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 current movement 3: endMovement -> finish the current movement

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

Member Function Documentation

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.

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.

isReady()

bool ElementsMover::isReady

(

)

const

ElementsMover::isReady.

Returns

True if this element mover is ready to be used. A element mover is ready when the previous managed movement is finish.
