Summing up
That’s it! You have created your first Smalltalk application, STCalculatorApp. In doing so, you completed many of the most important tasks that you, as a Smalltalk programmer, will do repeatedly when creating applications.
• You now know how to use the Applications Browser to create an application.
• Within the Applications Browser, you can define new subclasses and extend existing classes.
• Using an Applications Browser, Classes Browser, or a Class Browser, you can add methods to a class in your application.
• You've seen how to browse through the class library, to see how a particular class works.
• And you know how to use the basic features of the Debugger to find errors.
One major step of the development cycle is missing: deploying an application and running it outside the development environment. This is more complicated a topic than can be covered with this first example. Please refer to Enhancing your applications > Packaging your VA Smalltalk application in the Visual Programming User Guide for information on how to build a run time image and launch it.
Now that you have build your first example, you can review the
software components and
tools you used to make it, or learn
concepts that allow you to control versions of the applications you develop alone or in a team.
