Cardinal MrmFetchWidgetOverride(

MrmType *class);
"MRM function" "MrmFetchWidgetOverride"
"MrmFetchWidgetOverride" "definition"
DESCRIPTION¶
The
MrmFetchWidgetOverride function "MrmFetchWidgetOverride"
"description" 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¶
"MrmSUCCESS" "MrmBAD_HIERARCHY" "MrmNOT_FOUND"

- The function executed successfully.
- MrmBAD_HIERARCHY
