MrmFetchWidgetOverride(library call)

NAME
MrmFetchWidgetOverride — Fetches any indexed (UIL named) application widget. It overrides the arguments specified for this application widget in UIL

SYNOPSIS

#include <Mrm/MrmPublic.h>
Cardinal MrmFetchWidgetOverride(
MrmHierarchy hierarchy_id,
String index,
Widget parent_widget,
String override_name,
ArgList override_args,
Cardinal override_num_args,
Widget *widget,
MrmType *class);

DESCRIPTION

The MrmFetchWidgetOverride function is the extended version of MrmFetchWidget. It is identical to MrmFetchWidget, except that it allows the caller to override the widget's name and any arguments that MrmFetchWidget would otherwise retrieve from the UID file or one of the defaulting mechanisms. That is, the override argument list is not limited to those arguments in the UID file.

The override arguments apply only to the widget fetched and returned by this function. Its children (subtree) do not receive any override parameters.

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.

override_name
    Specifies the name to override the widget name. Use a NULL value if you do not want to override the widget name.

override_args
    Specifies the override argument list, exactly as given to XtCreateWidget (conversion complete and so forth). Use a NULL value if you do not want to override the argument list.

override_num_args
    Specifies the number of arguments in override_args.

widget
    Returns the widget ID of the created widget.

class
    Returns the class code identifying MRM's widget class. Literals identifying MRM widget class codes are defined in the include file Mrm/MrmPublic.h.

RETURN VALUE

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.
