This command is deprecated and will be removed in the future. There are plans to replace it with a more flexible solution in fvwm-3.0.

This command is kept mainly for backward compatibility. Since all elements of a decor are updated immediately when they are changed, this command is mostly useless.

Updates window decorations. decor is an optional argument which specifies the decor to update. If given, only windows which are assigned to that particular decor are updated. This command is useful, for instance, after a ButtonStyle, TitleStyle or BorderStyle (possibly used in conjunction with AddToDecor). Specifying an invalid decor results in all windows being updated. This command is less disturbing than Recapture, but does not affect window style options as Recapture does.
