6.8.2 Components

Visual LANSA has the following types of components:

  • Fields. Any LANSA field you use in an application becomes a component.
  • Forms. A form corresponds to a window of an application.
  • Controls. These are the graphical widgets put on the form. Examples of controls are command buttons, list boxes, videos, labels, tree views, radio buttons and track bars.
  • Reusable parts. These parts contain controls and code which can be reused in forms (or other reusable parts).
  • Visual Styles. This is a special kind of component which controls the appearance of individual fields, forms and controls or entire applications.
  • Bitmaps and icons. These are images which are shared by many applications.
  • ActiveX controls. These are third-party standard reusable components.
  • WAMs. These components use XML to deliver technology services for a variety of client computing devices, including browsers.
