analogclock1.cpp

一个用QT3写的模拟时钟的源码包,用于时间的显示。为那些初次用QT编程的爱好者一个很好的实例。

#include <qapplication.h>
#include "AnalogClock1.h"
#include <qtimer.h>
#include <qpainter.h>

AnalogClock::AnalogClock(QWidget *parent,const char *name):QWidget(parent,name)
{
	QTimer timer = new QTimer;
	QTime time = QTime::currentTime();
	connect(timer,SIGNAL(timeout()),time,SLOT(update()));
	timer.start(1000);
}

void AnalogClock::paintEvent(QPaintEvent *)
{
	QPainter painter(this);
	painter.save();
}
int main(int argc, char *argv[])
{
	QApplication app(argc,argv);
	AnalogClock clock = new AnalogClock;
	clock.resize(100,100);
	clock.setCaption("AnalogClock");
	clock.show();
	return app.exec();
