6 Tk::chooseDirectory - pops up a dialog box for the user to select a
7 directory.
8
10 $widget->chooseDirectory( ?option value ...? );
11
13 The method chooseDirectory is implemented as a perl wrapper on the core
14 tk "command" tk_chooseDirectory, and $widget is passed as the argument
15 to the hidden -parent option.
16
17 The chooseDirectory method pops up a dialog box for the user to select
18 a directory. The following option-value pairs are possible as command
19 line arguments:
20
21 -initialdir dirname
22 Specifies that the directories in directory should be displayed
23 when the dialog pops up. If this parameter is not specified, then
24 the directories in the current working directory are displayed. If
25 the parameter specifies a relative path, the return value will
26 convert the relative path to an absolute path. This option may not
27 always work on the Macintosh. This is not a bug. Rather, the
28 General Controls control panel on the Mac allows the end user to
29 override the application default directory.
30
31 -parent $widget
32 Makes $widget the logical parent of the dialog. The dialog is
33 displayed on top of its parent window.
34
35 -title titleString
36 Specifies a string to display as the title of the dialog box. If
37 this option is not specified, then a default title will be
38 displayed.
39
40 -mustexist boolean
41 Specifies whether the user may specify non-existant directories.
42 If this parameter is true, then the user may only select
43 directories that already exist. The default value is false.

46 Perl does not have a concept of encoded filesystems yet. This means
47 that operations on filenames like "opendir" and "open" still use byte
48 semantics. Tk however uses character semantics internally, which means
49 that you can get filenames with the UTF-8 flag set in functions like
50 "chooseDirectory", "getOpenFile" and similar. It's the user's
51 responsibility to determine the encoding of the underlying filesystem
52 and convert the result into bytes, e.g.
53
54 use Encode;
55 ...
56 my $dir = $mw->chooseDirectory;
57 $dir = encode("windows-1252", $dir);
58 opendir DIR, $dir or die $!;
59 ...

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