Disclosed is a theme property sheet system that supports presentation themes by coordinating values provided to elements used in a user interface. When an interface user expresses a preference for a particular presentation theme, that theme's property sheet is given precedence over other mechanisms for setting property values. By appropriately setting these values in the interface, the theme property sheet enhances the coherence of the interface. The theme property sheet allows an interface designer to add new presentation elements to a user interface without being concerned about presentation themes. The default for each property as set by the designer is overridden, when necessary, by the theme sheet. In a few particular cases, an application designer needs to override even the user's theme preferences. A mechanism is provided to support these exceptional cases.
