GLG Toolkit, Java Class Library.

This JavaDoc-style documentation provides a list of GLG classes and methods and is intended to serve only as a quick reference. Refer to the GLG documentation for details of the GLG Toolkit and its usage.

Overview

The GLG Toolkit for Java is a Java-based object engine that renders GLG objects in the Java environment. The Toolkit takes care of the low-level details of the rendering process, such as optimized damage repair, screen-resolution independent coordinate conversion, transparent zooming and panning, double-buffering and other coding-intensive driver-level tasks.

The Toolkit provides a high-level graphical object model which allows an application developer to concentrate on the logic of the application, speeding up the development process and dramatically increasing the developer's productivity.

The Toolkit contains the Graphics Builder, a graphical editor used to create graphical objects and define their attributes and dynamic properties without tedious programming. The resulting drawing is then saved into a file and loaded into a Java application using GLG's 100% pure Java class library.

Refer to the description of the com.genlogic package for more details as well as an overview of the GLG classes and their usage.

Global Configuration Resources

Global configuration resources may be used to control some aspects of the GLG Toolkit run-time behavior. Refer to the Appendix A: Global Configuration Resources chapter of the GLG Programming Reference Manual for a list of the global configuration resources.

Standard, Intermediate and Extended APIs.

The com.genlogic package contains Standard, Intermediate and Extended APIs, which provide programmatic access to GLG objects. Common GLG API methods are implemented for both the GLG bean and GlgObject classes. Some additional methods are implemented only for the GlgObject class.

• Standard API (Glg2.jar file) provides methods for loading the drawing created in the Graphics Builder, displaying and updating it with dynamic data, as well as handling user interaction (selecting objects with the mouse, pressing buttons, etc.)


• Extended API (GlgExt2.jar file) provides methods for creating objects programmatically, as well as methods for extended object manipulation (adding or deleting objects at run-time, dragging objects with the mouse, traversing the object hierarchy, querying a list of object resources, etc.), supplying the application program with all the functionality of the Graphics Builder at run-time.


• Intermediate API (GlgInt2.jar file) provides all functionality of the Extended API except the dynamic object creation.

GLG Graphics Server for JSP/JavaEE

Glg.Server.jar provides a GLG Graphics Server that is used to implement server-side JSP/JavaEE Web applications. This library has the same interface as the rest of the GLG API with a few additional GlgObject methods (SetImageSize, GetImageWidth and GetImageHeight) to be used in the JSP/JavaEE environment.

The GLG JavaScript Library may be used for client-side HTML5 & JavaScript Web applications used on web pages in a web browser.

Free Community Edition

GlgCE.jar file provides a free Community Edition of the GLG Java Class Library and includes all GLG APIs.

GlgServerCE.jar provides a free Community Edition of the GLG Graphics Server for JSP/JavaEE.
