NAME

XmHierarchy --- The Hierarchy widget class  

SYNOPSIS

#include <Xm/Hierarchy.h>
 

DESCRIPTION

The Hierarchy widget is not intended to be instantiated itself, but rather should be used as the base class for any widget that would like to present a hierarchy of information to the user that is different for the actual widget instance hierarchy of the application. This base class is currently used for two widgets in the OpenMotif widget set, Tree and Outline, giving those two widgets a very similar API.

Note: The Hierarchy widget assumes that it will be totally responsible for mapping and unmapping its children. Therefore no child of this widget should ever modify its mappedWhenManaged resource. If a child does modify this resource the behavior is undefined.  

Classes

Hierarchy inherits behaviour, resources, and traits from Core, Composite, Composite, Constraint, and XmManager classes.

The class pointer is xmHierarchyWidgetClass.

The class name is XmHierarchy.

XmNautoClose
This resource determines if the hierarchy should automatically restore a parent node's children when the parent node is reopened. If autoClose is False, and the hierarchy is fully expanded when the root node is closed, then the entire hierarchy will be displayed as expanded when the root node is reopened. If autoClose is True, then the root node's children are closed when the root node is reopened.
XmNcloseFolderPixmap
This resource defines a pixmap for the closed representation of the folder pixmap to be used throughout the tree. It can be a color pixmap or bitmap. If the user does not specify a pixmap the default bitmap will be used.
XmNhorizontalMargin
XmNverticalMargin
The exact definition of these resources are left to the subclass of the hierarchy widget that does the geometry layout. They are intended to be used as the amount of space between the object and the edges of the window it is displayed in. They are included here for consistency.
XmNopenFolderPixmap
This resource defines a pixmap for the open representation of the folder pixmap to be used throughout the tree . It can be a color pixmap or bitmap. If the user does not specify a pixmap the default opened folder bitmap.
XmNnodeStateCallback
The list of callback routines called when a folder button is clicked. See "Callback Routine" for more details.
XmNrefigureMode
This resource determines whether the Hierarchy should adjust the sizes of the children after a geometry or resize request, or simply ignore the request. This resource is very useful in improving the performance of an application that is making a large number of geometry changes all at once.

XmNparentNodeXmCParentNodeWidgetNULLCSG





XmNinsertBefore
Specifies another node that has the same parentNode. This node will then be placed immediately before that node in the hierarchy. If this value is NULL then the node will be inserted at the end of the list. This resource allows the hierarchy's children to be reordered.
XmNnodeState
The state of this node. Acceptable values are: XmOpen, XmClosed, XmAlwaysOpen, and XmHidden. A type converter has been registered that can convert the following strings: "open", "close", "alwaysOpen", and "hidden".
XmNparentNode
The hierarchy parent of this node. The parent node MUST be a widget sibling of the current node.
 

Inherited Resources

Hierarchy inherits behavior and resources from the superclasses described in the following tables. For a complete description of each resource, refer to the reference page for that superclass.

Callback Information

When a folder is clicked, the routines registered on the XmNnodeStateCallback list are passed a pointer to the following structure as client data:

typedef struct _XmHierarchyNodeStateData {
        Widget widget;
        XmHierarchyNodeState state;
} XmHierarchyNodeStateData;
widget
the child node of Hierarchy being opened or closed.
state
the current XmNnodeState (after the click) of the node. Legal values are XmOpen, XmClosed, XmAlwaysOpen, and XmHidden.
 

Children

The hierarchy maintains IconButtons for each node in the hierarchy. Setting openFolderPixmap or closeFolderPixmap is done through XtSetValues. IconButtons may only be manipulated by the Hierarchy.
