下面是我的头文件:
test.h:
#ifndef __MYWIDGET__
#define __MYWIDGET__
#include
#include
#include
#include
#include
#include
#include
#include
#include
class MyWidget : public QWidget
{
Q_OBJECT
public:
MyWidget(QWidget *parent = 0);
void paintEvent(QPaintEvent *);
public slots:
void showTime();
void stopTime();
void display();
protected:
QPushButton *start;
QPushButton *pause;
QLabel *biao;
QVBoxLayout *layout;
QLineEdit *edit;
QTimer *timer;
QPainter *paint;
// void MyWidget::timerEvent(QTimerEvent *event);
int i;
int j;
};
#endif
以下是test.cpp:
#include "test.h"
MyWidget::MyWidget(QWidget *parent):QWidget(parent)
{
start = new QPushButton("start",this);
pause =new QPushButton("pause",this);
biao = new QLabel("wu",this);
edit = new QLineEdit(this);
i=0;
j=9;
connect(start, SIGNAL(clicked()), this, SLOT(showTime()));
..
