Detailed Description

A generic datatype for engine specific native surface information.

Please fill up Evas_Native_Surface fields that regarded with current surface type. If you want to set the native surface type to EVAS_NATIVE_SURFACE_X11, you need to set union data with x11.visual or x11.pixmap. If you need to set the native surface as EVAS_NATIVE_SURFACE_OPENGL, on the other hand, you need to set union data with opengl.texture_id or opengl.framebuffer_id and so on. If you need to set the native surface as EVAS_NATIVE_SURFACE_WL, you need to set union data with wl.legacy_buffer. If you need to set the native surface as EVAS_NATIVE_SURFACE_TBM, you need to set union data with tbm surface. The version field should be set with EVAS_NATIVE_SURFACE_VERSION in order to check abi break in your application on the different efl library versions.

Warning:

Native surface types totally depend on the system. Please be aware that the types are supported on your system before using them.

Note:

The information stored in an Evas_Native_Surface returned by evas_gl_native_surface_get() is not meant to be used by applications except for passing it to evas_object_image_native_surface_set().

Since (EFL) :

1.14

unsigned int _Evas_Native_Surface::format

same as 'format' for glTexImage2D()

unsigned int _Evas_Native_Surface::framebuffer_id
