Creating a Function to Tie the Application Together

There are three things that you can do with the application:

• Add new projects, using the wizard
• Maintain data about projects and tasks, using the second tab of the property sheet
• Maintain employee data, using the first tab of the property sheet

In this chapter, you create a simple function that calls the wizard and property sheet. You start with UIBASIC/UIBasicShell, which has a panel and a caption, but no associated processing.

Next, you modify the panel for your function by adding three buttons to it, which let users open the property sheet and the wizard:

You also specify a recognizable file name for the application, so that when you create an executable file (.EXE), its name makes sense.

To create a top-level interface:

1. Set the Model Editor object type to Function, and add the following triple:

   Project Manager is a UIBASIC/UIBasicShell
   

   UIBASIC/UIBasicShell is one of the simplest functions in the CA Plex Pattern Libraries. It has a panel with a caption, and a single event to close the panel. The action diagram has an Events Handler, where you specify how to respond to logical events you define on the panel, but not much processing beyond that.

   When you deploy your application, you want your executable file to have a meaningful name. The Project Manager function becomes the executable program. If you do not specify a file name for that function, CA Plex creates an executable with an automatically generated file name, such as AAc4F.exe.

2. Add the following triples:

   Project Manager file name Projects
   Project Manager impl name Projects
   

   Now, when you build your application, CA Plex gives it the name Projects.exe.
