Detailed Description

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 uses. You can use a resource dictionary to group similar resources to logical entity, such as themes or locales, and change a resource dictionary of a node to change multiple resources at the same time.

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:

Directly to a resource pointer
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.

Examples

To create a resource dictionary:

// Create a resource dictionary.

ResourceDictionarySharedPtr dictionary = ResourceDictionary::create(domain, "Dictionary");

To add content to a resource dictionary:

        // Add resources to a resource dictionary.
        dictionary->add(ResourceID("red icon"), texture);
        dictionary->add(ResourceID("blue icon"), "kzb://my_project/Textures/Blue Icon");

To get resources from a resource dictionary:

        // Acquire resources from a resource dictionary.
        ResourceSharedPtr redIcon = dictionary->acquire(ResourceID("red icon"));
        ResourceSharedPtr blueIcon = dictionary->acquire(ResourceID("blue icon"));

To change the resource dictionary of a node:

// Change the resource dictionary of a node.

node->setResourceDictionary(dictionary);

To extend the existing resource dictionary of a node:

// Extend the existing resource dictionary of a node with a nested resource dictionary.

node->addResourceDictionary(dictionary);

resource The anonymous resource you want to remove from the resource dictionary.

void kanzi::ResourceDictionary::add ( ResourceDictionarySharedPtr resourceDictionary )

Adds a nested resource dictionary to a resource dictionary.

ResourceDictionarySharedPtr kanzi::ResourceDictionary::clone ( ) const

Duplicates a resource dictionary.

When you duplicate a resource dictionary that contains nested resource dictionaries, the function creates a shallow copy: it copies the pointers to the nested resource dictionaries, not the contents of the nested resource dictionaries.

A class that derives from ResourceDictionary must override the cloning implementation in cloneOverride.

Returns: The pointer to the duplicated resource dictionary.
