DESCRIPTION
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 differ‐
ence region. The differences between the files are displayed as high‐
lighted text. The differences are connected by lines or filled poly‐
gons across the central difference region. Line numbers are optionally
displayed at each end of the difference lines, to show where the dif‐
ferences occur within the files. Note that the files must be ASCII
text files.
MENUS
The dxdiff window contains the following menus:
File Options Differences Help
File Menu
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 cur‐
rent dxdiff session. If the session is the original one, all other
dxdiff sessions and windows are closed.
Options Menu
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 hori‐
zontal 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 indepen‐
dently 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
The Differences menu contains the following items: Displays the differ‐
ences 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
The Help Menu button invokes a help window that provides information on
dxdiff.
X DEFAULTS
The dxdiff application uses the values in the .Xdefaults 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 .Xdefaults 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. Spec‐
ifies 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 class

components of the window The main menu bar, which includes the pull-
