Private Attributes
KisImageWSP	m_image
int	m_removedNodeIndex
KisNodeSP	m_removedNodeParent
QRect	m_updateRect

Detailed Description

Used for performing the smallest update after a node has been removed from stack. First tries to setDirty() node's siblings. If it doesn't help, performs full refresh.

UpdateTarget()

KisImageCommand::UpdateTarget::UpdateTarget	(	KisImageWSP	image,
		KisNodeSP	removedNode,
		const QRect &	updateRect )

We are saving an index, but not shared pointer, because the target node may suddenly reincarnate into another type of a layer during the removal process

    m_removedNodeIndex = m_removedNodeParent ? m_removedNodeParent->index(removedNode) : -1;
