viewres [-option ...]
The viewres program displays a tree showing the widget class hierarchy of the Athena Widget Set. Each node in the tree can be expanded to show the resources that the corresponding class adds (i.e. does not in‐ herit from its parent) when a widget is created. This application al‐ lows the user to visually examine the structure and inherited resources for the Athena Widget Set.
Viewres accepts all of the standard toolkit command line options as well as the following: -top name This option specifies the name of the highest widget in the hi‐ erarchy to display. This is typically used to limit the dis‐ play to a subset of the tree. The default is Object. -variable This option indicates that the widget variable names (as de‐ clared in header files) should be displayed in the nodes rather than the widget class name. This is sometimes useful to dis‐ tinguish widget classes that share the same name (such as Text). -vertical This option indicates that the tree should be displayed top to bottom rather left to right.
The way in which the tree is displayed may be changed through the en‐ tries in the View menu: Show Variable Names This entry causes the node labels to be set to the variable names used to declare the corresponding widget class. This op‐ eration may also be performed with the SetLabelType(variable) translation. Show Class Names This entry causes the node labels to be set to the class names used when specifying resources. This operation may also be performed with the SetLabelType(class) translation. Layout Horizontal This entry causes the tree to be laid out from left to right. This operation may also be performed with the SetOrienta‐ tion(West) translation. Layout Vertical This entry causes the tree to be laid out from top to bottom. This operation may also be performed with the SetOrienta‐ tion(North) translation. Show Resource Boxes This entry expands the selected nodes (see next section) to show the new widget and constraint resources. This operation may also be performed with the Resources(on) translation. Hide Resource Boxes This entry removes the resource displays from the selected nodes (usually to conserve space). This operation may also be performed with the Resources(off) translation.
Resources for a single widget class can be displayed by clicking But‐ ton2 on the corresponding node, or by adding the node to the selection list with Button1 and using the Show Resource Boxes entry in the View menu. Since Button1 actually toggles the selection state of a node, clicking on a selected node will cause it to be removed from the se‐ lected list. Collections of nodes may also be selected through the various entries in the Select menu: Unselect All This entry removes all nodes from the selection list. This op‐ eration may also be performed with the Select(nothing) transla‐ tion. Select All This entry adds all nodes to the selection list. This opera‐ tion may also be performed with the Select(all) translation. Invert All This entry adds unselected nodes to, and removes selected nodes from, the selection list. This operation may also be performed with the Select(invert) translation. Select Parent This entry selects the immediate parents of all selected nodes. This operation may also be performed with the Select(parent) translation. Select Ancestors This entry recursively selects all parents of all selected nodes. This operation may also be performed with the Se‐ lect(ancestors) translation. Select Children This entry selects the immediate children of all selected nodes. This operation may also be performed with the Se‐ lect(children) translation. Select Descendants This entry recursively selects all children of all selected nodes. This operation may also be performed with the Se‐ lect(descendants) translation. Select Has Resources This entry selects all nodes that add new resources (regular or constraint) to their corresponding widget classes. This opera‐ tion may also be performed with the Select(resources) transla‐ tion. Select Shown Resource Boxes This entry selects all nodes whose resource boxes are currently expanded (usually so that they can be closed with Hide Resource Boxes). This operation may also be performed with the Se‐ lect(shown) translation.
The following application actions are provided: Quit() This action causes viewres to exit. SetLabelType(type) This action sets the node labels to display the widget variable or class names, according to the argument type. SetOrientation(direction) This action sets the root of the tree to be one of the follow‐ ing areas of the window: West, North, East, or South. Select(what) This action selects the indicated nodes, as described in the VIEW MENU section: nothing (unselects all nodes), invert, par‐ ent, ancestors, children, descendants, resources, shown. Resources(op) This action turns on, off, or toggles the resource boxes for the selected nodes. If invoked from within one of the nodes (through the keyboard or pointer), only that node is used.
