ClassViewer - $99.00

ClassViewer is a utility program that combines the features of the Clarion Application Builder Class Viewer and the CallTree utility. With this program you can analyze all classes (not just ABC), make annotations, view the class source and help files.

We develop a lot of classes here at Devuna. It is not possible to use Clarion's Application Builder Class Viewer while actually working in the Clarion editor. I found it very time consuming to exit my editing, go to the globals tab, scroll the tabs and access the Application Builder Class Viewer. Not only that, I often forgot the details by the time I returned to my editing.

Another shortcoming of the Application Builder Class Viewer is that it only works with Clarion's ABC classes or classes developed by others that contain the '!ABCIncludeFile' comment in the include (.INC) file. Developers often add this comment just so their classes can be viewed with the Application Builder Class Viewer. The down side of creating a class with the !ABCIncludeFile comment is that the application generator creates an instance of the object in your global DLL or executable, even if you don't want it. Also, some user developed classes require supporting libraries to be linked in for the classes to compile properly and the default generator behaviour can cause compile errors.

I was constantly writing notes to keep track of what various class methods did and how they behaved and interacted. The documentation and help files really could use an annotation mechanism.

There is also a Clarion utility named calltree.exe that lets you view the class method calling hierarchy. I used it a few times but discovered that it wasn't always accurate.

Clearly, a utility program that let me view any class, it's methods and interfaces, it's call tree, structures, equate values, and source code was something that I could use.

Our ClassViewer application does all this and more. It works with classes from all versions of Clarion and allows the user to keep notes about the methods. It gives you the ability to view all classes or just the ABC classes and access the help file. The user can also specify other files to include in the scan process as well as set color and tooltip preferences.

If you are a serious developer and write your own Clarion classes, this utility is must have.

Devuna highly recommends the book, "Programming Objects in Clarion", from RADFusion as a nice companion to ClassViewer.
