Holds a style sheet.
Library: xviews or winviews or mviews (mutually exclusive)
A style sheet can be attached to one or several IlvStylist
in order to impact the aspect of the IlvStylable
objects they control. Typically, an application will attach a style sheet to a IlvGadgetContainer
to provide a style to the controls it stores.
A style sheet holds a set of Styles. A style is a set of graphical resources that impact a set of objects called Stylable.
Note that IlvStyleSheet
are tracked with reference counting: a counter is increased when this style sheet is attached to a IlvStylist
. This counter is decreased when the style sheet is detached from the stylist. If the object's reference count reaches zero, the style sheet is destroyed.
