bool  fullScreen,
const NameValuePairList miscParams = 0 
)
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
nameThe name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
widthThe width of the new window.
heightThe height of the new window.
fullScreenSpecify true to make the window full screen without borders, title bar or menu bar.
miscParamsA 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 Cocoa: OgreGLView address as an integer. You can pass NSView or NSWindow too, but should perform OgreGLView callbacks into the Ogre manually. 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  
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
MSAA Positive integer (usually 0, 2, 4, 8, 16) 0 Full screen antialiasing factor
Android Specific
CSAA Positive integer (usually 0, 2, 4, 8, 16) 0 Coverage sampling factor (https://www.khronos.org/registry/egl/extensions/NV/EGL_NV_coverage_sample.txt)
Android Specific
maxColourBufferSize Positive integer (usually 16, 32) 32 Max EGL_BUFFER_SIZE
Android Specific
minColourBufferSize Positive integer (usually 16, 32) 16 Min EGL_BUFFER_SIZE
Android Specific
maxStencilBufferSize Positive integer (usually 0, 8) 0 EGL_STENCIL_SIZE
Android Specific
maxDepthBufferSize Positive integer (usually 0, 16, 24) 16 EGL_DEPTH_SIZE
