JavaFX Patterns for Xeres

Controller Structure

Controllers are Spring components with FXML views:

@Component
@FxmlView(value = "/view/contact/contact_view.fxml")
public class ContactViewController implements Controller
{
	@FXML
	private TreeTableView<Contact> contactTreeTableView;

	@Override
	public void initialize()
	{ ...}
}

Window Controllers

For windows/dialogs, implement WindowController interface:

@Component
@FxmlView(value = "/view/settings/settings_window.fxml")
public class SettingsWindowController implements WindowController
{

	@Override
	public void onShowing()
	{ ...}

	@Override
	public void onShown()
	{ ...}

	@Override
	public void onClose()
	{ ...}
}

Naming convention: *WindowController

Window Management

Use WindowManager for window lifecycle.

JavaFX-App Integration

public class JavaFxApplication extends Application
{
	private ConfigurableApplicationContext springContext;

	@Override
	public void init()
	{
		springContext = new SpringApplicationBuilder()
				.sources(springApplicationClass)
				.headless(false)
				.initializers(initializers())
				.run(getParameters().getRaw().toArray(new String[0]));
	}
}

File Choosers

Never call FileChooser.setInitialDirectory() directly. Use ChooserUtils:

// Bad
fileChooser.setInitialDirectory(someDirectory);

// Good
ChooserUtils.

setInitialDirectory(fileChooser, someDirectory);

FXML Location Convention

ui/src/main/resources/view/<feature>/<feature>_view.fxml
ui/src/main/resources/view/<feature>/<feature>_window.fxml (for dialogs)

Binding Patterns

Use JavaFX properties for observable data:

private final StringProperty nameProperty = new SimpleStringProperty();
private final ObjectProperty<Profile> selectedProfile = new SimpleObjectProperty<>();

UI Event Handling

Dispatch events through Spring's ApplicationEventPublisher:

public record ContactSelectedEvent(Contact contact)
{
}
