editres - a dynamic resource editor for X Toolkit
applications

_E_d_i_t_r_e_s accepts all of the standard X Toolkit command line
options (see _X(_1)). The order of the command line options
is not important.
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
Editres is a tool that allows users and application
developers to view the full widget hierarchy of any X
Toolkit application that speaks the Editres protocol. In
addition, editres will help the user construct resource
specifications, allow the user to apply the resource to the
application and view the results dynamically. Once the user
is happy with a resource specification editres will append
the resource string to the user's X Resources file.
UUUUSSSSIIIINNNNGGGG EEEEDDDDIIIITTTTRRRREEEESSSS
_E_d_i_t_r_e_s provides a window consisting of the following four
areas:
Menu Bar A set of popup menus that allow you
full access to editres's features.
Panner The panner allows a more intuitive
way to scroll the application tree
display.
Message Area Displays information to the user
about the action that editres
expects of her.
Application Widget Tree This area will be used to display
the selected application's widget
tree.
To begin an editres session select the GGGGeeeetttt WWWWiiiiddddggggeeeetttt TTTTrrrreeeeeeee menu
item from the command menu. This will change the pointer
cursor to cross hair. You should now select the application
you wish 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 editres
protocol editres will inform you of this fact in the message
area after a few seconds delay.
Once you have a widget tree you may now select any of the

other menu options. The effect of each of these is described
below.
CCCCOOOOMMMMMMMMAAAANNNNDDDDSSSS
Get Widget Tree
Allows the user to click on any application that
speaks the editres protocol and receive its widget
tree.
Refresh Current Widget Tree
Editres only knows about the widgets that exist at
the present time. Many applications create and
destroy widgets on the fly. 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
_t_o_p_b_o_x when it starts up. None of the widgets for
the manual page window are created until the user
actually clicks on the _M_a_n_u_a_l _P_a_g_e button. If you
retrieved xman's widget tree before the the manual
page is active, you may wish to refresh the widget
tree after the manual page has been displayed. This
will allow you to also edit the manual page's
resources.
Dump Widget Tree to a File
For 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 _o_k_a_y, or type
a carriage-return. Editres will now dump the widget
tree to this file. To cancel the file dialog,
select the _c_a_n_c_e_l button.
Show Resource Box
This command will popup 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 that is
currently selected in the widget tree display. Only
one widget may be currently selected; if greater or
fewer are selected editres will refuse to pop up the
resource box and put an error message in the MMMMeeeessssssssaaaaggggeeee
AAAArrrreeeeaaaa.
Set Resource
This command will popup 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 the resource
value field.
Quit Exits editres.
TTTTRRRREEEEEEEE CCCCOOOOMMMMMMMMAAAANNNNDDDDSSSS
The TTTTrrrreeeeeeee 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 the widget tree display. Once
this menu item is selected the pointer cursor will
again turn to a crosshair, and you must click any
pointer button in 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, but 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 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 aaaallllllll
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 effect
that widget. If the input focus is in the Tree background
it will have exactly the same effect as the corresponding
menu item.
The translation 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 tree menu.
Flash Active Widgets
This command is the inverse of the SSSSeeeelllleeeecccctttt WWWWiiiiddddggggeeeetttt iiiinnnn
CCCClllliiiieeeennnntttt command, it will show the user each widget that
is currently selected in the widget tree, by flashing
the corresponding widget in the application _n_u_m_F_l_a_s_h_e_s
(three by default) times in the _f_l_a_s_h_C_o_l_o_r.

Clicking button 1 on a widget adds it to the set of
selected widgets. Clicking button 2 on a widget
deselects all other widgets and then selects just that
widget. Clicking button 3 on a widget toggles its
label between the widget's instance name the widget's
class name.

The resource box contains five different areas. Each of the
areas, as they appear on the screen, from top to bottom will
be discussed.
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 apply it.
Page 4 (printed 4/30/98)
EEEEDDDDIIIITTTTRRRREEEESSSS((((1111)))) XXXX VVVVeeeerrrrssssiiiioooonnnn 11111111 ((((RRRReeeelllleeeeaaaasssseeee 6666....3333)))) EEEEDDDDIIIITTTTRRRREEEESSSS((((1111))))
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 less
specific the Class names of each widget, and well as
the less restrictive star (****) separator. The third
line contains a set of special buttons called AAAAnnnnyyyy
WWWWiiiiddddggggeeeetttt which will generalize this level to match any
widget. The last line contains a set of special
buttons called AAAAnnnnyyyy WWWWiiiiddddggggeeeetttt CCCChhhhaaaaiiiinnnn 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 AAAAnnnnyyyy WWWWiiiiddddggggeeeetttt CCCChhhhaaaaiiiinnnn 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 effected by the
current resource specification.
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.
Resource Value
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:
\n - 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 specifying
\000.
\<new-line> - This will compress to nothing.
\\ - This will compress to a single backslash.

