    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.
     

    BINDINGS

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

    KEYWORDS

    directory, tree, tix
