Manager interactor class.
Library: views
The IlvMoveInteractor
class lets the user move an object by dragging it.
The registered name of this interactor is "Move".
IlvReshapeInteractor
, IlvMoveReshapeInteractor
.
|
virtual |
Finalizes the interaction by moving the object.
Called to move the object to a new position. After moving the object, this method calls the object's callback corresponding to the Move symbol.
object | The graphic object. |
deltaMove | The difference between the new and the initial location of the object in the object coordinate system. |
t | The transformer applied to the view. |
IlvGraphic::setCallback()
|
virtual |
Visual feedback during the interaction.
Called to draw a preview image of the resulting user action. It is generally invoked by handleEvent()
as a response to user events.
view | The view where the object is displayed. |
ghost | The graphic object used as ghost image. |
deltaMove | The difference between the current and the initial location of the object in view coordinates. |
t | The transformer applied to the view. |
|
virtual |
Performs the actions needed when the interaction ends.
The default implementation resets the interactor flags and remove it from its parent, if it exists.
IlvStackInteractorInterface::removeFromParent()
. Reimplemented from IlvInteractor.
|
virtual |
Handles events received by the interactor.
This method is the entry point of all events dispatched to this interactor.
g | The graphic object that receives the event. |
event | The received event. |
t | The transformer applied to the view in which the event occurred. |
IlTrue
if the event was successfully handled and IlFalse
otherwise. Implements IlvInteractor.
|
virtual |
Lets you modify intermediate positions during the interaction.
Called for each mouse movement so that the user can modify the object position. When the mouse button is released, doIt()
is called.
object | The considered graphic object. |
p | The current position, in the object coordinate system. |
t | The transformer applied to the view. |
