Here is a fork of Gtkdialog by forum member Wiak -"Being a fork with diverged functionality gtkwialog has been given a different code name hence users can choose to use either legacy gtkdialog or this new gtkwialog as they see fit. People who want to run legacy shell/gtkdialog apps that export bash functions, and who do not want to modify them, will want to either continue using legacy gtkdialog or use gtkwialog in legacy mode (which is provided in gtkwialog for backwards compatability)."
