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 with
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 sec-
tion) 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 actu-
ally 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 vari-
ous 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 per-
formed with the Select(parent) translation.
Select Ancestors
This entry recursively selects all parents of all
selected nodes. This operation may also be per-
formed with the Select(ancestors) translation.
Select Children
This entry selects the immediate children of all
selected nodes. This operation may also be per-
formed with the Select(children) translation.
Select Descendants
This entry recursively selects all children of all
selected nodes. This operation may also be per-
formed 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 per-
formed 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) trans-
lation.
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.
