"hidden" directories in file selection?

[GRE Spam Mail <gre_spam anora org>]

How can I get the GtkFileSelection window to show "hidden" files and 
directories?

example:

.myprog/        .kde/           .bash_profile           .mynet.conf

(.myprog/ and .kde/ are directories and .bash_profile and .mynet.conf are 
regular files)

Here's my version information:

gtk-config --version
        1.2.10

glib-config --version
        1.2.10

Thank you for your help, in advance.

Sincerely,

GRE
