font is times_bold12. Specifies the width, length, and
location of the dxdiff window. If the geometry option is
not specified, dxdiff uses default values. The geometry
option has the format [widthxlength][{+-}x{+-}y]. For more
information about the screen coordinate system, see X(1X).
Disables linked vertical scrolling. Enables linked vertical
scrolling. This is the default. Disables linked horizontal
scrolling Enables linked horizontal scrolling. This
is the default. Enables the display of filled polygons to
connect areas of different text. This is the default.
Enables the display of lines to connect areas of different
text. Disables the display of line numbers in the difference
region. Enables the display of line numbers in the
difference region. This is the default. Specifies the
foreground color for the line numbers in the difference
box. The default is black.
Specifies the two files that are to be opened at startup.
If you do not specify any file names, dxdiff lets you
specify files after it has started up.
The dxdiff application does a line-by-line comparison of
two files and displays the differences between them. The
contents of the two files are displayed in two text
regions on either side of a central difference region. The
differences between the files are displayed as highlighted
text. The differences are connected by lines or filled
polygons across the central difference region. Line numbers
are optionally displayed at each end of the difference
lines, to show where the differences occur within the
files. Note that the files must be ASCII text files.
The dxdiff window contains the following menus: File
Options Differences Help
File Menu [Toc] [Back]
The dxdiff File menu contains the following menu items:
Calls up two Open... dialog boxes, to allow you to specify
the two files that you want to compare. The dialog boxes
are labeled Left File and Right File. You must select one
file from each dialog box. Exits the current dxdiff session.
If the session is the original one, all other dxdiff
sessions and windows are closed.
Options Menu [Toc] [Back]
The Options menu contains the following menu items: The
default is linked vertical scrolling. When linked vertical
scrolling is on and you scroll one of the files, the
other file is scrolled with it line for line. When linked
vertical scrolling is off, one file can be scrolled independently
of the other one. The default is linked horizontal
scrolling. When linked horizontal scrolling is on
and you scroll one of the files, the other file is
scrolled with it. When linked horizontal scrolling is
off, one file can be scrolled independently of the other
one. Displays either lines or filled polygons to connect
the differences across the difference box. The default on
startup is for filled polygons to be displayed. Displays
line numbers at each end of the lines that connect the
differences. The default is to display line numbers. If
dxdiff cannot find a suitable font size for displaying the
line numbers, this item is disabled.
Differences Menu [Toc] [Back]
The Differences menu contains the following items: Displays
the differences between the two currently selected
files. Opens a new dxdiff window to display the differences
between the two currently selected files. The
existing dxdiff window remains on the screen for reference.
Help Menu [Toc] [Back]
The Help Menu button invokes a help window that provides
information on dxdiff.
The dxdiff application uses the values in the file when
you logged in and uses the appropriate resource specification
to customize the appearance or characteristics of its
displayed dxdiff window. The format for a resource specification
in the file is:
[*name*]resource: value
Specifies the application name or the name string that
restricts the resource assignment to that application or
to a component of an application. If this argument is not
specified, the resource assignment is globally available
to all X applications. Specifies the resource. Specifies
the value that is to be assigned to the resource.
For more information, see X(1X).
Because each toolkit-based application can consist of a
combination of widgets (for example, push buttons and a
scroll bar), you can form the name string by adding widget
class and name identifiers to the string. For further
information about adding class and name identifiers, see
X(1X).
For dxdiff, the available class identifiers are: XmLabel
XmPushButton XmRowColumn XmScrollbar XmText
For dxdiff, the available name identifiers are: The application

which includes all of the components of the window The
