Write Swing desktop UIs with the SwingTree library and its companion property library Sprouts. Use this skill whenever you are building, editing, reviewing, or debugging Java Swing GUI code that imports `swingtree.UI` or `sprouts.*` — declarative component trees, MigLayout/responsive/reactive layouts, the functional style API, SVG icons, animations, and MVI/MVL or MVVM view models.
