DirTree(3pm) User Contributed Perl Documentation DirTree(3pm)NAMETk::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
