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. 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 difference region. The differences between the files are displayed as high- lighted 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. 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 current 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 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 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 refer- ence. 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 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 appli- cation. 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 class name The application name The entire display, which includes all of the components of the window The main menu bar, which includes the pull-down menus The file selection dialog box for selecting a file to be displayed in the left text display region The file selection dialog box for selecting a file to be displayed in the right text display region The File pull-down menu The Open button on the File menu The Exit button on the File menu The Options pull-down menu The Linked Ver- tical Scrolling On/Off button on the Options menu The Linked Horizontal Scrolling On/Off button on the Options menu The Display Diffs As Lines/Filled Polygons button on the Options menu The Display Line Numbers button on the Options menu The Differences pull-down menu The Do Differences button on the Differences menu The Do Differences In New button on the Differences menu The text region display, which includes both the left and the right text display regions, each of which include the file name bars, the vertical scroll bars, the push button region and the text panes The region where the lines connecting the differences are displayed The file name bars at the top of each text region The vertical scroll bars The region where the file contents are displayed The push button region at the bottom of each text display region The Next Diff push button The Prev Diff push button In addition to the general resources listed in X(1X), the resources available for dxdiff are: Enable or disable linked vertical scrolling.
