We're trying to build an application which has multiple top
level windows, which we're then trying to group together using
the window manager hints. Our goal is that when we iconify the
"master" window, the other top level window should be iconified
as well.
The first of the following programs creates a top level window and
displays the window ID. The second program, when given the window
ID from the first as a command line parameter, will create another
top level window with the window_group field of the window manager
hints set to the first window.
We've run these programs under mwm (1.1), twm, and olwm on X11R4
on Sun 3 & Sun 4 systems. Iconifying the first window does not
iconify the second window.
Is this a misreading of ICCCM, a bug in the programs, or a problem
with the window managers? If it's a problem with the window managers,
are there any window managers where this works properly? Is this
anywhere in the FAQ (I couldn't find it)?
Thanks for any help!

The general window manager may not even have a concept of "iconifying a window". The ICCCM (Section 4.1.11) specifically leaves it up to the implementor of a window manager to determine the semantics it attaches to the group: "It is up to the window manager to determine the policy for treating the windows in a group." See also Section 4.1.2.4: "Window managers may provide facilities for manipulating the group as a whole. Clients, at present, have no way to operate on the group as a whole." Note the word "may", because it implies also "may not". > We've run these programs under mwm (1.1), twm, and olwm on X11R4 > on Sun 3 & Sun 4 systems.

I don't know if there are existing window managers which implement the policy you want. You have two choices: - If your application will only be run in a controlled environment where you decide which WM gets run, you can hack on your favourite WM and implement the policy you like. - If you want your application to work right with the user's favourite WM, you have to live with the fact that you don't know what its policy about window groups is (this shouldn't stop you providing it with the information about the group, because it will probably do something sensible in the context of its overall user interface policy). I would strongly recommend the second choice - programs that insist on a particular window manager and a particular user interface to window management are much to be deprecated. David.

Currently Mwm 1.1 does not support window groups (may be in a future
version).

A possible work around is to create all of your secondary windows as non-modal dialogs. Then they'll get iconized when the parent window is iconized. -- Alfalfa Software, Inc. | Poste: The EMail for Unix nazgul@alfalfa.com | Send Anything...

This is not a bug of WMs, just missing features. Gwm (on expo, contrib/gwm) will allow you to customize it to design whatever WM policy you have in mind. Just like Emacs, it has a built-in lisp interpreter. For instance, in the default set-up, iconifying an icon will iconify the group, unless the application is in a certain list of applications (Epoch for me). Moreover, the menu has 3 entries for iconifying: "normal" iconifying (only window, or whole group if called on leader) iconify whole group from any window of the group iconify all other windows of the group (very useful) -- Colas Nahaboo, colas@sa.inria.fr, Bull Research, Koala Project, GWM X11 WM Phone:(33) 93.65.77.70(.66 Fax), INRIA, B.P.109 - 06561 Valbonne Cedex, FRANCE.
