void	hideNotification ()
void	requestNotification (const QModelIndex &index, const QString &message)

Public Member Functions
	ItemDelegateOverlay (QObject *const parent=nullptr)
virtual bool	acceptsDelegate (QAbstractItemDelegate *) const
QAbstractItemDelegate *	delegate () const
virtual void	mouseMoved (QMouseEvent *e, const QRect &visualRect, const QModelIndex &index)
	Only these two methods are implemented as virtual methods.
virtual void	paint (QPainter *p, const QStyleOptionViewItem &option, const QModelIndex &index)
virtual void	setActive (bool active)
	Called when the overlay was installed and shall begin working, and before it is removed and shall stop.
void	setDelegate (QAbstractItemDelegate *delegate)
void	setView (QAbstractItemView *view)
QAbstractItemView *	view () const

Protected Slots
virtual void	visualChange ()
	Called when any change from the delegate occurs - when the overlay is installed, when size hints, styles or fonts change.

Protected Member Functions
QList< QModelIndex >	affectedIndexes (const QModelIndex &index) const
bool	affectsMultiple (const QModelIndex &index) const
	For the context that an overlay can affect multiple items: Assuming the currently overlaid index is given.

bool	viewHasMultiSelection () const
	Utility method.

Protected Attributes
QAbstractItemDelegate *	m_delegate = nullptr
QAbstractItemView *	m_view = nullptr

Member Function Documentation

affectsMultiple()

bool Digikam::ItemDelegateOverlay::affectsMultiple ( const QModelIndex & index ) const

protected

Will an operation affect only the single item, or multiple? If multiple, retrieve the affected selection.

mouseMoved()

void Digikam::ItemDelegateOverlay::mouseMoved ( QMouseEvent * e, const QRect & visualRect, const QModelIndex & index )

virtual

For all other events, connect to the view's signals. There are a few signals specifically for overlays and all QAbstractItemView standard signals.

setActive()

void Digikam::ItemDelegateOverlay::setActive ( bool active )

virtual

Setup your connections to view and delegate here. You will be disconnected automatically on removal.
