tk_chooseDirectory - pops up a dialog box for the user to select a directory.
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:
-initialdirdirname
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.
-parentwindow
Makes window the logical parent of the dialog. The dialog
is displayed on top of its parent window.
-titletitleString
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.
-mustexistboolean
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.
