Java Swing Designer-AI Swing GUI Builder

Example

From an interactive canvas the Designer lays out components with proper layout managers, groups related controls into reusable JPanel components, and generates compact, readable Java code that follows Swing conventions: initializing components on the Event Dispatch Thread, using layout managers instead of absolute positioning, and exposing well-documented hooks for controller/model injection. Generated artifacts include a JPanel subclass per view, a resource folder for icons and strings, and a small factory or builder for creating the view with dependency injection.

Scenario

A mid-sized application needs a login dialog. The Designer builds a LoginPanel with username and password fields arranged in GridBagLayout, a login button wired to an ActionListener stub, and safe password handling. It outputs LoginPanel.java plus a LoginController interface and a test skeleton. The developer drops generated files into the project, implements authentication logic in the controller, and gets a functioning dialog that follows best practices for thread-safety and separation of concerns.

Example

The Designer scaffolds model and controller interfaces, a TableModel for tabular data, property change support, and binding helpers that map model fields to form fields. It can generate a SwingWorker based template for long-running tasks, and it wires events so that model changes update the view and user actions call controller methods.

Scenario

An inventory management screen needs to load thousands of rows from a database. The Designer generates: InventoryTableModel that implements AbstractTableModel, a Controller with async loadData method implemented using SwingWorker, and a View that displays a progress bar while loading. The Controller returns results on the EDT and the view updates through TableModel events. This prevents the UI from freezing and keeps concerns separated, which makes unit testing controllers straightforward and keeps the view code minimal.

Example

The Designer integrates look and feel options (for example FlatLaf or the system LAF), generates accessible component metadata like accessible names and descriptions, uses ResourceBundle patterns for localization, and produces unit-testable code with hooks for mocking UI events. It also generates build artifacts or instructions for Maven/Gradle integration and can export design assets (icons, CSS-like theme variables) so the app appearance is consistent.

Scenario

A healthcare application must be accessible and localized to three languages. The Designer produces UI code where each visible string is loaded from a properties file, each input has an accessible name and tooltip, and theming variables allow the QA team to switch contrast and font-size for accessibility testing. It also generates a small test that asserts critical components have accessible names and that the correct resource keys exist, helping QA and compliance reviews.
