Detailed Description

Named property class.

Library: views

IlvGraphicAnimator is a subclass of IlvAnimator that deals with animation of IlvGraphic objects.

See also: IlvBitmapAnimator

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

name	The animator name.
mode	The animation mode.
period	The animator period.
useApply	A 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

graphic The 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

graphic	The graphic object.
name	The 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

graphic The 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

graphic	The abstract menu.
name	The 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

newState	The new animator state.
oldState	The 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.
