Views Styling is based the relationships between three entities:
a Stylable is a visible entity that can use styling to modify its appearance. For instance, the class IlvGadget is a Stylable. This is implemented by the interface class IlvStylable.
a Style Sheet defines values for graphical attributes used to draw Stylable entities. The descriptions of [attribute / value] pairs and the Stylables they apply to are expressed with a style language in an external file. This is implemented by the interface class IlvStyleSheet.
a Stylist serves as intermediary between Style Sheets and Stylables. A Stylist provides an API allowing Stylable objects to obtain the graphical attribute values they request. For instance, the class IlvGadgetContainer is a Stylist. This is implemented by the interface class IlvStylist.
When using Styling, keep the following in mind:
A Stylable relates to only one StylistA Stylist can manage several Style Sheets and are arranged in a hierarchy under a Stylable. The Stylable objects can query their Stylist hierarchy for a potential style to use.The same Style Sheet can be attached to several Stylists.A Stylist may have a parent Stylist. This hierarchy allows you to propagate the effects of a Style Sheet to child entities (also known as style cascading).Published date: 05/24/2022
