Linking windows & dialogs in one taskbar button.

[Glus Xof <gtglus gmail com>]

Hi,

I'd like to ask you for the way (if any) to link all present dialogs
and windows, all in the same one taskbar button, in order to produce
minimize / maximize globally.

I discovered that Gtk::Window::set_skip_taskbar_hint() prevents a
button creation... but the problem is to find the way to link all
these windows/dialogs...

Could be ?
