一.效果
基于网络代码修改，支持时、分、秒；支持滑动、翻页和旋转。
二.实现
#include <QtCore>#include <QPainter>#include <QAction>#include <QWidget>#include <QMainWindow>#include <QTimer>#include <QKeyEvent>#include <QResizeEvent>#include <QApplication>// 绘制数字钟白色背景和数字.class Digits: public QWidget{ Q_OBJECTpublic: // 数字动效：滑动、翻页和旋转. enum { Slide, Flip, Rotate }; Digits(QWidget *parent) : QWidget(parent) , m_number(0) , m_transition(Slide) { setAttribute(Qt::WA_OpaquePaintEvent, true); setAttribute(Qt::WA_NoSystemBackground, true); // 定时刷新. connect(&m_animator, SIGNAL(frameChanged(int)), SLOT(update())); m_animator.setFrameRange(0, 100);
