MrmFetchWidget — Fetches and creates an indexed (UIL named) application
widget and its children
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
execute XtManageChild 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.
index Specifies the UIL name of the widget to fetch.
Specifies the parent widget ID.
widget Returns the widget ID of the created widget.
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. MrmFetchWidget can be called at any time to fetch a
widget that was not fetched at application 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
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
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.
