Every MUI object has its own background setting. The background is displayed "behind" the actual object contents, e.g. behind a the text of a text object or behind the image of an image object.

An object without a specific background setting will inherit the pattern from its parent group. The default background for a window and many other background patterns are adjustable with the preferences program.

The following background settings are possible:

• – WindowBack
• – RequesterBack
• – ButtonBack
• – ListBack
• – TextBack
• – PropBack
• – PopupBack
• – SelectedBack
• – RegisterBack
• – GroupBack
• – SliderBack
• – PageBack
• – ReadListBack
• – pre_Background
• – pre_Shadow
• – pre_Shine
• – pre_Fill
• – pre_ShadowBack
• – pre_ShadowFill
• – pre_ShadowShine
• – pre_FillBack
• – pre_FillShine
• – pre_ShineBack
• – pre_FillBack2
• – pre_HshineBack
• – pre_HshadowBack
• – pre_HshineShine
• – pre_HshadowShadow
• – pre_MarkShine
• – pre_MarkHalfshine
• – pre_MarkBackground

All backgrounds with "pre" are MUI's predefined patterns. These are not configurable by the user and will always look the same.

Note: It is *important* that you test your programs with a fancy pattern configuration. With the default setting you won't notice any errors in your backgrounds.
