Package-level declarations

Types

component operations represent simple procedures that are ran before and after every render cycle. They can support animations and verification.

class Fade<S : Drawable>(drawable: S, alpha: Float, add: Boolean = true, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

class KeyFrame(val start: Float, prev: KeyFrame?)

annotation class KeyFrameDSL

marker class for preventing illegal nesting.

Keyframes are an easy way to create animations on components. PolyUI uses a Kotlin DSL to create them in an easy and concise way.

class Move<S : Component>(drawable: S, x: Float = drawable.x, y: Float = drawable.y, add: Boolean = true, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

class Recolor<S : Drawable>(drawable: S, toColor: PolyColor, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

Changes the color of the component to the specified color. Supports animation and callback function on finish.

class Resize<S : Component>(drawable: S, width: Float = drawable.width, height: Float = drawable.height, add: Boolean = true, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

class Rotate<S : Drawable>(drawable: S, angleRad: Double, add: Boolean = true, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

class Scale<S : Drawable>(drawable: S, scaleX: Float, scaleY: Float, add: Boolean = true, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

class ShakeOp<S : Component>(drawable: S, durationNanos: Long, oscillations: Int, range: Float = 4.0f, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

class Skew<S : Drawable>(drawable: S, skewX: Double, skewY: Double, add: Boolean = true, animation: Animation? = null, onFinish: S.() -> Unit? = null) : ComponentOp.Animatable<S>

fun <S : Drawable> S.keyframed(animation: Animation, frames: KeyFrames<S>.() -> Unit)

create a keyframe set for this component.
