Member Function Documentation

virtual IlBoolean IlvSelectorInteractor::accept ( const IlvGraphic *  obj ) const

virtual

Indicates whether the current interactor can be associated with a given object.

Parameters

obj	The considered graphic object.

Returns

IlTrue if the interactor can safely be attached to obj, and IlFalse otherwise.

See also

IlvGraphic::setInteractor().

Reimplemented from IlvInteractor.

virtual void IlvSelectorInteractor::doIt ( IlvSelector *  selector )

protectedvirtual

Called when objects are selected or deselected.

Called when an item of the selector is selected or deselected. The user can check the selector object to find out what has been modified. The default implementation calls the callback of selector if it exists.

Parameters

selector

The selector object.

virtual IlBoolean IlvSelectorInteractor::handleEvent ( IlvGraphic *  g, IlvEvent &  event, const IlvTransformer *  t = 0  )

virtual

Handles events received by the interactor.

This method is the entry point of all events dispatched to this interactor.

Parameters

g	The graphic object that receives the event.
event	The received event.
t	The transformer applied to the view in which the event occurred.

Returns

IlTrue if the event was successfully handled and IlFalse otherwise.

Implements IlvInteractor.
