OpenGL ES 2.0 Emulator User Guide: 5.2.2. Display initialization

5.2.2. Display initialization

In an OpenGL ES 2.0 application, use the eglGetDisplay call to create a window that displays the rendered output from the Open GL ES 2.0 Emulator. You must pass to this function either the:

value EGL_DEFAULT_DISPLAY
Handle of the Device Context (HDC).

Default display example

Example 5.1 shows a code example that uses the default display:

Example 5.1.

EGLDisplay sEGLDisplay;// EGL init.sEGLDisplay = eglGetDisplay((EGLNativeDisplayType) EGL_DEFAULT_DISPLAY);eglInitialize(sEGLDisplay, NULL, NULL);

Window example

Example 5.2 shows a code example that uses a window display:

Example 5.2.

EGLDisplay sEGLDisplay;

...

// Create windowsWindow = CreateWindowEx(...

// EGL init.sEGLDisplay = eglGetDisplay(GetDC(sWindow));

eglInitialize(sEGLDisplay, NULL, NULL);
