Widget Attributes

Every widget or handle has certain attributes. Each attribute stores a value associated with the widget or handle. This value represents an aspect, state, or capability of the widget. For example, most widgets have a VISIBLE attribute that is either TRUE or FALSE (that is, the widget is either visible or invisible).

Widget attributes fall into several basic categories:

Each type of widget has its own attributes. For example, the attributes supported for a button are different than those supported for a frame. For a list of the attributes supported by each widget, see the reference entry for the widget in the Progress Language Reference .

Handle attributes correspond to the type of object the handle references:

Some attributes are set when the widget or object is created and are inaccessible to the Progress programmer. Other attributes can be read and, in some cases, updated within the application. For example, you can enable or disable input on a menu item by changing the value of its SENSITIVE attribute.
