MrmFetchWidget(3X)MrmFetchWidget(3X)NAMEMrmFetchWidget - Fetches and creates any indexed (UIL named) applica‐
tion widgets and its children
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmFetchWidget(hierarchy_id, index, parent_widget, widget,
class)
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. Specifies the ID of the
uid hierarchy that contains the interface definition. The hierarchy_id
was returned in a previous call to MrmOpenHierarchyPerDisplay. Speci‐
fies the UIL name of the widget to fetch. Specifies the parent widget
ID. Returns the widget ID of the created widget. Returns the class
code identifying MRM's widget class. The widget class code for the main
window widget, for example, is MRMwcMainWindow. Literals identifying
MRM widget class codes are defined in <Mrm.h>.
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 refer‐
enced (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 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 VALUE
This function returns one of these status return constants: The func‐
tion executed successfully. The hierarchy ID was invalid. The widget
was not found in UID hierarchy. The function failed.
