		unsigned int	width,
		unsigned int	height,
		bool	fullScreen,
		const NameValuePairList *	miscParams = `0`
	)		`[pure virtual]`

Creates a new rendering window.

Remarks:: This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation.

: After creation, this window can be retrieved using getRenderTarget().

Parameters:

name The name of the window. Used in other methods later like setRenderTarget and getRenderTarget.

width The width of the new window.

height The height of the new window.

fullScreen Specify true to make the window full screen without borders, title bar or menu bar.

miscParams

A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platforms unless indicated otherwise:

Key	Type/Values	Default	Description	Notes
title	Any string	RenderTarget name	The title of the window that will appear in the title bar
colourDepth	16, 32	Desktop depth	Colour depth of the resulting rendering window; only applies if fullScreen	Win32 Specific
left	Positive integers	Centred	Screen x coordinate from left
top	Positive integers	Centred	Screen y coordinate from left
depthBuffer	true, false	true	Use depth buffer	DirectX9 specific
externalWindowHandle	Win32: HWND as integer GLX: poslong:posint:poslong (display:screen:windowHandle) or poslong:posint:poslong:poslong (display:screen:windowHandle:XVisualInfo*) OS X: WindowRef for Carbon or NSWindow for Cocoa address as an integer iOS: UIWindow address as an integer	0 (none)	External window handle, for embedding the OGRE render in an existing window
externalGLControl	true, false	false	Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls.	OpenGL specific
externalGLContext	Context as Unsigned Long	0 (create own context)	Use an externally created GL context	OpenGL Specific
parentWindowHandle	Win32: HWND as integer GLX: poslong:posint:poslong (display:screen:windowHandle) or poslong:posint:poslong:poslong (display:screen:windowHandle:XVisualInfo*)	0 (none)	Parent window handle, for embedding the OGRE in a child of an external window
macAPI	String: "cocoa" or "carbon"	"carbon"	Specifies the type of rendering window on the Mac Platform.	Mac OS X Specific
macAPICocoaUseNSView	bool "true" or "false"	"false"	On the Mac platform the most diffused method to embed OGRE in a custom application is to use Interface Builder and add to the interface an instance of OgreView. The pointer to this instance is then used as "externalWindowHandle". However, there are cases where you are NOT using Interface Builder and you get the Cocoa NSView* of an existing interface. For example, this is happens when you want to render into a Java/AWT interface. In short, by setting this flag to "true" the Ogre::Root::createRenderWindow interprets the "externalWindowHandle" as a NSView* instead of an OgreView*. See OgreOSXCocoaView.h/mm.	Mac OS X Specific
contentScalingFactor	Positive Float greater than 1.0	The default content scaling factor of the screen	Specifies the CAEAGLLayer content scaling factor. Only supported on iOS 4 or greater. This can be useful to limit the resolution of the OpenGL ES backing store. For example, the iPhone 4's native resolution is 960 x 640. Windows are always 320 x 480, if you would like to limit the display to 720 x 480, specify 1.5 as the scaling factor.	iOS Specific
externalViewHandle	UIView pointer as an integer	0	External view handle, for rendering OGRE render in an existing view	iOS Specific
externalViewControllerHandle	UIViewController pointer as an integer	0	External view controller handle, for embedding OGRE in an existing view controller	iOS Specific
externalSharegroup	EAGLSharegroup pointer as an integer	0	External sharegroup, used to shared GL resources between contexts	iOS Specific
Full Screen	true, false	false	Specify whether to create the window in full screen mode	OS X Specific
FSAA	Positive integer (usually 0, 2, 4, 8, 16)	0	Full screen antialiasing factor
FSAAHint	Depends on RenderSystem and hardware. Currently supports: "Quality": on systems that have an option to prefer higher AA quality over speed, use it	Blank	Full screen antialiasing hint
displayFrequency	Refresh rate in Hertz (e.g. 60, 75, 100)	Desktop vsync rate	Display frequency rate, for fullscreen mode
vsync	true, false	false	Synchronize buffer swaps to monitor vsync, eliminating tearing at the expense of a fixed frame rate
vsyncInterval	1, 2, 3, 4	1	If vsync is enabled, the minimum number of vertical blanks that should occur between renders. For example if vsync is enabled, the refresh rate is 60 and this is set to 2, then the frame rate will be locked at 30.
border	none, fixed, resize	resize	The type of window border (in windowed mode)
outerDimensions	true, false	false	Whether the width/height is expressed as the size of the outer window, rather than the content area
useNVPerfHUD	true, false	false	Enable the use of nVidia NVPerfHUD
gamma	true, false	false	Enable hardware conversion from linear colour space to gamma colour space on rendering to the window.
enableDoubleClick	true, false	false	Enable the window to keep track and transmit double click messages.	Win32 Specific
