"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" "MrmFAILURE"

This function returns one of the following status return constants:

MrmSUCCESS

The function executed successfully.

MrmBAD_HIERARCHY

The hierarchy ID was invalid.

MrmNOT_FOUND
