectangles using a painter. so please can anyone help me..? i need 64 rectangles with different co_ordinates so plz help me how to change the coordinates. should i hardcode the x and y co-ordinates.

the code is as follows:

#include <QPaintEvent>
#include <QMainWindow>
void paintEvent(QPaintEvent *event)
{
  QRect rectangle(0,0,100,100);
  QPainter painter;
  painter.setBrush(Qt::black);
  painter.drawRext(rectangle);
}

Answer 1

void paintEvent()
{
int x=0,y=0;
int temp=0;
QPainter painter;
for(int i=0;i<8;i++)
{
for(int j=0;j<8;j++)
{
   if(temp==0)
{
painter.setBrush(Qt::black);
temp++;
}
else
{
painter.setBrush(Qt::white);
temp--;
}
   QRect r(x,y,100,100);
   painter.drawRect(r);
   x+=100;
}
x=0;
y+=100;
if(temp==0)
temp=1;
else
 temp=0;
}
}
