MrmFetchWidget -- Fetches and creates an indexed (UIL named) application widget and its
The MrmFetchWidget function fetches and creates an indexed application widget and its
children. The indexed application widget is any widget that is named in UIL. In fetch
operations, the fetched widget's subtree is also fetched and created. This widget must
not appear as the child of a widget within its own subtree. MrmFetchWidget does not exe-
cute XtManageChild for the newly created widget.
All widgets fetched by a call to MrmFetchWidget are not managed at the time of their cre-

class This argument must be set to an actual pointer; it cannot be a NULL pointer.
MrmFetchWidget sets this argument to an implementation dependent value.
An application can fetch any named widget in the UID hierarchy using MrmFetchWidget. Mrm-
FetchWidget can be called at any time to fetch a widget that was not fetched at applica-
tion startup. MrmFetchWidget can be used to defer fetching pop-up widgets until they are
first referenced (presumably in a callback), and then used to fetch them once.
MrmFetchWidget can also create multiple instances of a widget (and its subtree). In this
case, the UID definition functions as a template; a widget definition can be fetched any
number of times. An application can use this template to make multiple instances of a
widget, for example, in a dialog box box or menu.
The index (UIL name) that identifies the widget must be known to the application.
This function returns one of the following status return constants:
The function executed successfully.
The hierarchy ID was invalid.
The widget was not found in UID hierarchy.
The function failed.
