NAME
MrmFetchWidget -- Fetches and creates an indexed (UIL named)
application widget and its children
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmFetchWidget(
MrmHierarchy hierarchy_id,
String index,
Widget parent_widget,
Widget *widget,
MrmType *class);
DESCRIPTION
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.
hierarchy_id 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.
parent_widget 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
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.
RETURN
This function returns one of the following status return constants:
MrmSUCCESS The function executed successfully.
MrmBAD_HIERARCHY The hierarchy ID was invalid.
MrmNOT_FOUND The widget was not found in UID hierarchy.
MrmFAILURE The function failed.
