Class MorphTransition

java.lang.Object

com.codename1.ui.animations.Transition

com.codename1.ui.animations.MorphTransition

All Implemented Interfaces:

Animation

public class MorphTransition
extends Transition

A transition inspired by the Android L release morph activity effect allowing a set of components in one form/container to morph into another in a different container/form.

Method Summary

Modifier and Type	Method and Description
boolean	animate() Allows the animation to reduce "repaint" calls when it returns false.
Transition	copy(boolean reverse) Create a copy of the transition, usually the transition used is a copy.
static MorphTransition	create(int duration) Creates a transition with the given duration, this transition should be modified with the builder methods such as morph
void	initTransition() Callback thats invoked before a transition begins, the source form may be null for the first form in the application.
MorphTransition	morph(String cmp) Morphs the component with the given source name in the source container hierarchy to the component with the same name in the destination hierarchy
MorphTransition	morph(String source, String to) Morphs the component with the given source name in the source container hierarchy to the component with the given name in the destination hierarchy
void	paint(Graphics g) Draws the animation, within a component the standard paint method would be invoked since it bares the exact same signature.

Method Detail

copy

public Transition copy(boolean reverse)

Create a copy of the transition, usually the transition used is a copy.

Overrides:

copy in class Transition

Parameters:

reverse - creates a new transition instance with "reverse" behavior useful for signifying "back" operations

Returns:

new transition instance

create

public static MorphTransition create(int duration)

Creates a transition with the given duration, this transition should be modified with the builder methods such as morph

Parameters:

duration - the duration of the transition

Returns:

a new Morph transition instance

morph

public MorphTransition morph(String cmp)

Morphs the component with the given source name in the source container hierarchy to the component with the same name in the destination hierarchy

Parameters:

cmp - the compoennt name

Returns:

this so morph operations can be chained as MorphTransition t = MorphTransition.create(300).morph("a").("c");

morph

public MorphTransition morph(String source,
                             String to)

Morphs the component with the given source name in the source container hierarchy to the component with the given name in the destination hierarchy

Parameters:

source -

to -

Returns:

this so morph operations can be chained as MorphTransition t = MorphTransition.create(300).morph("a", "b").("c", "d");

initTransition

public final void initTransition()

Callback thats invoked before a transition begins, the source form may be null for the first form in the application.

Overrides:

initTransition in class Transition

animate

public boolean animate()

Allows the animation to reduce "repaint" calls when it returns false. It is called once for every frame. Frames are defined by the Display class.

Specified by:

animate in interface Animation

Specified by:

animate in class Transition

Returns:

true if a repaint is desired or false if no repaint is necessary

paint

public void paint(Graphics g)

Draws the animation, within a component the standard paint method would be invoked since it bares the exact same signature.

Specified by:

paint in interface Animation

Specified by:

paint in class Transition

Parameters:

g - graphics context
