Window minimization

[Daniel Campos <danielcampos netcourrier com>]

Hello:

 I don't see any way to tell the window manager to now show the
'Minimize' button. With windows forms it easy to add or remove 
maximize, minimize and close buttons from the window decoration.
Is there any way to do it, at least with the more common WM?

 If it is not possible, can I use any event to cancel it before
the window tries to minimize?

Regards,
