Gled 1.2.5

Gled is a C++ framework for rapid development of applications with support for GUI (using FLTK), 3D-graphics and distributed computing. It extends the ROOT framework (standard data-analysis tool in high-energy physics) with mechanisms for object collection management & serialization, multi-threaded execution, GUI auto-generation (object browser & editor) and dynamic visualization (OpenGL).

Distributed computing model of Gled is a hierarchy of nodes connected via TCP/IP sockets. Gled provides authentication & access control, data exchange, proxying of object collections and remote method-call propagation & execution.

Gled can be dynamically extended with library sets. Their creation is facilitated by a set of scripts for creation of user-code stubs. Simple tasks and application configuration can be efficiently done via the interactive C++ interpreter (CINT).

Gled is used for development of programs in high energy physics and as a research tool in distributed and grid computing.

GUI features:

• auto-generated object control widgets presenting controls for all exported object members variables, methods and aggregation-facilites (object-pointers and containers)
• browser for arbitrary object graphs with editing facilities and drag-and-drop support
• integrated mechanisms for (remote) object instantiation
• object context-menu for browsing & execution of (remote) method invocation requests
• GUI control over server-client-viewer system and clustering (using Gled introspection where server-client tree is represented as a Gled object graph)
• zoom control for all fonts and widgets (laptop-friendly)
