MrmFetchWidget(library call) MrmFetchWidget(library call) 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 wid- get 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 previ- ous 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 implementa- tion 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 ref- erenced (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. RELATED

DwtFetchWidget(3Dwt) DwtFetchWidget(3Dwt) Name DwtFetchWidget - Fetches and then creates any indexed (UIL named) application widget and its children. Syntax #include <X11/DwtAppl.h> Cardinal DwtFetchWidget(hierarchy_id, index, parent_widget, widget_return, class_return) DRMHierarchy hierarchy_id; String index; Widget parent_widget; Widget *widget_return; DRMType *class_return; Arguments hierarchy_id Specifies the ID of the UID hierarchy that contains the interface definition. The hierarchy_id was returned in a previous call to DwtOpenHierarchy. index Specifies the UIL name of the widget to fetch. parent_widget Specifies the parent widget ID. widget_return Returns the widget ID of the created widget. If this is not NULL when you call DwtFetchWidgetOverride, DRM assumes that the wid- get has already been created and DwtFetchWidgetOverride returns DRMFailure. class_return Returns the class code identifying DRM's widget class. The widget class code for the main window widget, for example, is DRMwc- MainWindow. Literals identifying DRM widget class codes are defined in DRM.h. Description The DwtFetchWidget function fetches and then creates an indexed application widget and its children. The indexed application widget is any widget that is named in UIL and that is not the child of any other widget in the UID hierarchy. 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. DwtFetchWidget does not execute XtManageChild for the newly created widget. DwtFetchWidget fetches widgets where DwtFetchInterfaceModule is not used. DwtFetchWidget provides specific control over which widgets are fetched from a UIL file; DwtFetchInterfaceModule, on the other hand, fetches all widgets in a single call. An application can fetch any named widget in the UID hierarchy using DwtFetchWidget. DwtFetchWidget can be called at any time to fetch a widget that was not fetched at application startup. DwtFetchWidget determines if a widget has already been fetched by checking widget_return for a NULL value. Non-NULL values signify that the widget already has been fetched, and DwtFetchWidget fails. DwtFetchWidget 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. DwtFetchWidget 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. Return Values This function returns one of these status return constants: DRMSuccess The function executed successfully. DRMNotFound Widget not found in UID hierarchy. DRMFailure The function failed.
