Rogue Wave 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.
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 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).
