Scripting the techexplorer Hypermedia Browser

This section is of a technical nature and is for readers who are familiar with C++, Java, and JavaScript programming. You may wish to skip this section if you are solely interested in viewing and creating techexplorer documents.

The term scripting means to control the actions of one software application from another application. In the web browser context, this refers to the interaction of plug-ins, ActiveX controls, JavaScript programs, Java applets, and other software programs.

Note that beginning with Version 3.5 of techexplorer the scripting interfaces are now provided by a top-level 'integre' package. This change will require source code modifications in package name references in any Java/JavaScript code that imports the older versions of these packages.

The techexplorer Java scripting interface serves as the "glue" for developing interactive scientific and technical documents. By using techexplorer, such documents are able to leverage Internet programming languages, as well as specialized applications from the large collection of scientific processors and renderers.

In the sections that follow, we discuss how you can control techexplorer from Java applets, JavaScript programs and C++ programs.

Note: These examples illustrate using techexplorer in Internet Explorer and in Netscape version 4. When using Internet Explorer, you may need to disable the Sun Java Plugin to view some of these examples. See the Compatibility section for details.

Begin with an overview of the basic HTML Elements and concepts needed for cross web browser scripting development using techexplorer.
Get started quickly by writing a JavaScript LaTeX editor that makes use of web browser objects, HTML forms and the techexplorerPlugin class.
Build on the JavaScript LaTeX editor to assemble a JavaScript LaTeX/MathML editor and translator
Use JavaScript to automatically size the width and height of embedded windows. You can use this technique to ensure that inline techexplorer equations embedded in HTML remain "scroll bar free!"
Configure and use your Java development environment to create, compile and run a Java applet version of the LaTeX editor.
Create the The GraphIT application, a techexplorer enhanced course module for understanding equations. This example makes use of inter-applet communication and techexplorer-to-Java connectivity.
Explore the JavaScript communication layer example for an alternative method that can be used to deploy applications involving Java applets, JavaScript, and techexplorer. This example retains compatibility with the Sun Java Plugin.
Explore the Event Monitor applet that provides a dynamic textual representation of events triggered by techexplorer instances, as well as a mechanism for toggling such events. This example expands on the concepts covered through the development of the GraphIT application.
Learn how to use Java threads to create a MathAnimation.
Learn about the techexplorer implementation of the W3C Document Object Model application programming interface. Java applications and C++ add-ins can now programatically manipulate the techexplorer document tree!

Put together a Spring Mass course module that uses the Document Object Model API to connect a spring mass simulation Java applet to a techexplorer document.
Look "under the hood" of the Expression Selector and learn how to program a Java application that uses techexplorer events and the Document Object Model.

Use the techexplorer Add-in conduit application to bridge Java and external C/C++ applications.
Jump start your techexplorer Java development by making use of the Example/API link matrix.
Browse the annotated techexplorer Core Java API Specification.
