Detailed Description

The native rendering context.

An instance of this class is automatically initialized by NativeActivity once the activity's native window has been created, and automatically destroyed when the native window is destroyed. This instance may be obtained by calling NativeActivity::getRenderingContext().

Destructor.

Member Function Documentation

copyBuffer()

bool copyBuffer

(

Pixmap *

pixmap

)

Copy the EGL surface color buffer to a Pixmap.

This is a wrapper around eglCopyBuffers().

getGLVersionMajor()

int getGLVersionMajor ( ) const

inline

Get the OpenGL ES major version number.

getGLVersionMinor()

int getGLVersionMinor ( ) const

inline

Get the OpenGL ES minor version number.

getScreenHeight()

int getScreenHeight ( ) const

inline

Get the height of the screen, in pixels.

getScreenSize()

const Size& getScreenSize ( ) const

inline

Get the size of the screen, in pixels.

getScreenWidth()

int getScreenWidth ( ) const

inline

Get the width of the screen, in pixels.

isValid()

bool isValid ( ) const

inline

Test if this rendering context is valid.

makeCurrent()

void makeCurrent

(

)

Bind this rendering context to the native window.

This is simply a wrapper around eglMakeCurrent().

swapBuffers()

void swapBuffers

(

)

Post the EGL surface to the native window.

This is simply a wrapper around eglSwapBuffers().
