Interactor to move or resize graphic objects.
Library: views
Combines the two interactors IlvMoveInteractor
and IlvReshapeInteractor
.

. virtual void IlvMoveReshapeInteractor::getCallbackTypes | ( | IlUInt & | count, | |
const char *const ** | names, | |||
const IlSymbol *const ** | types | |||
) | const [virtual] |
Gets the number of register callback types for the interactor.
If you provide a non-0
pointer to an array of strings in the parameter names, it is set on return to point to an array of strings that describe each of the callback types. Some of these descriptions may be 0
. You must not modify nor delete this array. If you provide a non-0
pointer to an array of symbols in the parameter types, it is set on return to point to an array of symbols that define each of the callback types. You must not modify nor delete this array. If you create a new callback type and want it returned by a call to getCallbackTypes
, you can use the static member function IlvGraphic::AddToCallbackTypeList
. The default implementation registers one callback with the shared name of the interactor as symbol. For example, the IlvMoveInteractor
class has a callback registered on the symbol "Move".
count | The number of elements in the returned arrays names and types. This parameter must be set to 0 before calling this method. | |
names | An array of strings. | |
types | An array of symbols. |
Reimplemented from IlvInteractor.
virtual IlBoolean IlvMoveReshapeInteractor::handleEvent | ( | IlvGraphic * | g, | |
IlvEvent & | event, | |||
const IlvTransformer * | t | |||
) | [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.
