Qt自定义实现的日历控件

QDateTimeEdit 或 QCalendarWidget 在美化界面时都比较难实现，且很多效果都无法自定义，比如日历背景外发光的效果，于是自定义实现一个日志，所有的效果都可以自定已实现。棒棒的。

注：此博客虽为原创，但控件的自定实现为参考博主lynnhua_的一篇Qt 制作带农历的日历来实现的效果，源文地址：https://blog.csdn.net/nigoole/article/details/51320239。

先给各位看下实现后效果吧。

1. 先自定义了一个按钮，继承自QPushButton，并进行美化，让其看起来像是一个输入框。

class CalendarWidget; class DateTimeInputButton : public QPushButton { Q_OBJECT public: explicit DateTimeInputButton(QWidget *parent = 0); void setText(const QString &text); public slots: void showCalendarWidget(); QDateTime dateTime() const; QDate date() const; QTime time() const; void setDateTime(const QDateTime &dateTime); void setDate(const QDate &date); void setTime(const QTime &time); void setDateTimeRange(const QDateTime &min, const QDateTime &max); void dateTimeRange(QDateTime &min, QDateTime &max); signals: void dateTimeChanged(const QDateTime &dateTime); protected: void initStyleSheet(); void initConnect(); protected slots: void slotDayClicked(const QDateTime & dt); private: CalendarWidget* pCldrWgt; QDateTime m_dateTime; QString m_strFormat; }; DateTimeInputButton::DateTimeInputButton(QWidget *parent) : QPushButton(parent) { pCldrWgt = new CalendarWidget(this, QMenu().windowFlags() | Qt::FramelessWindowHint); initStyleSheet(); initConnect(); } void DateTimeInputButton::setText(const QString &text) { if(text.isEmpty() || QDateTime::fromString(text, m_strFormat).isNull()) return; QPushButton::setText(text); } void DateTimeInputButton::showCalendarWidget() { QPoint pt(-17, height() - 10); pt = mapToGlobal(pt); pCldrWgt->jumpToDateTime(m_dateTime); pCldrWgt->move(pt); pCldrWgt->show(); } QDateTime DateTimeInputButton::dateTime() const { return m_dateTime; } QDate DateTimeInputButton::date() const { return m_dateTime.date(); } QTime DateTimeInputButton::time() const { return m_dateTime.time(); } void DateTimeInputButton::setDateTime(const QDateTime &dateTime) { m_dateTime = dateTime; setText(m_dateTime.toString(m_strFormat)); } void DateTimeInputButton::setDate(const QDate &date) { setDateTime(QDateTime(date, m_dateTime.time())); } void DateTimeInputButton::setTime(const QTime &time) { setDateTime(QDateTime(m_dateTime.date(), time)); } void DateTimeInputButton::setDateTimeRange(const QDateTime &min, const QDateTime &max) { pCldrWgt->setDateTimeRange(min, max); } void DateTimeInputButton::dateTimeRange(QDateTime &min, QDateTime &max) { pCldrWgt->dateTimeRange(min, max); } void DateTimeInputButton::initStyleSheet() { setStyleSheet(QString( ".DateTimeInputButton" "{" "border: 1px solid #00d2ff; " "border-radius: 3px; " "background-color:#083590; " "min-height: 26px; " "padding-left: 7px; " "color:#ddf5ff; " "font-size:14px; " "border-radius: 3px; " "text-align : left; " "}" )); m_strFormat = QString("yyyy/MM/dd hh:mm"); m_dateTime = QDateTime::currentDateTime(); QString text = m_dateTime.toString(m_strFormat); QPushButton::setText(text); } void DateTimeInputButton::initConnect() { connect(this, &QAbstractButton::clicked, this, &DateTimeInputButton::showCalendarWidget); connect(pCldrWgt, &CalendarWidget::dayClicked, this, &DateTimeInputButton::slotDayClicked); } void DateTimeInputButton::slotDayClicked(const QDateTime &dt) { m_dateTime = dt; setText(dt.toString(m_strFormat)); }

2. 再实现按钮点击后，弹出的日历界面

class CalendarWidget : public QWidget { Q_OBJECT public: explicit CalendarWidget(QWidget *parent = 0, Qt::WindowFlags f = Qt::WindowFlags()); ~CalendarWidget(); int year() const; void setYear(int year); int month() const; void setMonth(int month); int day() const; void setDay(int day); int hour() const; void setHour(int h); int minute(); void setMinute(int m); void jumpToDateTime(const QDateTime& dt); void setDateTimeRange(const QDateTime &min, const QDateTime &max); void dateTimeRange(QDateTime &min, QDateTime &max); signals: void dayClicked(const QDateTime&); void selectDayChanged(const QDateTime&); private: QVBoxLayout *verLayoutCalendar; QWidget *widgetTitle; QComboBox* comboBox_Year; QComboBox* comboBox_Month; QWidget *widgetWeek; QLabel *labelWeek[Week]; QHBoxLayout *horLayoutWeek; QWidget *widgetBody; DayLabel *labelDay[42]; QGridLayout *gridLayoutBody; QWidget *widgetRight; QLabel *labelShowToday; QLabel *labelShowWeek; QLabel *labelShowDay; QLabel *labelShowNYear; QLabel *labelShowLunarDate; QLabel *labelSpacer; QLabel *labelScheduleTitle; QLabel *labelSchedule; QWidget* widget_bottom; QComboBox* comboBox_Hour; QComboBox* comboBox_min; QLabel* label_splite; QPushButton* pushBtn_Rtn; QPushButton* pushBtn_Now; QPushButton* pushBtn_Ok; QVBoxLayout *verlayoutWidgetRight; QHBoxLayout *horLayoutGlobal; private: int m_nYear; int m_nMonth; int m_nDay; int m_nHour; int m_nMin; QDateTime m_maxDt; QDateTime m_minDt; DayLabel* m_pCrtSelect; private: void initWidget(); void initDate(); void initStyleSheet(); void UpdateYear(); DayLabel* getDayLabel(int y, int m, int d); void changeCurrentSelectDay(); protected: virtual void paintEvent(QPaintEvent* e); private slots: void sltDayClicked(int type, int day); void sltShowPrevMonth(); void sltShowNextMonth(); void sltComboBoxDateChange(int); void sltComboBoxTimeChange(int); void slotPushBtnRtn(); void slotPushBtnNow(); void slotPushBtnOk(); };
