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
