Using dBASE Plus design tools, you can create the visual elements of an application quickly, in a manner that promotes reuse of design elements rather than repeated reinvention.  Using the Component palette, you simply drag and drop both the visible user-interface components (also known as controls or objects) and the invisible data objects onto forms.  The Inspector gives you an easy way to set an object’s attributes, or properties, and access its event handlers and methods directly, without hunting.
