It is typically used as a model for a ListView that uses - MonthGrid as a delegate. - - \snippet qtlabscalendar-calendarmodel.qml 1 - - In addition to the \c index property, a list of model data roles - are available in the context of each delegate: - \table - \row \li \b model.month : int \li The number of the month - \row \li \b model.year : int \li The number of the year - \endtable - - The Qt Labs Calendar module uses 0-based month numbers to be consistent - with the JavaScript Date type, that is used by the QML language. This - means that \c Date::getMonth() can be passed to the methods as is. When - dealing with month numbers directly, it is highly recommended to use the - following enumeration values to avoid confusion. - - \value Calendar.January January (0) - \value Calendar.February February (1) - \value Calendar.March March (2) - \value Calendar.April April (3) - \value Calendar.May May (4) - \value Calendar.June June (5) - \value Calendar.July July (6) - \value Calendar.August August (7) - \value Calendar.September September (8) - \value Calendar.October October (9) - \value Calendar.November November (10) - \value Calendar.December December (11) - - \labs - - \sa MonthGrid, Calendar -*/ - -class QQuickCalendarModelPrivate : public QAbstractItemModelPrivate -{ - Q_DECLARE_PUBLIC(QQuickCalendarModel) - -public: - QQuickCalendarModelPrivate() : complete(false), - from(1,1,1), to(275759, 9, 25), count(0) - { - } - - static int getCount(const QDate& from, const QDate &to); - - void populate(const QDate &from, const QDate &to, bool force = false); - - bool complete; - QDate from; - QDate to; - int count; -}; - -int QQuickCalendarModelPrivate::getCount(const QDate& from, const QDate &to) -{ - if (!from.isValid() || !to.isValid()) - return 0; - - QDate f(from.year(), from.month(), 1); - QDate t(to.year(), to.month(), to.daysInMonth()); - int days = f.daysTo(t); - if (days < 0) - return 0; - - QDate r = QDate(1, 1, 1).addDays(days); - int years = r.year() - 1; - int months = r.month() - 1; - return 12 * years + months + (r.day() / t.day()); -} - -void QQuickCalendarModelPrivate::populate(const QDate &f, const QDate &t, bool force) -{ - Q_Q(QQuickCalendarModel); - if (!force && f == from && t == to) - return; - - int c = getCount(from, to); - if (c != count) { - q->beginResetModel(); - count = c; - q->endResetModel(); - emit q->countChanged(); - } else { - emit q->dataChanged(q->index(0, 0), q->index(c - 1, 0)); - } -} - -QQuickCalendarModel::QQuickCalendarModel(QObject *parent) : - QAbstractListModel(*(new QQuickCalendarModelPrivate), parent) -{ -} - -/*! - \qmlproperty date Qt.labs.calendar::CalendarModel::from - - This property holds the start date. -*/ -QDate QQuickCalendarModel::from() const -{ - Q_D(const QQuickCalendarModel); - return d->from; -} - -void QQuickCalendarModel::setFrom(const QDate &from) -{ - Q_D(QQuickCalendarModel); - if (d->from != from) { - if (d->complete) - d->populate(from, d->to); - d->from = from; - emit fromChanged(); - } -} - -/*! - \qmlproperty date Qt.labs.calendar::CalendarModel::to - - This property holds the end date. -*/ -QDate QQuickCalendarModel::to() const -{ - Q_D(const QQuickCalendarModel); - return d->to; -} - -void QQuickCalendarModel::setTo(const QDate &to) -{ - Q_D(QQuickCalendarModel); - if (d->to != to) { - if (d->complete) - d->populate(d->from, to); - d->to = to; - emit toChanged(); - } -} - -/*! - \qmlmethod int Qt.labs.calendar::CalendarModel::monthAt(int index) - - Returns the month number at the specified model \a index. -*/ -int QQuickCalendarModel::monthAt(int index) const -{ - Q_D(const QQuickCalendarModel); - return d->from.addMonths(index).month() - 1; -} - -/*! - \qmlmethod int Qt.labs.calendar::CalendarModel::yearAt(int index) - - Returns the year number at the specified model \a index. -*/ -int QQuickCalendarModel::yearAt(int index) const -{ - Q_D(const QQuickCalendarModel); - return d->from.addMonths(index).year(); -} - -/*! - \qmlmethod int Qt.labs.calendar::CalendarModel::indexOf(Date date) - - Returns the model index of the specified \a date. -*/ -int QQuickCalendarModel::indexOf(const QDate &date) const -{ - Q_D(const QQuickCalendarModel); - return d->getCount(d->from, date) - 1; -} - -/*! - \qmlmethod int Qt.labs.calendar::CalendarModel::indexOf(int year, int month) - - Returns the model index of the specified \a year and \a month. -*/ -int QQuickCalendarModel::indexOf(int year, int month) const -{ - return indexOf(QDate(year, month + 1, 1)); -} - -QVariant QQuickCalendarModel::data(const QModelIndex &index, int role) const -{ - Q_D(const QQuickCalendarModel); - if (index.isValid() && index.row() < d->count) { - switch (role) { - case MonthRole: - return monthAt(index.row()); - case YearRole: - return yearAt(index.row()); - default: - break; - } - } - return QVariant(); -} - -int QQuickCalendarModel::rowCount(const QModelIndex &parent) const -{ - Q_D(const QQuickCalendarModel); - if (!parent.isValid()) - return d->count; - return 0; -} - -QHash<int, QByteArray> QQuickCalendarModel::roleNames() const -{ - QHash<int, QByteArray> roles; - roles[MonthRole] = QByteArrayLiteral("month"); - roles[YearRole] = QByteArrayLiteral("year"); - return roles; -} - -void QQuickCalendarModel::classBegin() -{ -} - -void QQuickCalendarModel::componentComplete() -{ - Q_D(QQuickCalendarModel); - d->complete = true; - d->populate(d->from, d->to, true); -} - -QT_END_NAMESPACE |
