12 * Elementary, besides having the @ref Colorselector widget, exposes its
13 * foundation -- the Elementary Colorselector Class -- in order to create other
14 * widgets which are a colorselector with some more logic on top.

38 * @def ELM_COLORSELECTOR_SMART_CLASS_VERSION

41 * which goes to _Elm_Colorselector_Smart_Class::version.
45 #define ELM_COLORSELECTOR_SMART_CLASS_VERSION 1
48 * @def ELM_COLORSELECTOR_SMART_CLASS_INIT
50 * Initializer for a whole #Elm_Colorselector_Smart_Class structure, with

82 * Initializer to zero out a whole #Elm_Colorselector_Smart_Class structure and
83 * set its name and version.
85 * This is similar to #ELM_COLORSELECTOR_SMART_CLASS_INIT_NULL, but it will
86 * also set the version field of #Elm_Colorselector_Smart_Class (base field)
87 * to the latest #ELM_COLORSELECTOR_SMART_CLASS_VERSION and name it to the

91 * i.e., the name must be available while the structure is
92 * used (hint: static or global variable!) and must not be modified.
