       editres - a dynamic resource editor for X Toolkit applications


       editres [ -toolkitoption ... ]


       Editres accepts all of the standard X Toolkit command line options (see
       X(7)).  The order of the command line options is not important.


       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.


       Editres 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 Get Widget Tree 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.


       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 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 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 okay, or type a
               carriage-return.  Editres will now dump the widget tree to this
               file.  To cancel the file dialog, select the cancel 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 Message Area.

       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.


       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 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 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 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  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 flashColor.

              Key     Option                     Translation Entry
              space   Unselect                   Select(nothing)
              w       Select                     Select(widget)
              s       Select                     Select(all)
              i       Invert                     Select(invert)
              c       Select Children            Select(children)
              d       Select Descendants         Select(descendants)
              p       Select Parent              Select(parent)
              a       Select Ancestors           Select(ancestors)
              N       Show Widget Names          Relabel(name)
              C       Show Class Names           Relabel(class)
              I       Show Widget IDs            Relabel(id)
              W       Show Widget Windows        Relabel(window)
              T       Toggle Widget/Class Name   Relabel(toggle)

              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.

       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 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  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

              \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.

       Command Area
              This area contains several command buttons,  described  in  this

       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 okay button.  To  pop
              down  the  dialog  box without changing the save file, click the
              cancel button.

       Save   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 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 resource line 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 Blocking Editres Requests 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.


       The  editres  protocol has been built into the Athena Widget 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 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 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-

       none           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 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 editresBlock resource on editres itself.


       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  in

       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 append to when the
               Save button 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.
