setTarget()

void ItemBackground::setTarget

(

const QRectF &

newGeometry

)

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

Parameters

newGeometry

the final geometry target

Definition at line 106 of file itembackground.cpp.

setTargetItem()

void ItemBackground::setTargetItem

(

QGraphicsItem *

target

)

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

Definition at line 142 of file itembackground.cpp.

target()

QRectF ItemBackground::target

(

)

const

Returns

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

Definition at line 101 of file itembackground.cpp.

targetItem()

QGraphicsItem * ItemBackground::targetItem

(

)

const

Returns

the target item, if any

Definition at line 198 of file itembackground.cpp.

targetItemReached

void Plasma::ItemBackground::targetItemReached ( QGraphicsItem * )

signal

Emitted when the target has been reached.

Useful to consider this instead of the corresponding hoverEnterEvent;

targetReached

void Plasma::ItemBackground::targetReached ( QRectF )

signal

Emitted when the target has been reached.

Useful to consider this instead of the corresponding hoverEnterEvent;
