main.cpp

一大堆的qt程序,在qte2.3.7下全部可以很好地运行

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


int main( int argc, char **argv )

{

    QApplication a( argc, argv );


    QPushButton quit( "Quit", 0 );

    quit.resize( 75, 30 );


    QObject::connect( &quit, SIGNAL(clicked()), qApp, SLOT(quit()) );
    a.setMainWidget( &quit );
    quit.show();
    return a.exec();
}
