Every component has
a
defaultAttribute attribute that is
inherited from the Object class. A component's
defaultAttribute is set to the attribute whose value is most often needed from that
component. For example, the
defaultAttribute attribute for a combo box control is
selectedItem, which is the item that is selected from the list that the combo
box displays.
The
defaultAttribute attribute also affects some behaviors of the Class Editor and the
Properties window. Actions that prompt for an attribute
are initially set to the value of a component's
defaultAttribute. For example, when you specify an attribute link, the value of Link
to defaults to the value of the source component's
defaultAttribute attribute. The dragInfo and dropInfo
values that pass information between objects during drag and drop
processes also use the value of the
defaultAttribute attribute.
Many SAS classes, including
most visual components, have values specified for
defaultAttribute.
To specify or change
the value of the
defaultAttribute attribute
for a particular class using the Class Editor:
-
Select the
Attributes node, and then select the
defaultAttribute attribute.
-
Right-click and select
Override from the pop-up menu.
-
In the Initial Value
field, select an attribute from the drop-down list. Note that the
list contains only attributes that are currently defined on the class.
-
You can also specify
the value of
defaultAttribute at build
time using the
Properties window. Valid selections
are limited to the attributes that are currently defined for the instance
of the class.
