mainwindow.cpp

一大堆的qt程序,在qte2.3.7下全部可以很好地运行

#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent,const char *name):
            QWidget(parent,name)
{
     QFont f("Helvetica",14,QFont::Bold);
     setFont(f);
     AddButton = new QPushButton("Add",this);
     AddButton->setGeometry(50,15,90,40);
     SubButton = new QPushButton("Sub",this);
     SubButton->setGeometry(50,70,90,40);

     counter = new Counter(this);
     counter->setGeometry(50,125,90,40);
   
     QObject::connect(AddButton,SIGNAL(clicked()),
              counter,SLOT(IncCounter()));
     QObject::connect(SubButton,SIGNAL(clicked()),
              counter,SLOT(DecCounter()));
}
