)

Member Function Documentation

void IlvRotateInteractor::abort ( )
virtual

Aborts the interaction.

Called by the manager when the user changes the current interactor. It resets the interactor to a state in which it appears to have never been launched. A common implementation is to erase the ghost image. Call this member function to inhibit the interactor action in particular circumstances.

Reimplemented from IlvManagerViewInteractor.

virtual void IlvRotateInteractor::doIt ( IlFloat  angle)
virtual

Finalizes the interaction by rotating the selected objects.

In the default implementation, rotates selected objects by an amount specified in the parameter angle The center of the rotation is the center of the bounding box of the selected objects.

Parameters
angleThe rotation angle, in degrees.
void IlvRotateInteractor::drawGhost ( )
virtual

Visual feedback during the interaction.

Called to draw a preview image of the resulting user action (the ghost image of the interactor). This function is generally invoked by IlvManagerViewInteractor::handleEvent as a response to user events.

Reimplemented from IlvManagerViewInteractor.

void IlvRotateInteractor::handleEvent ( IlvEvent event)
virtual

Handles events for the manager view.

Called by the manager for which the interactor was created with every event it receives in the interactor view.

Implements IlvManagerViewInteractor.

void IlvRotateInteractor::init ( )
virtual

Initialization, when the interactor is attached to a view.

Resets the interactor to its initial state.
Called by the manager whenever the interactor is associated with a view. An association of this kind is established by the member function IlvManager::setInteractor.

Reimplemented from IlvManagerViewInteractor.
