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.

Add or divert commands to the decor named decor. A decor is a name given to the set of commands which affect button styles, title-bar styles and border styles. If decor does not exist it is created; otherwise the existing decor is modified. Note: Earlier versions allowed to use the HilightColor, HilightColorset and WindowFont commands in decors. This is no longer possible. Please use the Style command with the Hilight... and Font options.

New decors start out exactly like the "default" decor without any style definitions. A given decor may be applied to a set of windows with the UseDecor option of the Style command. Modifying an existing decor affects all windows which are currently assigned to it.

AddToDecor is similar in usage to the AddToMenu and AddToFunc commands, except that menus and functions are replaced by ButtonStyle, AddButtonStyle, TitleStyle, AddTitleStyle and BorderStyle commands. Decors created with AddToDecor can be manipulated with ChangeDecor, DestroyDecor, UpdateDecor and the Style option.

The following example creates a decor "FlatDecor" and style "FlatStyle". They are distinct entities:

AddToDecor FlatDecor
+ ButtonStyle All Active (-- flat) Inactive (-- flat)
+ TitleStyle  -- flat
+ BorderStyle -- HiddenHandles NoInset

Style FlatStyle \
	UseDecor FlatDecor, HandleWidth 4, ForeColor white, \
	BackColor grey40, HilightFore black, HilightBack grey70

Style xterm UseStyle FlatStyle

An existing window's decor may be reassigned with ChangeDecor. A decor can be destroyed with DestroyDecor.

DestroyDecor FlatDecor
AddToDecor FlatDecor ...

Style FlatStyle UseDecor FlatDecor

and now apply the style again:
