Detailed Description
Contains local style options such as ForegroundOption or FontOption. The default constructor creates an empty container. defaults() returns a container populated with the built-in default options.
bind() associates an inherited container and materializes local partial options against its effective values. find() and get() consider both local and inherited options. findLocal() and hasOptions() only consider locally stored options. set() and reset() modify the local options.

◆ hasOptions()
| bool hasOptions | ( | ) | const |
TODO: remove this in favour of isDefault
◆ bind()
| void bind | ( | const StyleOptions * | inherited | ) |
Rebinding with unchanged local and inherited generations performs no option traversal. Passing 0 removes the inherited container.
