X Version 11 (Release 6.1)
dynamic resource editor for X toolkit applications
Use editres to view the full widget hierarchy of any
X toolkit application that uses the editor's protocol. All
applications built with Motif on SCO Open Desktop 3.0 will be
able to communicate with the editres protocol.
You can also use editres to construct resource specifications,
apply the resource to the application, and view the results
dynamically. After you are satisfied with a resource
specification, editres will append the resource
string to your X resources file.
editres accepts all of the standard X Toolkit
command line options (see
The order of the command line options is not important.
editres provides a window consisting of the
following three areas:
A set of popup menus that gives access to all editres
Displays information about the action expected from the user.
Application Widget Tree
Area used to display the selected application's widget tree.
To begin an editres session, select the Get Widget Tree
menu item from the command menu. This changes the pointer cursor to crosshair.
Next, select the application you want to look at by clicking on
any of its windows. If this application understands the
editres protocol, then editres will display
the application's widget tree in its tree window. If
the application does not understand the protocol, that
fact appears in the message area after a few seconds.
Once you have a widget tree, you can select any of the other menu
options, as described in the next section.
Get Widget Tree
Allows the user to click on any application that uses the editres
protocol and receive its widget tree.
Refresh Current Widget Tree
editres only knows about the widgets that currently
exist. Many applications create and destroy widgets
on-the-fly, that is, within a single session. Selecting
this menu item will cause editres to ask the application to resend its
widget tree, thus updating its information to the new state of the application.
For example, xman only creates the widgets for its topbox when it
starts up. None of the widgets for the manual page window are created
until the user actually clicks on the Manual Page button. If
you retrieved the xman widget tree before the manual
page is active, you may want to refresh the widget tree after the manual
page has been displayed. This will also let you edit the manual page's
Dump Widget Tree to a File
When documenting applications it is often useful to be able to
dump the entire application widget tree to an ASCII file. This file
can then be included in the manual page. When this menu item is selected,
a popup dialog is activated. Type the name of the file in this
dialog, and either select Okay, or press <Enter>.
editres will now dump the widget tree to this file. To cancel the
file dialog, select the Cancel button.
Show Resource Box
This command pops up a resource box for the current application. This
resource box (described in detail below) will allow the user to see
exactly which resources can be set for the widget currently
selected in the widget tree display. Only one widget at a
time may be selected; otherwise, the resource box
will not pop up, and an error message will appear in the Message Area.
This command will pop up a simple dialog box for setting an arbitrary
resource on all selected widgets. You must type in the resource name,
as well as the value. You can use the <Tab> key to switch between the
resource name field and resource value field.
The Tree menu contains several commands that allow operations to
be performed on the widget tree:
Select Widget in Client
This menu item allows you to select any widget in the application.
editres will then highlight the corresponding element
on the widget tree display.
After you select this item, the pointer cursor again turns to a
crosshair. Click any pointer button on the widget you
wish to have displayed. Since some widgets are fully obscured by
their children, it is not possible to get to every widget this way.
However, this mechanism does give very useful feedback between the elements
in the widget tree and those in the actual application.
Select All; Unselect All; Invert All
These functions allow the user to select, unselect, or invert all
widgets in the widget tree.
Select Children; Select Parents
These functions select the immediate parent or children of each of the
currently selected widgets.
Select Descendants; Select Ancestors
These functions select all parents or children of each of the
currently selected widgets. This is a recursive search.
Show Widget Names; Show Class Names;
Show Widget IDs; Show Widget Windows
When the tree widget is initially displayed, the labels of each widget
in the tree correspond to the widget names. These functions will
cause the label of all widgets in the tree to be changed to show the
class name, IDs, or window associated with each widget in the application.
The widget IDs, and windows are shown as hex numbers.
In addition, there are keyboard accelerators for each of the
Tree operations. If the input focus is over an individual widget in
the tree, then that operation will only affect that widget. If the
input focus is in the Tree background, it will have
exactly the same effect as the corresponding menu item.
entries shown may be applied to any widget in the application. If
that widget is a child of the Tree widget, then it will only affect that
widget, otherwise it will have the same effect as the commands in the
Flash Active Widgets
This command is the inverse of the Select Widget in Client
command. It will show the user each widget that is currently selected in
the widget tree by flashing the corresponding widget in the
application numFlashes (three by default) times in the
Clicking button 1 on a widget acts as a toggle; for example,
depending on the current state (selected or unselected),
clicking button 1 on a widget could add that widget to a set of selected
Using the resource box
The resource box contains five different areas, discussed
here in the order in which they appear onscreen:
The resource line
This area at the top of the resource box shows the current resource
name exactly as it would appear if you were to save it to a file or
The widget names and classes
This area allows you to select exactly which widgets this resource will
apply to. The area contains four lines, the first contains the
name of the selected widget and all its ancestors, and the more restrictive
dot ``.'' separator. The second line contains the Class names
of each widget, and the less restrictive asterisk ``*'' separator.
