This version holds true to the core concepts of echo by NextApp, Inc. while providing dramatic performance, capability, and user-experience enhancements made possible by its new Ajax-based rendering engine.
Echo 2.1.1 / 3.0.beta8 removes the developer from having to think in terms of "page-based" applications and enables him/her to develop applications using the conventional object-oriented and event-driven paradigm for user interface development. Knowledge of HTML, HTTP, and javascript is not required.
Most important functions of Echo [echo2.1.1 / 3.0.beta8.exe]:
• Class-based JavaScript Inheritance: The Echo - 0MB3 Core. JS module provides the capability to use class-based (rather than instance-based) inheritance in JavaScript.
• Abstract JavaScript Properties: The Core. JS system of class definition allows for the declaration of abstract method, ensuring concrete implementations define them.
• Virtual and Final JavaScript Properties: The class definition system enables JavaScript properties to be declared as either virtual or final, thus allowing reservation of property names and preventing derived classes from overriding internal variables found in base classes.
• Method references: The Echo 2.1.1 / 3.0.beta83 Core JS module defines a concept of "method references" for callbacks which are used throughout the client-side framework. Method references can be used when registering event listeners on components, dom elements, and arbitrary script objects such that generated events will be fired to a method of a specific object instance.
• DOM Event Processor: All DOM events are now handled by the Echo3 DOM event processor, enabling the use of capturing event listeners on all platforms (Internet Explorer does not natively support capturing listeners).
• Scheduler: The Echo3 Core JS module provides a window. setTimeout/Interval()-based scheduling system to invoke tasks repeatedly, after a delay, or after the current JavaScript context has completed. The scheduler supports method references, such that methods may be invoked on specific objects.
• Keyboard Navigation / Focus Management: Focus amongst components is now fully tracked. Echo does away with the practice of using sequential tab index numbers to control focus order, instead presenting next/previous element focus events to components for a more intuitive user interface. Components that have multiple "focus points" especially benefit from this feature.
• Off-screen Rendering: Infrastructure is available to provide off-screen rendering to the DOM, such that sizing calculations may be performed on rendered HTML before placing it onscreen. This method is used by the WindowPane component, for example, to automatically size title bar height.
