affectsMultiple()

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

Only these two methods are implemented as virtual methods. 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

Called when the overlay was installed and shall begin working, and before it is removed and shall stop. Setup your connections to view and delegate here. You will be disconnected automatically on removal.
