Various Functions

• This property holds the format of the vertical header.

QCalendarWidget *calendar = new QCalendarWidget;
calendar->setVerticalHeaderFormat(QCalendarWidget::NoVerticalHeader);

• This property holds whether the date edit popup is enabled.When the widget is focus and then press any non-modifier key will cause a date edit to popup.

QCalendarWidget *calendar = new QCalendarWidget;
calendar->setDateEditEnabled(1);

• Property holds a value identifying the day displayed in the first column.

QCalendarWidget *calendar = new QCalendarWidget;
calendar->setFirstDayOfWeek(Qt::Wednesday);

Source File

#include <QCalendarWidget>
#include <QApplication>
#include <QPushButton>
#include <QVBoxLayout>
#include <QWidget>
#include <QWindowsStyle>
int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
	QWidget *win = new QWidget;
	QVBoxLayout *layout = new QVBoxLayout;
	QPushButton *nextyrbutton = new QPushButton("Next Year");
	QPushButton *prevyrbutton = new QPushButton("Prev Year");
	QCalendarWidget *calendar = new QCalendarWidget;
	QObject::connect(nextyrbutton,SIGNAL(clicked()),calendar,SLOT(showNextYear()));
	QObject::connect(prevyrbutton,SIGNAL(clicked()),calendar,SLOT(showPreviousYear()));
	layout->addWidget(calendar);	
	layout->addWidget(prevyrbutton);
	layout->addWidget(nextyrbutton);
	calendar->setGridVisible(true);
	win->setLayout(layout);
	win->showNormal();
 
	return app.exec();
}

• In the above example only two function for displaying next and previous year are used but there are many other function like showNextMonth,show PreviousMonth,showToday etc...
