一大堆的qt程序,在qte2.3.7下全部可以很好地运行

				#include 				#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);				}
