基于Qt5的闹钟实现代码

精品文档本程序基于QWidget实现，可以动态显示钟表，并且可以添加铃声头文件widget.h代码如下：#ifndef WIDGET_H#define WIDGET_H#include #include#include#include#include#include#include#include#include#include#include#include#include#include#include#includenamespace Ui class Widget;class Widget : public QWidget Q_OBJECTpublic: explicit Widget(QWidget *parent = 0); Widget();signals: void isCurrentTime();private: Ui:Widget *ui; void init(); void layout(); void con(); QLCDNumber *lcdNumber; QLabel *label; QTimeEdit *timeEdit; QPushButton *button; QTimer *timer; QTimer *uptimer; QTimer *dtimer; QTimer *itimer; QRect rect; int x; int y; double du; QSystemTrayIcon *trayIcon; QAction *restoreAct; QAction *quitAct; QMenu *trayIconMenu;private slots: void clockChange(); void dialogUp(); void mini(); void down(); void comToCur();protected: void closeEvent(QCloseEvent *e);#endif / WIDGET_H源文件widget.cpp代码如下：#include widget.h#include ui_widget.h#include#include#includeWidget:Widget(QWidget *parent) : QWidget(parent), ui(new Ui:Widget) ui-setupUi(this); init(); layout(); con(); void Widget:init() setWindowTitle(我的闹钟); setFixedSize(300,80); timer=new QTimer; uptimer=new QTimer; dtimer=new QTimer; itimer=new QTimer; lcdNumber=new QLCDNumber; lcdNumber-setFixedSize(150,50); lcdNumber-setDigitCount(12); lcdNumber-setSegmentStyle(QLCDNumber:Flat); lcdNumber-display(QTime:currentTime().toString(hh:mm:ss:zzz); label=new QLabel(闹钟); timeEdit=new QTimeEdit; timeEdit-setDisplayFormat(hh:mm:ss); button=new QPushButton(确定); trayIcon=new QSystemTrayIcon; trayIcon-setIcon(QIcon(:/new/prefix1/clock.ico); trayIcon-show(); setWindowIcon(QIcon(:/new/prefix1/clock.ico); restoreAct=new QAction(显示,this); quitAct=new QAction(退出,this); trayIconMenu=new QMenu; trayIconMenu-addAction(restoreAct); trayIconMenu-addAction(quitAct); trayIcon-setContextMenu(trayIconMenu); setWindowFlags(Qt:WindowStaysOnTopHint);void Widget:layout() QHBoxLayout *rightTopLay=new QHBoxLayout; rightTopLay-addWidget(label); rightTopLay-addWidget(timeEdit); QHBoxLayout *rightButtonLay=new QHBoxLayout; rightButtonLay-addStretch(); rightButtonLay-addWidget(button); QVBoxLayout *rightLay=new QVBoxLayout; rightLay-addLayout(rightTopLay); rightLay-addLayout(rightButtonLay); rightLay-addStretch(); QHBoxLayout *m=new QHBoxLayout; m-addWidget(lcdNumber); m-addLayout(rightLay); setLayout(m); QDesktopWidget *p=new QDesktopWidget; p=QApplication:desktop();/ rect=p-rect(); x=rect.right()-width()-2;/ y=rect.bottom()+30;/ setGeometry(x,y,width(),height();void Widget:con() connect(timer,SIGNAL(timeout(),this,SLOT(clockChange(); timer-start(1); connect(uptimer,SIGNAL(timeout(),this,SLOT(dialogUp(); uptimer-start(20); connect(dtimer,SIGNAL(timeout(),this,SLOT(down(); dtimer-start(20); connect(button,SIGNAL(clicked(bool),dtimer,SIGNAL(timeout(); connect(button,SIGNAL(clicked(bool),this,SLOT(mini(); connect(itimer,SIGNAL(timeout(),this,SLOT(comToCur(); itimer-start(20); connect(restoreAct,SIGNAL(triggered(bool),uptimer,SIGNAL(timeout(); connect(this,SIGNAL(isCurrentTime(),uptimer,SIGNAL(timeout(); connect(itimer,SIGNAL(timeout(),this,SLOT(comToCur(); itimer-start(20); connect(quitAct,SIGNAL(triggered(bool),this,SLOT(close();void Widget:clockChange() lcdNumber-display(QTime:currentTime().toString(hh:mm:ss:zzz);void Widget:dialogUp() show(); uptimer-start(20); if(y=rect.bottom()-height()-50) y-=2; else uptimer-stop(); setGeometry(x,y,width(),height();void Widget:down() dtimer-start(20); if(ystop(); setGeometry(x,y,width(),height();void Widget:mini() hide();void Widget:closeEvent(QCloseEvent *e) QMessageBox:information(0,退出,您确定要退出吗？);void Widget:comToCur() if(QVariant(QTime:currentTi
