Functions

createNativeImage()

bool QGLScreenSurfaceFunctions::createNativeImage ( QImage *  image, EGLNativePixmapType *  native  )

virtual

Creates a native OpenGLES drawable for directly rendering into image and returns it in native.

Since

4.4.2

Returns true if the OpenGLES drawable could be created, or false if direct rendering into images is not supported.

This function will be called if the NativeImages option is set on the screen.

}

createNativePixmap()

bool QGLScreenSurfaceFunctions::createNativePixmap ( QPixmap *  pixmap, EGLNativePixmapType *  native  )

virtual

Creates a native OpenGLES drawable for directly rendering into pixmap and returns it in native.

Since

4.4.2

Returns true if the OpenGLES drawable could be created, or false if direct rendering into pixmaps is not supported.

This function will be called if the NativePixmaps option is set on the screen.

createNativeWindow()

bool QGLScreenSurfaceFunctions::createNativeWindow ( QWidget *  widget, EGLNativeWindowType *  native  )

virtual

Creates a native OpenGLES drawable for the surface of widget and returns it in native.

Since

4.4.2

Returns true if the OpenGLES drawable could be created, or false if windows are not supported.

This function will be called if the NativeWindows option is set on the screen.
