A resource dictionary is a container that maps resource IDs to resources.
A node can refer to resources by setting resource IDs to resource ID properties. You can set a resource dictionary to the node or to any of its parent nodes to define which resources the node will use. You can use resource dictionary to group similar resources to logical entities like themes or locales, and change a resource dictionary of a node to change multiple resources at the same time.
You can use Node::acquireResource to get the resource from the resource dictionary of a node or from the resource dictionaries of its parent nodes.
A resource dictionary can map resource IDs to resources in these ways: 1) Resource ID can map directly to a resource pointer. 2) Resource ID can map indirectly to a resource with a resource URL. Use acquire and tryAcquire functions to get a mapped resource regardless of the way how a resource ID is mapped to a resource.
You can store nested resource dictionaries in a resource dictionary. When you are getting a resource from a resource dictionary and the resource dictionary cannot find the resource ID you specify, the resource dictionary looks for the resource ID recursively in the nested resource dictionaries.
In a resource dictionary you can store resources without mapping a resource ID to them. In Kanzi Engine such resources are called anonymous resources. You can get anonymous resources with beginAnonymousResources and endAnonymousResources.
To create a resource dictionary:
To add content to a resource dictionary:
To get resources from a resource dictionary:
To change the resource dictionary of a node:
To extend the existing resource dictionary of a node:

ResourceDictionarySharedPtr kanzi::ResourceDictionary::clone | ( | ) | const |
Duplicates a resource dictionary.
When you duplicate a resource dictionary which contains nested resource dictionaries, copies the pointers to the nested resource dictionaries but not the contents of the nested resource dictionaries (i.e. creates a shallow copy). Class that derive from ResourceDictionary must override the cloning implementation in cloneOverride.
