— Fetches and creates an indexed (UIL named)
application widget and its children
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 execute
for the newly created widget.
All widgets fetched by a call to MrmFetchWidget
are not managed at the
time of their creation callbacks.
- Specifies the ID of the UID hierarchy that contains the interface
definition. The value of hierarchy_id was returned in a previous
call to MrmOpenHierarchyPerDisplay.
- Specifies the UIL name of the widget to fetch.
- Specifies the parent widget ID.
- Returns the widget ID of the created widget.
- This argument must be set to an actual pointer; it cannot be a NULL
pointer. MrmFetchWidget sets this argument to an implementation

can be used to defer fetching pop-up widgets until they
are first referenced (presumably in a callback), and then used to fetch them
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
This function returns one of the following status return constants:
- The function executed successfully.

- The widget was not found in UID hierarchy.
- The function failed.
