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.
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.
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.
Resources may be specified for the following widgets:
