Constructor & Destructor Documentation

§ IlvGraphicAnimator()

IlvGraphicAnimator::IlvGraphicAnimator ( IlSymbol name,
IlvAnimationMode  mode = IlvAnimationForward,
IlUInt  period = 100,
IlBoolean  useApply = IlTrue 
)

Constructor.

Initializes a new instance of the IlvGraphicAnimator class. The animator will start when it is connected to any object.

Parameters
nameThe animator name.
modeThe animation mode.
periodThe animator period.
useApplyA Boolean value specifying whether the animator will use "applyToObject" functions.

Member Function Documentation

§ addTo()

void IlvGraphicAnimator::addTo ( IlvGraphic graphic)

Connects the animator with a given graphic object.

Does nothing if the graphic object already has a named property with the same symbol as this.

Parameters
graphicThe graphic object.
See also
GetAnimator(), removeFrom()

§ animate()

virtual void IlvGraphicAnimator::animate ( )
virtual

Called to animate the animator.

The default implementation calls IlvAnimator::changeState with the result of IlvAnimator::nextState as new state, and with redraw set to IlTrue.

See also
getState(), nextState(), setState(), changeState()

Reimplemented from IlvAnimator.

§ Get()

static IlvGraphicAnimator* IlvGraphicAnimator::Get ( const IlvGraphic graphic,
const IlSymbol name 
)
static

Returns the animator connected with a graphic object given its name.

Parameters
graphicThe graphic object.
nameThe animator name.
Returns
The animator named name connected with graphic.
See also
addTo(), removeFrom()

§ getGraphic()

IlvGraphic* IlvGraphicAnimator::getGraphic ( ) const

Returns the graphic object connected with the animator.

Returns
The graphic object connected with this animator.

§ initReDraws()

virtual void IlvGraphicAnimator::initReDraws ( ) const
virtual

Called to begin a redraw session.

You must redefine this method in a subclass.

See also
reDraw(), invalidateRegion(), reDrawViews()

Implements IlvAnimator.

§ invalidateRegion()

virtual void IlvGraphicAnimator::invalidateRegion ( ) const
virtual

Called to invalidate the area affected by the animator.

You must redefine this method in a subclass.

See also
reDraw(), initReDraws(), reDrawViews()

Implements IlvAnimator.

§ reDrawViews()

virtual void IlvGraphicAnimator::reDrawViews ( ) const
virtual

Called to finish a redraw session.

You must redefine this method in a subclass.

See also
reDraw(), initReDraws(), invalidateRegion()

Implements IlvAnimator.

§ removeFrom()

void IlvGraphicAnimator::removeFrom ( IlvGraphic graphic)

Disconnects the animator from the given graphic object.

Parameters
graphicThe graphic object.
See also
GetAnimator(), addTo()

§ RemoveFrom()

static IlvGraphicAnimator* IlvGraphicAnimator::RemoveFrom ( IlvGraphic graphic,
const IlSymbol name 
)
static

Removes the menu item group from the specified abstract menu.

Parameters
graphicThe abstract menu.
nameThe group name.
See also
Get(), addTo()

§ stateChanged()

virtual void IlvGraphicAnimator::stateChanged ( IlUInt  newState,
IlUInt  oldState 
)
virtual

Called by IlvAnimator::changeState each time the animator state changes.

The default implementation does nothing.

Parameters
newStateThe new animator state.
oldStateThe previous animator state.
See also
getState(), nextState(), changeState()

Reimplemented from IlvAnimator.

§ useApply()

void IlvGraphicAnimator::useApply ( IlBoolean  value)

Specifies to the animator whether to use "applyTo" functions.

See the description of IlvAnimator::useApply for more details.

See also
IlvGraphicHolder::applyToObject, useApply()

§ usesApply()

IlBoolean IlvGraphicAnimator::usesApply ( ) const

Returns a Boolean indicating whether the animator will use "applyToObject" functions.

The default value for this setting is IlTrue. It means that the animate call is encapsulated in a call to IlvGraphicHolder::applyToObject. This makes it possible to move the graphic object encapsulated in this animator without calling applyToObject yourself. However, if you know that the animator will not move the object, you can disable this feature to improve performance.

Returns
A Boolean indicating whether the animator will use "applyToObject" functions.

IlvGraphicHolder::applyToObject, useApply()
