NAME

MrmFetchWidget --- Fetches and creates an indexed (UIL named) application widget and its children  

SYNOPSIS

#include <Mrm/MrmPublic.h>
Cardinal MrmFetchWidget(
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.

All widgets fetched by a call to MrmFetchWidget are not managed at the time of their creation callbacks.

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.
widget
Returns the widget ID of the created widget.
class
This argument must be set to an actual pointer; it cannot be a NULL pointer. MrmFetchWidget sets this argument to an implementation dependent value.

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 template 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

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.
