JavaFX Scene Builder

Purpose-built for JavaFX development teams, this tool converts UI requirements or existing FXML into consistent, ready-to-use artifacts. It analyzes the target root layout, maps components to JavaFX controls, and outputs generated_fxml, recommended_css, and optional controller_stubs. Conceptually, it treats the UI as a layout graph, assigns layout constraints, and applies standard JavaFX styling hooks that Scene Builder can import. This enables rapid prototyping, refactoring, and cross-version validation. The tool is valuable to developers, UI designers, and educators who need repeatable scaffolding without manual code typing. The core differentiators are its explicit separation of layout logic from styling hints, version-aware control mapping, and structured outputs that align with Scene Builder workflows. Use cases include starting a new JavaFX project from a textual specification, converting a hand-drawn layout into FXML, and producing CSS snippets that adapt to different root panes. Outputs are designed to be importable into Scene Builder or IDEs, with controller_stubs ready for basic event handling. The tool emphasizes deterministic layout generation, clear error signaling for invalid inputs, and support for common layouts like GridPane, VBox, and BorderPane. Advanced users can leverage the outputs as a baseline for localization scaffolding and accessibility attributes, while keeping the UI description as the canonical source of truth.
