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().
