Detailed Description

Manages Overlay objects, parsing them from .overlay files and storing a lookup library of them.

Also manages the creation of OverlayContainers and OverlayElements, used for non-interactive 2D elements such as HUDs.

Member Function Documentation

◆ _queueOverlaysForRendering()

void Ogre::v1::OverlayManager::_queueOverlaysForRendering	(	RenderQueue *	pQueue,
		Viewport *	vp
	)

Internal method for queueing the visible overlays for rendering.

◆ _releaseManualHardwareResources()

void Ogre::v1::OverlayManager::_releaseManualHardwareResources ( )

Notifies that hardware resources were lost.

◆ _restoreManualHardwareResources()

void Ogre::v1::OverlayManager::_restoreManualHardwareResources ( )

Notifies that hardware resources should be restored.

◆ addOverlayElementFactory()

void Ogre::v1::OverlayManager::addOverlayElementFactory ( OverlayElementFactory * elemFactory )

Registers a new OverlayElementFactory with this manager.

Remarks: Should be used by plugins or other apps wishing to provide a new OverlayElement subclass.

◆ cloneOverlayElementFromTemplate()

OverlayElement* Ogre::v1::OverlayManager::cloneOverlayElementFromTemplate	(	const String &	templateName,
		const String &	instanceName
	)

Remarks: Creates a new OverlayElement object from the specified template name. The new object's name, and all of it's children, will be instanceName/orignalName.

◆ create()

Overlay* Ogre::v1::OverlayManager::create ( const String & name )

Create a new Overlay.

◆ createOverlayElement()

OverlayElement* Ogre::v1::OverlayManager::createOverlayElement	(	const String &	typeName,
		const String &	instanceName,
		bool	isTemplate = `false`
	)

Creates a new OverlayElement of the type requested.

Remarks: The type of element to create is passed in as a string because this allows plugins to register new types of component.

Parameters

typeName	The type of element to create.
instanceName	The name to give the new instance.

◆ createOverlayElementFromFactory()

OverlayElement* Ogre::v1::OverlayManager::createOverlayElementFromFactory	(	const String &	typeName,
		const String &	instanceName
	)

◆ createOverlayElementFromTemplate()

OverlayElement* Ogre::v1::OverlayManager::createOverlayElementFromTemplate	(	const String &	templateName,
		const String &	typeName,
		const String &	instanceName,
		bool	isTemplate = `false`
	)

◆ destroy() [1/2]

void Ogre::v1::OverlayManager::destroy ( const String & name )

Destroys an existing overlay by name.

◆ destroy() [2/2]

void Ogre::v1::OverlayManager::destroy ( Overlay * overlay )

Destroys an existing overlay.

◆ destroyAll()

void Ogre::v1::OverlayManager::destroyAll ( )

Destroys all existing overlays.

◆ destroyAllOverlayElements()

void Ogre::v1::OverlayManager::destroyAllOverlayElements ( bool isTemplate = false )

Destroys all the OverlayElement created so far.

Remarks: Best to leave this to the engine to call internally, there should rarely be a need to call it yourself.

◆ destroyOverlayElement() [1/2]

void Ogre::v1::OverlayManager::destroyOverlayElement	(	const String &	instanceName,
		bool	isTemplate = `false`
	)

Destroys a OverlayElement.

Remarks: Make sure you're not still using this in an Overlay. If in doubt, let OGRE destroy elements on shutdown.

◆ destroyOverlayElement() [2/2]

void Ogre::v1::OverlayManager::destroyOverlayElement	(	OverlayElement *	pInstance,
		bool	isTemplate = `false`
	)

Destroys a OverlayElement.

Remarks: Make sure you're not still using this in an Overlay. If in doubt, let OGRE destroy elements on shutdown.

◆ getByName()

Overlay* Ogre::v1::OverlayManager::getByName ( const String & name )

Retrieve an Overlay by name.

Returns: A pointer to the Overlay, or 0 if not found

◆ getLoadingOrder()

Real Ogre::v1::OverlayManager::getLoadingOrder ( ) const

overridevirtual

Gets the relative loading order of scripts of this type.

Remarks: There are dependencies between some kinds of scripts, and to enforce this all implementors of this interface must define a loading order.

Returns: A value representing the relative loading order of these scripts compared to other script users, where higher values load later.

Implements Ogre::ScriptLoader.

◆ getOverlayElement()

OverlayElement* Ogre::v1::OverlayManager::getOverlayElement	(	const String &	name,
		bool	isTemplate = `false`
	)

Gets a reference to an existing element.

◆ getOverlayElementFactoryMap()

const FactoryMap& Ogre::v1::OverlayManager::getOverlayElementFactoryMap ( ) const

inline

Get const access to the list of registered OverlayElement factories.

◆ getOverlayIterator()

OverlayMapIterator Ogre::v1::OverlayManager::getOverlayIterator ( )

◆ getScriptPatterns()

const StringVector& Ogre::v1::OverlayManager::getScriptPatterns ( ) const

overridevirtual

Gets the file patterns which should be used to find scripts for this class.

Remarks: This method is called when a resource group is loaded if you use ResourceGroupManager::_registerScriptLoader.

Returns: A list of file patterns, in the order they should be searched in.

Implements Ogre::ScriptLoader.

◆ getSingleton()

static OverlayManager& Ogre::v1::OverlayManager::getSingleton ( )

static

Override standard Singleton retrieval.

Remarks: Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

: This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

◆ getSingletonPtr()

static OverlayManager* Ogre::v1::OverlayManager::getSingletonPtr ( )

static

Override standard Singleton retrieval.

Remarks: Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

: This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

◆ getTemplateIterator()

TemplateIterator Ogre::v1::OverlayManager::getTemplateIterator ( )

inline

Returns an iterator over all templates in this manager.

◆ getViewportAspectRatio()

Real Ogre::v1::OverlayManager::getViewportAspectRatio ( ) const

◆ getViewportHeight()

int Ogre::v1::OverlayManager::getViewportHeight ( ) const

Gets the height of the destination viewport in pixels.

◆ getViewportWidth()

int Ogre::v1::OverlayManager::getViewportWidth ( ) const

Gets the width of the destination viewport in pixels.

◆ hasOverlayElement()

bool Ogre::v1::OverlayManager::hasOverlayElement	(	const String &	name,
		bool	isTemplate = `false`
	)

Tests if an element exists.

◆ isTemplate()

bool Ogre::v1::OverlayManager::isTemplate ( String strName ) const

inline

◆ parseScript()

void Ogre::v1::OverlayManager::parseScript	(	DataStreamPtr &	stream,
		const String &	groupName
	)

overridevirtual

Parse a script file.

Parameters

stream	Weak reference to a data stream which is the source of the script
groupName	The name of a resource group which should be used if any resources are created during the parse of this script.

Implements Ogre::ScriptLoader.
