That means it has to be installed as event filter for its children, if it has children, and it has to pass mouse events from the children to itself. See eventFilter(). Some comments on the movement of multi-day items: Basically, the agenda items are arranged in two implicit double-linked lists. The mMultiItemInfo works like before to describe the currently viewed multi-item. When moving, new events might need to be added to the beginning or the end of the multi-item sequence, or events might need to be hidden. I cannot just delete this items, since I have to restore/show them if the move is reset (i.e. if a drag started). So internally, I keep another doubly-linked list which is longer than the one defined by mMultiItemInfo, but includes the multi-item sequence, too. The mStartMoveInfo stores the first and last item of the multi-item sequence when the move started. The prev and next members of mStartMoveInfo are used for that longer sequence including all (shown and hidden) items. */ class EVENTVIEWS_EXPORT AgendaItem : public QWidget, public CalendarSupport::CellItem { Q_OBJECT public: typedef QPointer QPtr; typedef QList List; AgendaItem( EventView *eventView, const Akonadi::ETMCalendar::Ptr &calendar, const Akonadi::Item &incidence, int itemPos, int itemCount, const KDateTime &qd, bool isSelected, QWidget *parent ); ~AgendaItem(); int cellXLeft() const { return mCellXLeft; } int cellXRight() const { return mCellXRight; } int cellYTop() const { return mCellYTop; } int cellYBottom() const { return mCellYBottom; } int cellHeight() const; int cellWidth() const; int itemPos() const { return mItemPos; } int itemCount() const { return mItemCount; } void setCellXY( int X, int YTop, int YBottom ); void setCellY( int YTop, int YBottom ); void setCellX( int XLeft, int XRight ); void setCellXRight( int XRight ); /** Start movement */ void startMove(); /** Reset to original values */ void resetMove(); /** End the movement (i.e. clean up) */ void endMove(); void moveRelative( int dx, int dy ); /** * Expands the item's top. * * @param dy delta y, number of units to be added to mCellYTop * @param allowOverLimit If false, the new mCellYTop can't be bigger than * mCellYBottom, instead, it gets mCellYBottom's value. * If true, @p dy is always added, regardless if mCellYTop * becomes bigger than mCellYBottom, this is useful when * moving items because it guarantees expandTop and the * following expandBottom call add the same value. */ void expandTop( int dy, const bool allowOverLimit = false ); void expandBottom( int dy ); void expandLeft( int dx ); void expandRight( int dx ); bool isMultiItem() const; AgendaItem::QPtr prevMoveItem() const { return (mStartMoveInfo) ?
