swing-ui-animation

The animation engine for Compose Swing UI. It provides the familiar Compose animation APIs - animate*AsState, Animatable, updateTransition / Transition, rememberInfiniteTransition, easing curves (including CubicBezierEasing), and the spring / tween / keyframes specs - for the Float, Int, and generic (TwoWayConverter) value types.

Usage

Animations run with no extra wiring inside a setContent { ... } composition: they are driven by the window's frame clock automatically, advancing at the display's refresh rate while an animation is in flight and resting otherwise.

import org.jetbrains.compose.swing.animation.core.animateFloatAsState
import androidx.compose.runtime.getValue

val alpha by animateFloatAsState(if (visible) 1f else 0f)

For value types beyond Float / Int, supply a TwoWayConverter (e.g. to animate java.awt.Color). The animation APIs are documented in KDoc.
