tixDirTree - Create and manipulate tixDirTree widgets

       The mouse and keyboard bindings of the DirTree widget are the same as the bindings of the HList widget.

       The tixDirTree command creates a new window (given by the pathName argument) and makes it into a  DirTree
       widget.   Additional  options,  described  above,  may  be specified on the command line or in the option
       database to configure aspects of the DirTree such as its cursor and relief.

       The DirTree widget displays a list view of a directory, its previous directories and its sub-directories.
       The user can choose one of the directories displayed in the list or change to another directory.

TixDirTree supports all the standard options of a frame widget.  See  the  options(n)  manual  entry  for
       details on the standard options.

       Name:          hlist
       Class:         TixHList

              The hierarchical listbox that displays the directory listing.

       Name:          hsb
       Class:         Scrollbar

              The horizontal scrollbar subwidget.

       Name:          vsb
       Class:         Scrollbar

              The vertical scrollbar subwidget.

       The  TixDirTree  class  is derived from the TixScrolledHList class and inherits all the commands, options
       and subwidgets of its super-class.

tixDirTreepathName ?options?

       The tixDirTree command creates a new Tcl command whose name is the same as the path name of the DirTree's
       window.  This command may be used to invoke various operations  on  the  widget.  It  has  the  following
       general form:
              pathNameoption ?argarg...?
       PathName  is the name of the command, which is the same as the DirTree widget's path name. Option and the
       args determine the exact behavior of the  command.  The  following  commands  are  possible  for  DirTree
       widgets:

       pathNamecgetoption
              Returns  the current value of the configuration option given by option. Option may have any of the
              values accepted by the tixDirTree command.

       pathNamechdirdir
              Change the current directory to dir.

       pathNameconfigure ?option? ?valueoptionvalue...?
              Query or modify the configuration options of the widget.  If no option  is  specified,  returns  a
              list describing all of the available options for pathName (see Tk_ConfigureInfo for information on
              the  format  of  this list). If option is specified with no value, then the command returns a list
              describing the one named option (this list will be identical to the corresponding sublist  of  the
              value  returned if no option is specified).  If one or more option-value pairs are specified, then
              the command modifies the given widget option(s) to have the  given  value(s);  in  this  case  the
              command  returns  an  empty  string.  Option may have any of the values accepted by the tixDirTree
              command.

       pathNamesubwidgetname?args?
              When no options are given, this command returns the pathname of the  subwidget  of  the  specified
              name.

              When  options  are  given, the widget command of the specified subwidget will be called with these
              options.

       [-browsecmdbrowseCmd]  Specifies a command to call whenever the user browses on a directory (usually by
       single-clicking on the name of the directory). The command is called  with  one  argument,  the  complete
       pathname of the directory.  [-commandcommand] Specifies the command to be called when the user activates
       on  a directory (usually by double-clicking on the name of the directory). The command is called with one
       argument, the complete pathname of the directory.  [-dircmddircmd]  Specifies  the  TCL  command  to  be
       called when a directory listing is needed for a particular directory. If this option is not specified, by
       default  the DirTree widget will attempt to read the directory as a Unix directory. On special occasions,
       the application programmer may want to supply a special method for reading directories: for example, when
       he needs to list remote directories. In this case, the -dircmd option can be used. The specified  command
       accepts two arguments: the first is the name of the directory to be listed; the second is a Boolean value
       indicating  whether  hidden sub-directories should be listed. This command returns a list of names of the
       sub-directories of this directory. For example: proc read_dir {dir show_hidden} {
           if {$dir == "C:\"} {
               return {DOS NORTON WINDOWS}
           } else {
               return {}
           } } [-disablecallbackdisableCallback]  A  boolean  value  indicating  whether  callbacks  should  be
       disabled.  When  set  to  true, the TCL command specified by the -command option is not executed when the
       -value of the DirTree widget changes.  [-showhiddenshowHidden]  Specifies  whether  hidden  directories
       should  be  shown.  By  default,  a  directory  name starting with a period "." is considered as a hidden
       directory. This rule can be overridden by supplying an alternative -dircmd option.

       Name:          value
       Class:         Value
       Switch:        -value
       Alias:         -directory

              Specifies the name of the current directory to be displayed in the DirTree widget.
