KisTransformUtils::AnchorHolder Struct Reference

#include <kis_transform_utils.h>

Public Member Functions
	AnchorHolder (bool enabled, ToolTransformArgs *config)
	~AnchorHolder ()

Private Attributes
ToolTransformArgs *	m_config
bool	m_enabled
QPointF	m_oldStaticPointInView
QPointF	m_staticPoint

Detailed Description

A special class that ensures that the view position of the anchor point of the transformation is unchanged during the lifetime of the object. On destruction of the keeper the position of the anchor point will be restored.
