Public Member Functions
	HidingStateChanger (QObject *const parent=nullptr)
	This class provides a state change while fading in and out: When changeValue is called, first the items are hidden, when this is finished, the property is assigned to the object.
	HidingStateChanger (QObject *const target, const QByteArray &property, QObject *const parent=nullptr)
	Convenience constructor: Sets target and property name.
void	setPropertyName (const QByteArray &propertyName)
void	setTargetObject (QObject *const object)
Public Member Functions inherited from Digikam::ItemVisibilityController
	ItemVisibilityController (QObject *const parent=nullptr)
void	addItem (QObject *const object)
	Add and remove objects.
void	clear ()
	Remove all animations.
bool	hasVisibleItems (IncludeFadingOutMode mode=IncludeFadingOut) const
bool	isVisible () const
QList< QObject * >	items () const
void	removeItem (QObject *const object)
void	setAnimationDuration (int msecs)
void	setEasingCurve (const QEasingCurve &easing)
	Allows to change the default parameters of all animations.
bool	shallBeShown () const
State	state () const
QList< QObject * >	visibleItems (IncludeFadingOutMode mode=IncludeFadingOut) const

Afterwards, the items are shown again. Note that the targetObject is not necessarily a controlled item!
