QPlatformNativeInterface *native =
QGuiApplication::platformNativeInterface();
EGLDisplay egl_display = (EGLDisplay)
native->nativeResourceForWindow("egldisplay", NULL);
However we seem to have no way for getting the EGLNativeDisplayType, aka
native_display, via public API. As such we have to assume that display 0
is always used. Only way around that is parsing the index the same way as
Qt does in QEGLDeviceIntegration::fbDeviceName(), so let's do that.
