main.cpp

一大堆的qt程序,在qte2.3.7下全部可以很好地运行

#include <qlabel.h>
#include <qapplication.h>
#include <qfont.h>
#include <qpushbutton.h>

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

       QLabel *label = new QLabel("",0);
       char str[30]="asdfasdf";
       label->setGeometry(20,20,150,240);
       label->setText(str);
       label->setFont(QFont("couries",24));
       label->setAlignment(Qt::AlignHCenter |Qt:: AlignVCenter);
       label->show();
       app.setMainWidget(label);    
       QPushButton *button = new QPushButton("ok",label);
       button->setGeometry(45,200,60,40);
       button->setFont(QFont("times",16));
       button->show();   

       return app.exec();
}
