This section describes the components of the techexplorer add-in Software Development Kit (SDK). This section describes the directory structure of the add-in SDK. The sample and template source code bundles distributed with the techexplorer add-in SDK provide the pieces necessary for add-in development.
The techexplorer add-in API is only available on Windows 98/95/NT and Macintosh. The Examples provided are distributed in the techexplorer add-in SDK and can be compiled for Windows and the Macintosh using Microsoft Visual C++ 6.0 and CodeWarrior Pro 5.
The add-in SDK C++ source code is located in the AddInsSDK subdirectory of the techexplorer distribution. The following is an annotated listing of the structure of the techexplorer add-in SDK directory hierarchy.
| Directory | Description |
| AddInsSDK |
Within this directory reside two subdirectories and two files used by techexplorer
add-ins. These files include the TaApi.h header file and
TaApi.cpp source
file. Both of these files provide the definitions and implementations necessary for
interfacing C/C++ code with techexplorer. They are not intended to be
modified by add-in developers.
|
| AddInsSDK/DOM | Interface code for accessing the document object model via a C++ add-in. |
| AddInsSDK/DocumentExplorer | The DocumentExplorer add-in displays the document hierarchy in the form of a tree as well as provides a graphical interface for Document Object Model operations. |
| AddInsSDK/Simple | The Simple add-in can display either a provided text string or the contents of a URL in a popup window. |
| AddInsSDK/Random |
The Random add-in produces a random integer and serves as an example of an add-in
the makes use of the AddInBlockingEvaluate function.
|
| AddInsSDK/Template | The templates provided are empty add-ins that can be used as the starting point for developing techexplorer add-ins. |
The DocumentExplorer add-in displays the document
hierarchy in the form of a tree as well as provides a graphical interface for Document Object
Model operations. The add-in registers as handling the application/x-document-explorer-string
MIME type. The DocumentExplorer is a good example of building a techexplorer add-in that makes
use of the Document Object Model (DOM) API.
application/x-simple-url and application/x-simple-string
MIME types. It is intended to show how to use the basic add-in API (initialize,
shutdown, instance create, instance delete), asynchronous document operations (request/fetch URLs),
as well as the Evaluation API (evaluate, enable/disable evaluate).
The Random add-in implements the AddInBlockingEvaluate method by producing
a random integer seeded by using the current time. The add-in registers as handling the
application/x-random MIME type.
