Description

Apply animation effects to components and windows. Inspired by script.aculo.us effects.

Installation

The current version of griffon-effects-plugin is 0.4
To install just issue the following command

griffon install-plugin effects

Usage

Effects can be applied in two ways:

• create a new Effect instance and run it.
• use the convenience methods exposed by griffon.effects.Effects (each method matches the effect's name in lower case, Move => Effects.move)

Every effect takes the following parameters:

• component - the component to be animated
• params - a map with effect options, may be empty or null
• callback - a closure to be called at the end of the effect, optional.

All effects share the following options unless otherwise specified:

• duration - ong, how long should the animation take. default: 500l
• delay - long, wait time before the animation starts. default: 0l
• ease - TimelineEase. default: Linear
• wait - boolean. Forces the current thread to wait until the effect has finished running default: false

Some effects accept an anchor option, whose value is defined by the griffon.effects.Anchor enum. Additional valid values are string literals in lower case, with underscores substituted by spaces; literals from SwingConstants are also valid. Examples

• Anchor.TOP == 'top' == 'TOP' == 'NORTH' == 'north
• Anchor.TOP_LEFT == 'top left == 'top_left' == 'NORTH EAST' == 'north east'

Basic Effects

Move

Animates the location property of the target component
Parameters:

• x - int, in pixels. default: 0i
• y - int, in pixels. default: 0i
• mode - String, if movement should be 'relative' or 'absolute'. default: 'relative'

Resize

Animates the size property of the target component
Parameters:

• w - int, in pixels. default: 0i
• h - int, in pixels. default: 0
• mode - String, if the update should be 'relative' or 'absolute'. default: 'relative'

Bounds

Animates the bounds property of a the target component
Parameters:

• x - int, in pixels. default: 0i
• y - int, in pixels. default: 0i
• w - int, in pixels. default: 0i
• h - int, in pixels. default: 0
• mode - String, if the update should be 'relative' or 'absolute'. default: 'relative'

Scale

Animates the bounds property of the target component by calculating a scale factor
Parameters:

• scaleX - boolean, if the x coorinate should scale. default: true
• scaleY - boolean, if the y coorinate should scale. default: true
• from - float, starting value in percentage. default: 100.0f
• to - float, ending value in percentage. default: 0.0f
• anchor - Anchor, anchoring point. default: Anchor.CENTER

Opacity

Animates a window's opacity property
Parameters:

• from - float, starting value. default: 0.0f
• to - float, ending value. default: 1.0f

Fade

Animates a window's opacity from its current value or 1.0f to 0.0f

Appear

Animates a window's opacity from its current value or 0.0f to 1.0f

Composite Effects

Shake

Moves a component from right to left a few times
Parameters:

• distance - int, in pixels. default: 20i

Puff

Fades and blows up a window

DropOut

Fades and moves a window out of the screen
Paremeters:

• anchor - Anchor, anchoring point. default: Anchor.BOTTOM

DropIn

Appears and moves a window to the center of the screen
Paremeters:

• anchor - Anchor, anchoring point. default: Anchor.TOP
