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 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.

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 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 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.

 

Command Area

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 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 ncatest 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.

 

 

editresBlock (Class EditresBlock)

Specifies which type of blocking this application wishes to impose on the editres protocol.

 

numFlashes (Class NumFlashes)

Specifies the number of times the widgets in the application will be flashed when the Show Active Widgets command in 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 append to when the Save button activated in the resource box.

DISPLAY

to get the default host and display number.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

- all

This option indicates that listres should print information for all known widgets and objects.

- nosuper

This option indicates that resources that are inherited from a superclass should not be listed.
This is useful for determining which resources are new to a subclass.

- variable

This option indicates that widgets should be identified by the names of the class record variables rather than the class name given in the variable. This is useful for distinguishing subclasses that have the same class name as their superclasses.

- top name

This option specifies the name of the widget to be treated as the top of the hierarchy. Case is not significant, and the name may match either the class variable name or the class name. The default is "core".

- format printf- string

This option specifies the printf-style format string to be used to print out the name, instance, class, and type of each resource.

 

The kinds of font files read by mkfontdir depend on configuration parameters, but typically include PCF (suffix ".pcf"), SNF (suffix ".snf") and BDF (suffix ".bdf"). If a font exists in multiple formats, mkfontdir will first choose PCF, then SNF and finally BDF.

The first line of fonts.dir gives the number of fonts in the file. The remaining lines list the fonts themselves, one per line, in two fields. First is the name of the font file, followed by a space and the name of the font.

If neither the alias nor the value specifies the size fields of the font name, this is a scalable alias. A font name of any size that matches this alias will be mapped to the same size of the font that the alias resolves to.

When a font alias is used, the name it references is searched for in the normal manner, looking through each font directory in turn. This means that the aliases need not mention fonts in the same directory as the alias file.

To embed white space in either name, simply enclose it in double-quote marks; to embed double-quote marks (or any other character), precede them with back-slash:

"magic-alias with spaces" "" "fontname" with quotes"

If the string "FILE_NAMES_ALIASES" stands alone on a line, each file-name in the directory (stripped of its suffix) will be used as an alias for that font.

- fg color

choose a different color for the both hands and the jewel of the clock

- bg color

choose a different color for the background.

- jewel color

choose a different color for the jewel on the clock.

- minute color

choose a different color for the minute hand of the clock.

- hour color

choose a different color for the hour hand of the clock.

- backing { WhenMapped Always NotUseful }

selects an appropriate level of backing store.

- geometry geometry

define the initial window geometry; see X(1).

- display display

specify the display to use; see X(1).

- bd color

choose a different color for the window border.

- bw width

choose a different width for the window border. As the Clock widget changes its border around quite a bit, this is most usefully set to zero.

- shape

causes the clock to use the Shape extension to create an oval window. This is the default unless the shapeWindow resource is set to false.

- noshape

causes the clock to not reshape itself and ancestors to exactly fit the outline of the clock.

- transparent

causes the clock to consist only of the jewel, the hands, and the border.

This will cause oclock to pick up the colors in the app-defaults color customization file: < XRoot> /lib/X 11/app-defaults/Clock-color. Below are the default colors:

Clock^*Background: grey
Clock^*BorderColor: light blue
Clock^*hour: yellow
Clock^*jewel: yellow
Clock^*minute: yellow

% alias rs 'set noglob; eval 'resize"

$ . /tmp/out

System V has a better interface to /etc/utmp than BSD; it dynamically allocates entries in the file, instead of writing them at fixed positions indexed by position in /etc/ttys.

To manage BSD-style utmp files, sessreg has two strategies. In conjunction with xdm, the -x option counts the number of lines in /etc/ttys and then adds to that the number of the line in the Xservers file which specifies the display. The display name must be specified as the "line-name" using the -l option. This sum is used as the "slot-number" in /etc/utmp that this entry will be written at. In the more general case, the -s option specifies the slot-number directly. If for some strange reason your system uses a file other that /etc/ttys to manage init, the -t option can direct sessreg to look elsewhere for a count of terminal sessions.

Conversely, System V managers will not ever need to use these options (-x, -s and -t). To make the program easier to document and explain, sessreg accepts the BSD-specific flags in the System V environment and ignores them.

BSD also has a host-name field in the utmp file which doesn't exist in System V. This option is also ignored by the System V version of sessreg.

sessreg -a -l $DISPLAY -x /usr/X11R6/lib/xdm/Xservers $USER

sessreg -d -l $DISPLAY -x /usr/X11R6/lib/xdm/Xservers $USER

-w wtmp-file

This specifies an alternate wtmp file, instead of /usr/adm/wtmp for BSD or /etc/wtmp for sysV. The special name "none" disables writing records to /usr/adm/wtmp.

-u utmp-file

This specifies an alternate utmp file, instead of "/etc/utmp". The special name "none" disables writing records to /etc/utmp.

-l line-name

This describes the "line" name of the entry. For terminal sessions, this is the final pathname segment of the terminal device filename (e.g. ttyd0). For X sessions, it should probably be the local display name given to the users session (e.g. :0). If none is specified, the terminal name will be determined with ttyname(3) and stripped of leading components.

-h host-name

This is set for BSD hosts to indicate that the session was initiated from a remote host. In typical xdm usage, this options is not used.

-s slot-number

Each potential session has a unique slot number in BSD systems, most are identified by the position of the line-name in the /etc/ttys file. This option overrides the default position determined with ttyslot(3). This option is inappropriate for use with xdm, the -x option is more useful.

-x Xservers-file

As X sessions are one-per-display, and each display is entered in this file, this options sets the slot-number to be the number of lines in the ttys-file plus the index into this file that the linename is found.

-t ttys-file

This specifies an alternate file which the -x option will use to count the number of terminal sessions on a host.

-a

This session should be added to utmp/wtmp.

-d

This session should be deleted from utmp/wtmp. One of -a/-d must be specified.
