void	addGroupPositionUndo (QGraphicsItem *item, const QPointF &pivot, qreal angle)
	RotateSelectionCommand::addGroupPositionUndo Queue a "pos" QPropertyUndoCommand that rotates item's position around pivot by angle degrees (Qt's clockwise-positive convention, matching QGraphicsItem::setRotation() so a group rotation turns the same direction as each item's own spin). Only meaningful for items whose pos() is in scene coordinates (Element, IndependentTextItem, DiagramImageItem) – never call this for a child item positioned relative to its own parent.

Member Function Documentation

addGroupPositionUndo()

void RotateSelectionCommand::addGroupPositionUndo ( QGraphicsItem * item, const QPointF & pivot, qreal angle )

private

RotateSelectionCommand::addGroupPositionUndo Queue a "pos" QPropertyUndoCommand that rotates item's position around pivot by angle degrees (Qt's clockwise-positive convention, matching QGraphicsItem::setRotation() so a group rotation turns the same direction as each item's own spin). Only meaningful for items whose pos() is in scene coordinates (Element, IndependentTextItem, DiagramImageItem) – never call this for a child item positioned relative to its own parent.

Parameters

item	: item to reposition, its own rotation undo already queued
pivot	: shared pivot point, in scene coordinates
angle	: rotation angle in degrees
