XmHierarchy(3) Library Functions Manual XmHierarchy(3) 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 Motif 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. New Resources +----------------------------------------------------------------------------------------------+ | | XmHierarchy Resource Set | | | | Name | Class | Type | Default | Access | +----------------------+----------------------+----------------+----------------------+--------+ | XmNautoClose | XmCAutoClose | Boolean | True | CSG | +----------------------+----------------------+----------------+----------------------+--------+ | XmNcloseFolderPixmap | XmCPixmap | Pixmap | XmUNSPECIFIED_PIXMAP | CSG | +----------------------+----------------------+----------------+----------------------+--------+ | XmNhorizontalMargin | XmCDimension | Dimension | 2 | CSG | +----------------------+----------------------+----------------+----------------------+--------+ | XmNnodeStateCallback | XmCNodeStateCallback | XtCallbackList | NULL | C | +----------------------+----------------------+----------------+----------------------+--------+ | XmNopenFolderPixmap | XmCPixmap | Pixmap | XmUNSPECIFIED_PIXMAP | CSG | +----------------------+----------------------+----------------+----------------------+--------+ | XmNrefigureMode | XmCBoolean | Boolean | True | CSG | +----------------------+----------------------+----------------+----------------------+--------+ | XmNverticalMargin | XmCDimension | Dimension | 2 | CSG | +----------------------+----------------------+----------------+----------------------+--------+ +----------------------+----------------------+----------------+----------------------+--------+ XmNautoClose This resource determines if the hierarchy should automatically restore a parent node's children when the parent node is re- opened. If autoClose is False, and the hierarchy is fully ex- panded 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 de- fault 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 sim- ply 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. +-----------------------------------------------------------------------------+ | | XmHierarchy Constraint Resource Set | | | | Name | Class | Type | Default | Access | +-----------------+-----------------+----------------------+---------+--------+ | XmNinsertBefore | XmCInsertbefore | Widget | NULL | CSG | +-----------------+-----------------+----------------------+---------+--------+ | XmNnodeState | XmCNodeState | XMHierarchyNodeState | XmOpen | CSG | +-----------------+-----------------+----------------------+---------+--------+ | XmNparentNode | XmCParentNode | Widget | NULL | CSG | +-----------------+-----------------+----------------------+---------+--------+ +-----------------+-----------------+----------------------+---------+--------+ XmNinsertBefore Specifies another node that has the same parentNode. This node will then be placed immediately before that node in the hierar- chy. 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", "al- waysOpen", and "hidden". XmNparentNode The hierarchy parent of this node. The parent node MUST be a wid- get 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, re- fer to the reference page for that superclass. +-----------------------------------------------------------------------------------------------------+

+-------------------------------+-------------------------------+----------------+----------------------+--------+ Callback Information When a folder is clicked, the routines registered on the XmNnodeStateCall- back 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. Set- ting openFolderPixmap or closeFolderPixmap is done through XtSetValues. IconButtons may only be manipulated by the Hierarchy.
