explicit

Constructor.

Parameters

eglDisplay	EGL display connection.
eglConfig	EGL configuration to use.
eglNativeWindow	Window to attach this surface to.

Postcondition

isNoSurface() returns false for this object.

egl::getError() returns EGL_SUCCESS.

EGLWindowSurface() [2/2]

kanzi::EGLWindowSurface::EGLWindowSurface ( ::EGLSurface  eglSurface )

explicit

Constructor.

Parameters

eglSurface

EGL window surface handle.

Postcondition

egl::getError() returns EGL_SUCCESS.

Member Function Documentation

getNoSurface()

static KZ_NO_DISCARD ::EGLSurface kanzi::EGLWindowSurface::getNoSurface ( )

staticnoexcept

Gets an no surface EGL surface handle.

Returns

EGL surface handle with a value representing no surface.

tryCreate()

static KZ_NO_DISCARD optional<EGLWindowSurface> kanzi::EGLWindowSurface::tryCreate ( const EGLDisplay &  eglDisplay, const EGLConfig &  eglConfig, EGLNativeWindowType  eglNativeWindow, const EGLint *  surfaceAttributes  )

staticnoexcept

Creates an EGL window surface.

Parameters

eglDisplay	EGL display connection.
eglConfig	EGL configuration to use.
eglNativeWindow	Window to attach this surface to.
surfaceAttributes	Array of extra attributes.

Return values

nullopt

Surface creation failed.

Returns

The newly created EGL window surface.

destroy()

bool kanzi::EGLWindowSurface::destroy

(

const EGLDisplay &

eglDisplay

)

Destroys EGL window surface.

Call this before destructing the object.

Parameters

eglDisplay

EGL display connection.

Postcondition

egl::getError() returns EGL_SUCCESS.

swapBuffers()

bool kanzi::EGLWindowSurface::swapBuffers

(

const EGLDisplay &

eglDisplay

)

const

Posts rendering results.

Implicitly flushes the rendering pipeline and executes all received rendering commands before posting.

Parameters

eglDisplay

EGL display connection.

See also

swapInterval().

Returns

True on success, false on failure.

Postcondition

egl::getError() returns EGL_SUCCESS.

getNativeHandle()

KZ_NO_DISCARD::EGLSurface kanzi::EGLWindowSurface::getNativeHandle ( ) const

noexcept

Gets EGL window surface handle.

Returns

EGL window surface handle.
