Detailed Description

A prefab template contains information that is required to create a tree of Node instances.

The typical workflow for creating nodes in code is to:

Define a prefab template in Kanzi Studio.
Load the exported kzb to the application.
Acquire a prefab template with ResourceManager::acquireResource().
Instantiate a tree of nodes with PrefabTemplate::instantiate().
Add the instantiated nodes to the existing node tree with Node2D::addChild or Node3D::addChild.

Member Function Documentation

template<typename TNodeType >

shared_ptr<TNodeType> kanzi::PrefabTemplate::instantiate ( string_view rootName )

inline

Creates a tree of nodes by instantiating a prefab template node and casts the return value to the target type.

Creates a tree of nodes according to the instructions that are stored in the prefab template data. The returned nodes are initially detached and for them to become active you need to add them to the existing node tree.

Template Parameters

TNodeType The type of the instantiated root node. The type parameter must match the type that is in the prefab template data.

Parameters

rootName The name of the instantiated root node. Overrides the name that is defined in the prefab template data. The child names are not overridden.

Returns: Pointer to the root of the instantiated node tree. If the type parameter does not match the prefab template data, returns nullptr.

NodeSharedPtr kanzi::PrefabTemplate::instantiate ( string_view rootName )

Creates a tree of nodes by instantiating a prefab template.

Creates a tree of nodes according to the instructions that are stored in the prefab template data. The returned nodes are initially detached and for them to become active you need to add them to the existing node tree.

Parameters

rootName The name of the instantiated root node. Overrides the name that is defined in the prefab template data. The child names are not overridden.

Returns: Pointer to the root of the instantiated node tree. If the type parameter does not match the prefab template data, returns nullptr.

template<typename TNodeType >

shared_ptr<TNodeType> kanzi::PrefabTemplate::instantiateAsPart	(	string_view	rootName,
		NodeSharedPtr	templateRoot
	)

inline

Instantiate the prefab where some node other than the root of the prefab is the template root and casts the return value to the target type.

Custom controls use this function to act as template roots for their prefab contents.

Template Parameters

TNodeType The type of the instantiated root node. The type parameter must match the type that is in the prefab template data.

Parameters

rootName	The name of the instantiated root node. Overrides the name that is defined in the prefab template data. The child names are not overridden.
templateRoot	A Pointer to an existing node instance that acts as the template root for the instantiated node tree. Any ##Template bindings in the prefab resolve to this node.

Returns: Pointer to the root of the instantiated node tree. If the type parameter does not match the prefab template data, returns nullptr.

NodeSharedPtr kanzi::PrefabTemplate::instantiateAsPart	(	string_view	rootName,
		NodeSharedPtr	templateRoot
	)

Instantiate the prefab where some node other than the root of the prefab is the template root.

Custom controls use this function to act as template roots for their prefab contents.

Parameters

rootName	The name of the instantiated root node. Overrides the name that is defined in the prefab template data. The child names are not overridden.
templateRoot	A Pointer to an existing node instance that acts as the template root for the instantiated node tree. Any ##Template bindings in the prefab resolve to this node.

Returns: Pointer to the root of the instantiated node tree. If the type parameter does not match the prefab template data, returns nullptr.

static PrefabTemplateSharedPtr kanzi::PrefabTemplate::loadFromKZB	(	Domain *	domain,
		string_view	name,
		KzbFile &	kzbFile,
		ReadOnlyMemoryFile &	file,
		KzbMemoryParser &	parser
	)

static

Loads prefab template from KZB and returns it.

Parameters

domain	Domain.
name	Name of prefab template.
kzbFile	KZB to read prefab template from.
file	File entry in KZB which contains prefab template data.
parser	Parser to parse prefab template data.

Returns: Loaded prefab template.

static PrefabTemplateSharedPtr kanzi::PrefabTemplate::create	(	Domain *	domain,
		PrefabTemplateNodeSharedPtr	rootNode,
		string_view	name
	)

static

Creates a new prefab template.

Parameters

domain	Domain to use.
rootNode	The root template node of the prefab. The rootNode should not be used in any other prefab template.
name	Name of the prefab.

PrefabTemplateNodeSharedPtr kanzi::PrefabTemplate::getRoot ( ) const

inline

Gets the root template node of a prefab.

Returns: The root template node of the prefab.
