counter.cpp

一大堆的qt程序,在qte2.3.7下全部可以很好地运行

#include <stdio.h>
#include "counter.h"

Counter::Counter(QWidget *parent, const char *name):
         QWidget(parent,name)
{
     counter = 0;
     label = new QLabel("0",this);
     label->setAlignment(AlignVCenter | AlignHCenter);
}

void Counter::IncCounter()
{
     char str[30];
     sprintf(str,"%d",++counter);
     label->setText(str);
}

void Counter::DecCounter()
{
     char str[30];
     sprintf(str,"%d",--counter);
     label->setText(str);
}
