NAME
viewres - graphical class browser for Xt
SYNOPSIS
viewres [-option ...]
DESCRIPTION
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
inherit from its parent) when a widget is created. This application
allows the user to visually examine the structure and inherited
resources for the Athena Widget Set.
OPTIONS
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
hierarchy to display. This is typically used to limit the
display to a subset of the tree. The default is Object.
-variable
This option indicates that the widget variable names (as
declared in header files) should be displayed in the nodes
rather than the widget class name. This is sometimes useful to
distinguish 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.
VIEW MENU
The way in which the tree is displayed may be changed through the
entries 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
operation 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
SetOrientation(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
SetOrientation(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.
SELECT MENU
Resources for a single widget class can be displayed by clicking
Button2 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
selected 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
operation may also be performed with the Select(nothing)
translation.
Select All
This entry adds all nodes to the selection list. This
operation 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
Select(ancestors) translation.
Select Children
This entry selects the immediate children of all selected
nodes. This operation may also be performed with the
Select(children) translation.
Select Descendants
This entry recursively selects all children of all selected
nodes. This operation may also be performed with the
Select(descendants) translation.
Select Has Resources
This entry selects all nodes that add new resources (regular or
constraint) to their corresponding widget classes. This
operation may also be performed with the Select(resources)
translation.
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
Select(shown) translation.
ACTIONS
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
following 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,
parent, 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.
