viewres - graphical class browser for Xt
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.
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.
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:
