NAME

       Tk::DirTree - Create and manipulate DirTree widgets

SYNOPSIS

           use Tk::DirTree;

           $dirtree = $parent->DirTree(?options?);

SUPER-CLASS

       The DirTree class is derived from the Tree class and inherits all the methods, options and
       subwidgets of its super-class.

STANDARD OPTIONS

       Tree supports all the standard options of a Tree widget.  See Tk::options for details on
       the standard options.

WIDGET-SPECIFIC OPTIONS

       Name:          browseCmd
       Class:         BrowseCmd
       Switch:        -browsecmd
           Specifies a callback to call whenever the user browses on a directory (usually by
           single-clicking on the name of the directory). The callback is called with one
           argument, the complete pathname of the directory.

       Name:          command
       Class:         Command
       Switch:        -command
           Specifies the callback to be called when the user activates on a directory (usually by
           double-clicking on the name of the directory). The callback is called with one
           argument, the complete pathname of the directory.

       Name:          dircmd
       Class:         DirCmd
       Switch:        -dircmd
           Specifies the callback 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 callback 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 callback returns a list of names of the
           sub-directories of this directory. For example:

               sub read_dir {
                   my( $dir, $showhidden ) = @_;
                   return( qw/DOS NORTON WINDOWS/ ) if $dir eq "C:\\";
                   return();
               }

       Name:          showHidden
       Class:         ShowHidden
       Switch:        -showhidden
           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:          directory
       Class:         Directory
       Switch:        -directory
       Alias:         -value
           Specifies the name of the current directory to be displayed in the DirTree widget.

DESCRIPTION

       The DirTree constructor method creates a new window (given by the $dirtree 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.

WIDGET METHODS

       The DirTree method creates a widget object.  This object supports the configure and cget
       methods described in Tk::options which can be used to enquire and modify the options
       described above.  The widget also inherits all the methods provided by the generic
       Tk::Widget class.

       The following additional methods are available for DirTree widgets:

       $dirtree->chdir(dir)
           Change the current directory to dir.

OTHER METHODS

       These methods have to be documented or made private:

       OpenCmd
       Populate
       add_to_tree
       dirnames
       fullpath
       has_subdir
       opencmd
       set_dir

BINDINGS

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

KEYWORDS

       directory, tree, tix
