#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc,argv);
    QWidget w;

    QPushButton * pb[];//QPushButton指针数组
    for(int i=;i<;i++)
    {
        pb[i] = new QPushButton("AAAAA");
    }

    QGridLayout *pg=new QGridLayout;

    pg->addWidget(pb[],,,,);  //把按钮pb添加到第0行0列，该按钮占据1行和1列单元格。
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
    pg->addWidget(pb[],,,,);
