tk_chooseDirectory ?option value ...?

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:

Specifies the prefix of a Tcl command to invoke when the user closes the dialog after having selected an item. This callback is not called if the user cancelled the dialog. The actual command consists of string followed by a space and the value selected by the user in the dialog. This is only available on macOS.
Specifies that the directories in directory should be displayed when the dialog pops up. If this parameter is not specified, the initial directory defaults to the current working directory on non-Windows systems and on Windows systems prior to Vista. On Vista and later systems, the initial directory defaults to the last user-selected directory for the application. If the parameter specifies a relative path, the return value will convert the relative path to an absolute path.
Specifies a message to include in the client area of the dialog. This is only available on macOS.
Specifies whether the user may specify non-existent directories. If this parameter is true, then the user may only select directories that already exist. The default value is false.
Makes window the logical parent of the dialog. The dialog is displayed on top of its parent window. On macOS, this turns the file dialog into a sheet attached to the parent window.
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.

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