#include<QtGui> 
int main(int argc,char **argv)

    QApplication app(argc,argv); 
    QDialog *dialog=new QDialog;//创建一个对话框 
    QHBoxLayout *topLeftLayout=new QHBoxLayout;//创建水平布局器

    QPushButton *pushButton1=new QPushButton("Find");//创建按钮 
    QPushButton *pushButton2=new QPushButton("Close"); 
    rightLayout->addWidget(pushButton1);
