我是在VS2005下编译的,
出现这种情况,为什么啊?
#include <qapplication.h>
#include <qpushbutton.h>
#include <qfont.h>
#include <qvbox.h>
int main(int argc, char *argv[])
{
QApplication a( argc, argv );
QVBox box;
box.resize( 200, 120 );
QPushButton quit( "Quit", &box );
quit.setFont( QFont( "Times", 18, QFont::Bold ) );
QObject::connect( &quit, SIGNAL(clicked()), &a, SLOT(quit()) );
a.setMainWidget( &box );
box.show();
return a.exec();
}
