QCalendarWidget tooltip

ivanicy

Hello!!

Does anyone know how to assign a tooltip to each of the cells in a qcalendarwidget?

Thank you very much!

Hi,

From the looks of it, you will have to install an event filter to catch the QEvent::ToolTip event and react on that.

@SGaist Can you help me with that? I read that I need to reimplement the QCalendarWidget class. I have this class:

#include "calendarmanager.h"

CalendarManager::CalendarManager(QWidget *parent)
    : QCalendarWidget (parent)
{
//    m_outlinePen.setColor(QColor(213,116,23));
    m_outlinePen.setColor(Qt::transparent);
    m_transparentBrush.setColor(QColor(213,116,23,50));

    getDates();
}

CalendarManager::~CalendarManager()
{

}

void CalendarManager::setColor(const QColor &color) {
    m_outlinePen.setColor(color);
}

QColor CalendarManager::getColor() const {
    return ( m_outlinePen.color() );
}

void CalendarManager::paintCell(QPainter *painter, const QRect &rect, const QDate &date) const {
    QCalendarWidget::paintCell(painter, rect, date);

    if (m_dates.contains(date)) {
        painter->setPen(m_outlinePen);
        painter->setBrush(QBrush(QColor(213,116,23,50)));
        painter->drawRect(rect.adjusted(0, 0, -1, -1));
    }
}

void CalendarManager::getDates() {
//    QFile file("C:\\Users\\Ivan\\Desktop\\prueba.txt");
//    if (!file.open(QIODevice::ReadOnly)) {
//        // Error code
//    }

//    QList<QByteArray> wordList;
//    QDate date;
//    QString name;
//    calendarEvent e;

//    while (!file.atEnd()) {
//        QByteArray line = file.readLine();
//        wordList = line.split(',');

//        date = QDate::fromString(wordList.first(), "dd/MM/yyyy");
//        name = wordList.last();

//        e.date = date;
//        e.name = name;

//        m_events.append(e);
//        m_dates.append(date);
//    }
//    file.close();
}

void CalendarManager::setDateState(QDate dtDate, bool bState) {
    /* Esta es la funcionalidad mínima necesaria para pintar un día en el calendario */
    calendarEvent e;
    e.date = dtDate;

    if (bState) {
        m_events.append(e);
        m_dates.append(dtDate);
    } else {
        for (int iDate = 0; iDate < m_events.size(); iDate++) {
            if (m_events.at(iDate).date == e.date)
                m_events.removeAt(iDate);
            if (m_dates.at(iDate) == e.date)
                m_dates.removeAt(iDate);
        }
    }
}

How I have to proceed with the event filter? I think I read that I need it inside the paintCell function but I don't know how to do it.

Thank you very much!

You have an example of event filter here.

What kind of tool tip do you want to show ?

@SGaist I only want to show a simple text associated to the selected day

SGaist

In your event filter get the Qt's event and then us a QToolTip to check the dialog you want to build.
