Public Member Functions
	Application (Context *context)
	Construct. Parse default engine parameters from the command line, and create the engine in an uninitialized state.
virtual void	Setup ()
	Setup before engine initialization. This is a chance to eg. modify the engine parameters. Call ErrorExit() to terminate without initializing the engine. Called by Application.
virtual void	Start ()
	Setup after engine initialization and before running the main loop. Call ErrorExit() to terminate without running the main loop. Called by Application.
virtual void	Stop ()
	Cleanup after the main loop. Called by Application.
int	Run ()
	Initialize the engine and run the main loop, then return the application exit code. Catch out-of-memory exceptions while running.
void	ErrorExit (const String &message=String::EMPTY)
	Show an error message (last log message if empty), terminate the main loop, and set failure exit code.
Public Member Functions inherited from Urho3D::Object
	Object (Context *context)
	Construct.
virtual	~Object ()
	Destruct. Clean up self from event sender & receiver structures.
virtual StringHash	GetType () const =0
	Return type hash.
virtual const String &	GetTypeName () const =0
	Return type name.
virtual const TypeInfo *	GetTypeInfo () const =0
	Return type info.
virtual void	OnEvent (Object *sender, StringHash eventType, VariantMap &eventData)
	Handle event.
bool	IsInstanceOf (StringHash type) const
	Check current instance is type of specified type.
bool	IsInstanceOf (const TypeInfo *typeInfo) const
	Check current instance is type of specified type.
template<typename T >
bool	IsInstanceOf () const
	Check current instance is type of specified class.
void	SubscribeToEvent (StringHash eventType, EventHandler *handler)
	Subscribe to an event that can be sent by any sender.
void	SubscribeToEvent (Object *sender, StringHash eventType, EventHandler *handler)
	Subscribe to a specific sender's event.
void	UnsubscribeFromEvent (StringHash eventType)
	Unsubscribe from an event.
void	UnsubscribeFromEvent (Object *sender, StringHash eventType)
	Unsubscribe from a specific sender's event.
void	UnsubscribeFromEvents (Object *sender)
	Unsubscribe from a specific sender's events.
void	UnsubscribeFromAllEvents ()
	Unsubscribe from all events.
void	UnsubscribeFromAllEventsExcept (const PODVector< StringHash > &exceptions, bool onlyUserData)
	Unsubscribe from all events except those listed, and optionally only those with userdata (script registered events.)
void	SendEvent (StringHash eventType)
	Send event to all subscribers.
void	SendEvent (StringHash eventType, VariantMap &eventData)
	Send event with parameters to all subscribers. More...
VariantMap &	GetEventDataMap () const
	Return a preallocated map for event data. Used for optimization to avoid constant re-allocation of event data maps.
Context *	GetContext () const
	Return execution context.
Object *	GetSubsystem (StringHash type) const
	Return subsystem by type.
Object *	GetEventSender () const
	Return active event sender. Null outside event handling.
EventHandler *	GetEventHandler () const
	Return active event handler. Null outside event handling.
bool	HasSubscribedToEvent (StringHash eventType) const
	Return whether has subscribed to an event without specific sender.
bool	HasSubscribedToEvent (Object *sender, StringHash eventType) const
	Return whether has subscribed to a specific sender's event.
bool	HasEventHandlers () const
	Return whether has subscribed to any event.
template<class T >
T *	GetSubsystem () const
	Template version of returning a subsystem.
const String &	GetCategory () const
	Return object category. Categories are (optionally) registered along with the object factory. Return an empty string if the object category is not registered.
Public Member Functions inherited from Urho3D::RefCounted
	RefCounted ()
	Construct. Allocate the reference count structure and set an initial self weak reference.
virtual	~RefCounted ()
	Destruct. Mark as expired and also delete the reference count structure if no outside weak references exist.
void	AddRef ()
	Increment reference count. Can also be called outside of a SharedPtr for traditional reference counting.
void	ReleaseRef ()
	Decrement reference count and delete self if no more references. Can also be called outside of a SharedPtr for traditional reference counting.
int	Refs () const
	Return reference count.
int	WeakRefs () const
	Return weak reference count.
RefCount *	RefCountPtr ()
	Return pointer to the reference count structure.

Protected Member Functions
void	HandleLogMessage (StringHash eventType, VariantMap &eventData)
	Handle log message.

Protected Attributes
SharedPtr< Engine >	engine_
	Urho3D engine.
VariantMap	engineParameters_
	Engine parameters map.
String	startupErrors_
	Collected startup error log messages.
int	exitCode_
	Application exit code.
Protected Attributes inherited from Urho3D::Object

Additional Inherited Members
