For the sake of brevity and clarity, many of the features of forms and controls are not implemented in the sample application. For example, we modified only two of the many menu items in the ABL MDI Form.
The intention of the sample application is not to implement every feature. Rather, the intention is to give you an idea of what you can do in the Visual Designer by showing you a representative sample of the forms and controls. You should know how to:
Use the tools of the Visual Designer to add, arrange, and format various user interface elements
Use properties and events to modify the behavior of forms and controls
Implement data binding
The next step is to do some experimenting on your own. You can use this sample application as your starting point.
