void Plasma::ItemBackground::appearanceChanged

(

)

[signal]

Emitted when the visual layout and appearance changes.

Useful for synchronizing content margins.

bool ItemBackground::eventFilter	(	QObject *	watched,
		QEvent *	event
	)		[protected]

Reimplemented from superclass. from QObject

Definition at line 204 of file itembackground.cpp.

QVariant ItemBackground::itemChange	(	GraphicsItemChange	change,
		const QVariant &	value
	)		[protected]

Reimplemented from superclass. from QGraphicsWidget

Definition at line 236 of file itembackground.cpp.

void ItemBackground::paint	(	QPainter *	painter,
		const QStyleOptionGraphicsItem *	option,
		QWidget *	widget
	)

Definition at line 264 of file itembackground.cpp.

void ItemBackground::resizeEvent

(

QGraphicsSceneResizeEvent *

)

[protected]

Reimplemented from superclass. from QGraphicsItem

Definition at line 231 of file itembackground.cpp.

bool ItemBackground::sceneEventFilter	(	QGraphicsItem *	watched,
		QEvent *	event
	)		[protected]

Reimplemented from superclass. from QGraphicsItem

Definition at line 220 of file itembackground.cpp.

void ItemBackground::setTarget

(

const QRectF &

newGeometry

)

Sets a new target geometry we want at the end of animation.

• newGeometry the final geometry target

Definition at line 107 of file itembackground.cpp.

void ItemBackground::setTargetItem

(

QGraphicsItem *

target

)

set the ItemBackground geometry to be the target geometry, plus the ItemBackground margins

Definition at line 143 of file itembackground.cpp.

QRectF Plasma::ItemBackground::target

(

)

const

Returns:

the current target rect; may be empty if there is no target currently set

QGraphicsItem* Plasma::ItemBackground::targetItem

)

const

Returns:

the target item, if any

void Plasma::ItemBackground::targetItemReached

(

QGraphicsItem *

)

[signal]

Emitted when the target has been reached.

Useful to consider this instead of the corresponding hoverEnterEvent;

QRectF

)

[signal]

Emitted when the target has been reached.

Useful to consider this instead of the corresponding hoverEnterEvent;
