40 * @li @ref ecore_evas_object_example_c
41 * @li @ref ecore_evas_basics_example_c
46 * - iconfication api needs to work
47 * - maximization api needs to work
48 * - document all calls
51 * - buffer back-end that renders to an evas_image_object ???
53 * - dfb back-end ??? (dfb's threads make this REALLY HARD)
61 * @defgroup Ecore_Evas_Group Ecore_Evas wrapper/helper set of functions
63 * This is a list of examples of these functions:

66 * - @ref Ecore_Evas_Buffer_Example_02_c
