Member Function Documentation

cancelMove()

virtual QRect MoveNodeStrategyBase::cancelMove ( )

pure virtual

Implemented in MoveNormalNodeStrategy, MoveTransformMaskStrategy, and MovePaintableNodeStrategy.

finishMove()

virtual void MoveNodeStrategyBase::finishMove ( KUndo2Command * parentCommand )

pure virtual

Implemented in MoveNormalNodeStrategy, MoveTransformMaskStrategy, and MovePaintableNodeStrategy.

moveNode()

virtual QRect MoveNodeStrategyBase::moveNode ( const QPoint & offset )

pure virtual

Implemented in MoveNormalNodeStrategy, MoveTransformMaskStrategy, and MovePaintableNodeStrategy.

moveNodeCommon()

QRect MoveNodeStrategyBase::moveNodeCommon ( const QPoint & offset )

inlineprotected

Some layers, e.g. clones need an update to change extent(), so calculate the dirty rect manually
