NAME

       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";
	   }

SYNOPSIS

       tk_chooseDirectory ?option value ...?
_________________________________________________________________

DESCRIPTION

       The  procedure tk_chooseDirectory 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.

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

       -parent window
	      Makes window the logical parent of the dialog. The dialog is displayed on top of its parent window. On Mac OS X, this turns the file
	      dialog into a sheet attached to the 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  dis-
	      played.

EXAMPLE

	      set dir [tk_chooseDirectory 
		      -initialdir ~ -title "Choose a directory"]
	      if {$dir eq ""} {
		 label .l -text "No directory selected"
	      } else {
		 label .l -text "Selected $dir"
	      }