The third line contains a set of special buttons called Any Widget
which will generalize this level to match any widget.
The last line contains a set of special buttons called Any
Widget Chain which will turn the single level into something that
matches zero or more levels.
The initial state of this area is the most restrictive, using the
resource names and the dot separator. By selecting the other buttons
in this area, you can ease the restrictions to allow more and more widgets
to match the specification. The extreme case is to select all the
Any Widget Chain buttons, which will match every widget in the
application. As you select different buttons, the tree display will update
to show you exactly which widgets will be affected by the current
Normal and constraint resources
The next area allows you to select the name of the normal or
constraint resources you wish to set. Some widgets may not have constraint
resources, so that area will not appear.
This next area allows you to enter the resource value. This value
should be entered exactly as you would type a line into your resource file.
Thus it should contain no unescaped new-lines.
There are a few
special character sequences for this file:
This will be replaced with a newline.
Where # is any octal digit. This will be replaced with a
single byte that contains this sequence interpreted as an octal number.
For example, a value containing a NULL byte can be stored by
This will compress to nothing.
This will compress to a single backslash.
This area contains the following command buttons:
Set Save File
This button allows the user to modify the file to which the resources
will be saved. This button will bring up a dialog box that will
ask you for a filename. After the filename has been entered, either
press <Enter> or click on the OK button. If you
do not want to change this file, click on the Cancel button.
This button will append the Resource line described above to the
end of the current save file. If no save file has been set, the
Set Save File dialog box will appear to prompt the user for a filename.
This button attempts to perform an XtSetValues call on all widgets
that match the Resource line described above. The value specified
is applied directly to all matching widgets.
Because this feature allows
users to put an application in states it may not be willing to handle,
a hook has been provided to allow specific applications to block these SetValues
requests (see the following section on blocking editres requests).
Due to design constraints imposed on the widgets by the X
Toolkit and the Resource Manager, trying to coerce an inherently
static system into dynamic behavior can cause strange results. The
results of an apply may not be the same as the results from
saving the value and restarting the application. This functionality
is provided to give you an approximate idea of what your
changes may accomplish, and the results obtained should be
consequently considered approximations.
Save and Apply
This button combines the Save and Apply actions described above into
Popdown Resource Box
This button will remove the resource box from the display.
Blocking editres requests
The editres protocol has been built into the Motif Widget set.
This gives all applications that are linked against Motif the
ability to speak to the resource editor. While this provides great
flexibility and is a useful tool, it can be abused. It is therefore possible
for any Motif application to specify a value for the editresBlock
resource described below, to keep editres from divulging information
about its internals, or to disable the SetValues part of the protocol.
editresBlock (Class: EditresBlock)
Specifies which type of blocking this application wishes to impose on the
The accepted values are:
Block all requests.
Block all setValues requests. This is the only editres
request that actually modifies the application. This is, in effect,
stating that the application is read-only.
Allow all editres requests.
Remember that these resources are set on any Xaw application, not
editres. They allow individual applications to keep all or some
of the requests editres makes from succeeding. Because
editres is also an Xaw application, it may also be viewed and modified
by editres (in a recursive manner). These commands can be blocked
by setting the editresBlock resource on editres itself.
/usr/lib/X11/app-defaults/Editres specifies required resources.
For editres, the available application resources are:
numFlashes (Class: NumFlashes)
Specifies the number of times the widgets in the application
will be flashed when the Show Active Widgets command is invoked.
flashTime (Class: FlashTime)
Amount of time between the flashes described above.
flashColor (Class: flashColor)
Specifies the color used to flash application widgets. A bright color
should be used that will immediately draw your attention to the area being
flashed, such as red or yellow.
saveResourcesFile (Class: SaveResourcesFile)
This is the file the resource line will be appended to when the
Save button is activated in the resource box.
In order to specify resources, it is useful to know the hierarchy of
the widgets which compose editres. In the notation below,
indentation indicates hierarchical structure. The widget class name
is given first, followed by the widget instance name.
to get the default host and display number.
to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
