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
