The XDISPLAYFILE procedure displays an ASCII text file using a widget interface.
This routine is written in the IDL language. Its source code can be found in the file
subdirectory of the IDL distribution.
Set this keyword to have XMANAGER block when this application is registered. By default, BLOCK is set equal to zero, providing access to the command line if active command line processing is available. Note that setting BLOCK=1 will cause all widget applications to block, not just this application. For more information, see the documentation for the NO_BLOCK keyword to XMANAGER .
A string containing the name of the font to use. The font specified is a "device font" (an X Windows font on Motif systems; a TrueType or PostScript font on Windows or Macintosh systems). See for details on specifying names for device fonts. If this keyword is omitted, the default font is used.
A string or string array to be displayed in the widget instead of the contents of a file. If this keyword is present, the Filename input argument is ignored (but is still required). String arrays are displayed one element per line.