This area contains several command buttons, described
in this section.
Set Save File
This button allows the user to modify file that the
resources will be saved to. This button will bring up
a dialog box that will ask you for a filename; once the
filename has been entered, either hit carriage-return
or click on the _o_k_a_y button. To pop down the dialog
box without changing the save file, click the _c_a_n_c_e_l
button.
Save This button will append the rrrreeeessssoooouuuurrrrcccceeee lllliiiinnnneeee described
above to the end of the current save file. If no save
file has been set the SSSSeeeetttt SSSSaaaavvvveeee FFFFiiiilllleeee dialog box will be
popped up to prompt the user for a filename.
Apply
This button attempts to perform a XtSetValues call on
all widgets that match the rrrreeeessssoooouuuurrrrcccceeee lllliiiinnnneeee described
above. The value specified is applied directly to all
matching widgets. This behavior is an attempt to give
a dynamic feel to the resource editor. Since 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 BBBBlllloooocccckkkkiiiinnnngggg EEEEddddiiiittttrrrreeeessss RRRReeeeqqqquuuueeeessssttttssss below).
Unfortunately 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. There is
no guarantee that the results of an apply will be the
same as what will happen when you save the value and
restart the application. This functionality is
provided to try to give you a rough feel for what your
changes will accomplish, and the results obtained
should be considered suspect at best. Having said
that, this is one of the neatest features of editres,
and I strongly suggest that you play with it, and see
what it can do.
Save and Apply
This button combines the Save and Apply actions
described above into one button.
Popdown Resource Box
This button will remove the resource box from the
display.
BBBBLLLLOOOOCCCCKKKKIIIINNNNGGGG EEEEDDDDIIIITTTTRRRREEEESSSS RRRREEEEQQQQUUUUEEEESSSSTTTTSSSS
The editres protocol has been built into the Athena Widget
Page 6 (printed 4/30/98)
EEEEDDDDIIIITTTTRRRREEEESSSS((((1111)))) XXXX VVVVeeeerrrrssssiiiioooonnnn 11111111 ((((RRRReeeelllleeeeaaaasssseeee 6666....3333)))) EEEEDDDDIIIITTTTRRRREEEESSSS((((1111))))
set. This allows all applications that are linked against
Xaw to be able to speak to the resource editor. While this
provides great flexibility, and is a useful tool, it can
quite easily be abused. It is therefore possible for any
Xaw application to specify a value for the eeeeddddiiiittttrrrreeeessssBBBBlllloooocccckkkk
resource described below, to keep editres from divulging
information about its internals, or to disable the SSSSeeeettttVVVVaaaalllluuuueeeessss
part of the protocol.
eeeeddddiiiittttrrrreeeessssBBBBlllloooocccckkkk ((((Class EEEEddddiiiittttrrrreeeessssBBBBlllloooocccckkkk))))
Specifies which type of blocking this application
wishes to impose on the editres protocol.
The accepted values are:
all Block all requests.
setValues Block all SetValues requests. As this is the
only editres request that actually modifies
the application, this is in effect stating
that the application is read-only.
none Allow all editres requests.
Remember that these resources are set on any Xaw
application, nnnnooootttt eeeeddddiiiittttrrrreeeessss. They allow individual
applications to keep all or some of the requests editres
makes from ever succeeding. Of course, editres is also an
Xaw application, so it may also be viewed and modified by
editres (rather recursive, I know), these commands can be
blocked by setting the eeeeddddiiiittttrrrreeeessssBBBBlllloooocccckkkk resource on editres
itself.
RRRREEEESSSSOOOOUUUURRRRCCCCEEEESSSS
For _e_d_i_t_r_e_s the available application resources are:
nnnnuuuummmmFFFFllllaaaasssshhhheeeessss ((((Class NNNNuuuummmmFFFFllllaaaasssshhhheeeessss))))
Specifies the number of times the widgets in the
application will be flashed when the SSSShhhhoooowwww AAAAccccttttiiiivvvveeee
WWWWiiiiddddggggeeeettttssss command in invoked.
ffffllllaaaasssshhhhTTTTiiiimmmmeeee ((((Class FFFFllllaaaasssshhhhTTTTiiiimmmmeeee))))
Amount of time between the flashes described above.
ffffllllaaaasssshhhhCCCCoooolllloooorrrr ((((Class ffffllllaaaasssshhhhCCCCoooolllloooorrrr))))
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.
ssssaaaavvvveeeeRRRReeeessssoooouuuurrrrcccceeeessssFFFFiiiilllleeee ((((Class SSSSaaaavvvveeeeRRRReeeessssoooouuuurrrrcccceeeessssFFFFiiiilllleeee))))
This is the file the resource line will be append to

when the SSSSaaaavvvveeee button activated in the resource box.
WWWWIIIIDDDDGGGGEEEETTTTSSSS
In order to specify resources, it is useful to know the
hierarchy of the widgets which compose _e_d_i_t_r_e_s. In the
notation below, indentation indicates hierarchical
structure. The widget class name is given first, followed
by the widget instance name.
