Detailed Description

This class manages the interactive movement of different items (elements, conductors, text items etc...) on a particular diagram.

A movement work in 3 steps: 1: beginMovement -> init a new movement 2: continueMovement -> continue the curent movement 3: endMovement -> finish the curent movement

A movement in progress must finish befor start a new movement. We can know if element mover is ready for a new movement by calling isReady().

◆ beginMovement()

int ElementsMover::beginMovement	(	Diagram *	diagram,
		QGraphicsItem *	driver_item = `nullptr`
	)

ElementsMover::beginMovement Start a new movement.

Parameters

diagram	diagram where the movement is applied
driver_item	item moved by mouse and don't be moved by Element mover

Returns: the numbers of items to be moved or -1 if movement can't be init.

◆ continueMovement()

void ElementsMover::continueMovement ( const QPointF & movement )

ElementsMover::continueMovement Add a move to the current movement.

Parameters

◆ endMovement()

void ElementsMover::endMovement ( )

ElementsMover::endMovement Ended the current movement by creating an undo added to the undostack of the diagram. If there is only one element moved, we try to auto-connect new conductor from this element and other possible element.
