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.
| hierarchy_id | Specifies the ID of the UID hierarchy that contains the interface definition. The 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 | 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 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 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.
This function returns one of these 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. |
