QCalendarWidget使用用例总结

QT系统自带日历控件

QCalendarWidget *m_caledar = NULL; //日历控件

m_caledar = new QCalendarWidget(ui.m_widget_DOB_2);
m_caledar->setGeometry(0, 0, 303, 197);//高度一定不能小于197，否则显示不全
m_caledar->setGridVisible(false);
m_caledar->setHorizontalHeaderFormat(QCalendarWidget::ShortDayNames);
m_caledar->setVerticalHeaderFormat(QCalendarWidget::NoVerticalHeader);//不显示星期数

	/*根据当前系统设置语言种类对日历的文本进行语言种类切换*/
	SystemLanguageConfigModel* p_system_language_config = NULL;
	p_system_language_config = GetGlobalSystemLanguageConfigModel();
	QString system_language_static = p_system_language_config->GetLanguage();
	if (system_language_static == "en")
	{
		m_caledar->setLocale(QLocale::English);
	}
	else
	{
		m_caledar->setLocale(QLocale::Chinese);
	}

/样式设计/




QString strCaledarSyte = QString(“QCalendarWidget QTabWidget{alternate-background-color:#0d0d0d;background-color#141414;color:#ffffff;font:16px;}”

this->m_caledar->setStyleSheet(strCaledarSyte);

this->m_caledar->setFocusPolicy(Qt::NoFocus);//设置无焦点，点击日历时无虚线框

/设置上端左右两个箭头按钮样式/
QToolButton prevBtn = m_caledar->findChild<QToolButton>(QLatin1String(“qt_calendar_prevmonth”));
prevBtn->setIcon(QIcon("./SystemConfig/StyleUI/Pic/AddingPatientStepTwoView/left_arrow.png"));
QToolButton bextBtn = m_caledar->findChild<QToolButton>(QLatin1String(“qt_calendar_nextmonth”));
bextBtn->setIcon(QIcon("./SystemConfig/StyleUI/Pic/AddingPatientStepTwoView/right_arrow.png"));
QSpinBox spinBox = m_caledar->findChild<QSpinBox>(QLatin1String(“qt_calendar_yearedit”));

/设置年份最大值和最小值/
spinBox->setMinimum(1900);//最小年份为1900年
spinBox->setMaximum(2200);//最大年份为2200年

/点击日历选中信号槽/
connect(m_caledar, SIGNAL(clicked(const QDate &)), this, SLOT(SetEditeDataSlot(const QDate &)));

/***********************************************************************/

	Sleep(10);
	this->ui.m_widget_DOB_2->setVisible(false);
	this->SetDOBDataIsValid(false);
}

}

/***********************************************************************/

}

/日历初始化/
/***********************************************************************/
/ 点击日历设置按钮 /
/***********************************************************************/
void AddingPatientStepTwoView::ShowCalenderSlot()
{
QTextCharFormat selectday;
//刷新日历表背景颜色
QBrush brush;
QColor color("#141414");
brush.setColor(color);
selectday.setBackground(brush);
m_caledar->setDateTextFormat(m_hasseledate, selectday);

	selectday.setBackground(Qt::gray);
	m_caledar->setDateTextFormat(QDate::currentDate(), selectday);
	m_caledar->setHorizontalHeaderFormat(QCalendarWidget::ShortDayNames);
	ui.m_widget_DOB_2->setVisible(true);

}
效果如下:
