XView Attributes
This section lists all XView attributes in alphabetical order. Each attribute’s description is in
the format shown by the entry on this page. Only the fields appropriate to the particular attri-
bute are shown.

Return Type: The return type describes the type that the attribute should return on a call to xv_get().
Note that this return type is normally coerced by the programmer. This field is only
shown when the attribute is valid with xv_get().
Argument: This shows the first programmer supplied value associated with the attribute. If an attri-
bute has multiple values, then the type of each value is shown in multiple Argument
fields.
Valid Values: Shows a list {in brackets} of values that are valid for the attribute.
Default: The default field shows the default value for the attribute.
Procs: Shows the attribute’s valid procedures. In this field, xv_create, xv_find, xv_get,

Objects: The objects field shows the valid object or objects for the attribute. Attributes are divided
into three classes: generic, common, and specific. (For more information, refer to the
