The UI Builder subsystem provides a comprehensive environment for visual application development. The UIBuilderApp acts as the central hub, coordinating various specialized components. The Canvas/Design Surface offers the interactive visual workspace, while the Properties Panel and Widget Palette/Library Integration facilitate widget configuration and selection. Data and event logic are managed through the Data Binding Editor and Action/Event Editor, respectively, which integrate with external execution engines. All design-time changes are consistently managed by the Application State Manager, ensuring a coherent representation of the application. Finally, the Save/Load Manager handles the persistence of the entire application definition by interacting with a backend API Gateway. This architecture ensures a clear separation of concerns, allowing for modular development and efficient management of the UI building process.
The central orchestrator of the UI building process. It initializes and manages the lifecycle of the design canvas, property panels, and various editors, delegating tasks to specialized internal components.
