NAME

       Tk::chooseDirectory - pops up a dialog box for the user to select a directory.

SYNOPSIS

       $widget->chooseDirectory( ?option value ...? );

DESCRIPTION

       The method chooseDirectory is implemented as a perl wrapper on the core tk "command"
       tk_chooseDirectory, and $widget is passed as the argument to the hidden -parent option.

       The chooseDirectory method pops up a dialog box for the user to select a directory. The
       following option-value pairs are possible as command line arguments:

       -initialdir dirname
           Specifies that the directories in directory should be displayed when the dialog pops
           up. If this parameter is not specified, then the directories in the current working
           directory are displayed. If the parameter specifies a relative path, the return value
           will convert the relative path to an absolute path.  This option may not always work
           on the Macintosh.  This is not a bug. Rather, the General Controls control panel on
           the Mac allows the end user to override the application default directory.

       -parent $widget
           Makes $widget the logical parent of the dialog. The dialog is displayed on top of its
           parent window.

       -title titleString
           Specifies a string to display as the title of the dialog box. If this option is not
           specified, then a default title will be displayed.

       -mustexist boolean
           Specifies whether the user may specify non-existant directories.  If this parameter is
           true, then the user may only select directories that already exist.  The default value
           is false.

CAVEATS

       Perl does not have a concept of encoded filesystems yet. This means that operations on
       filenames like "opendir" and "open" still use byte semantics. Tk however uses character
       semantics internally, which means that you can get filenames with the UTF-8 flag set in
       functions like "chooseDirectory", "getOpenFile" and similar. It's the user's
       responsibility to determine the encoding of the underlying filesystem and convert the
       result into bytes, e.g.

           use Encode;
           ...
           my $dir = $mw->chooseDirectory;
           $dir = encode("windows-1252", $dir);
           opendir DIR, $dir or die $!;
           ...

EXAMPLE

           my $dir = $mw->chooseDirectory(-initialdir => '~',
                                          -title => 'Choose a directory');
           if (!defined $dir) {
               warn 'No directory selected';
           } else {
               warn "Selected $dir";
           }
