8 * This holds one content object and uses an Evas Map of transformation
9 * points to be later used with this content. So the content will be
10 * moved, resized, etc as a single image. So it will improve performance
11 * when you have a complex interface, with a lot of elements, and will
12 * need to resize or move it frequently (the content object and its
15 * Default content parts of the mapbuf widget that you can use for are:
16 * @li "default" - A content of the mapbuf
18 * Supported elm_object common APIs.
19 * @li elm_object_part_content_set
20 * @li elm_object_part_content_get
21 * @li elm_object_part_content_unset
23 * To enable map, elm_mapbuf_enabled_set() should be used.
25 * See how to use this widget in this example:
35 * Add a new mapbuf widget to the given parent Elementary
38 * @param parent The parent object.
39 * @return A new mapbuf widget handle or @c NULL, on errors.
41 * This function inserts a new mapbuf widget on the canvas.
45 EAPI Evas_Object *elm_mapbuf_add(Evas_Object *parent);
48 * Enable or disable the map.
50 * @param obj The mapbuf object.
51 * @param enabled @c EINA_TRUE to enable map or @c EINA_FALSE to disable it.
53 * This enables the map that is set or disables it. On enable, the object
54 * geometry will be saved, and the new geometry will change (position and
55 * size) to reflect the map geometry set.
57 * Also, when enabled, alpha and smooth states will be used, so if the
58 * content isn't solid, alpha should be enabled, for example, otherwise
59 * a black rectangle will fill the content.
61 * When disabled, the stored map will be freed and geometry prior to
62 * enabling the map will be restored.
64 * It's disabled by default.
66 * @see elm_mapbuf_alpha_set()
67 * @see elm_mapbuf_smooth_set()
71 EAPI void elm_mapbuf_enabled_set(Evas_Object *obj, Eina_Bool enabled);
74 * Get a value whether map is enabled or not.
76 * @param obj The mapbuf object.
77 * @return @c EINA_TRUE means map is enabled. @c EINA_FALSE indicates
78 * it's disabled. If @p obj is @c NULL, @c EINA_FALSE is returned.
80 * @see elm_mapbuf_enabled_set() for details.
84 EAPI Eina_Bool elm_mapbuf_enabled_get(const Evas_Object *obj);
87 * Enable or disable smooth map rendering.
89 * @param obj The mapbuf object.
90 * @param smooth @c EINA_TRUE to enable smooth map rendering or @c EINA_FALSE
93 * This sets smoothing for map rendering. If the object is a type that has
94 * its own smoothing settings, then both the smooth settings for this object
95 * and the map must be turned off.
97 * By default smooth maps are enabled.
101 EAPI void elm_mapbuf_smooth_set(Evas_Object *obj, Eina_Bool smooth);
104 * Get a value whether smooth map rendering is enabled or not.
106 * @param obj The mapbuf object.
107 * @return @c EINA_TRUE means smooth map rendering is enabled. @c EINA_FALSE
108 * indicates it's disabled. If @p obj is @c NULL, @c EINA_FALSE is returned.

114 EAPI Eina_Bool elm_mapbuf_smooth_get(const Evas_Object *obj);
117 * Set or unset alpha flag for map rendering.
119 * @param obj The mapbuf object.
120 * @param alpha @c EINA_TRUE to enable alpha blending or @c EINA_FALSE
123 * This sets alpha flag for map rendering. If the object is a type that has
124 * its own alpha settings, then this will take precedence. Only image objects
125 * have this currently. It stops alpha blending of the map area, and is
126 * useful if you know the object and/or all sub-objects is 100% solid.
128 * Alpha is enabled by default.
132 EAPI void elm_mapbuf_alpha_set(Evas_Object *obj, Eina_Bool alpha);
135 * Get a value whether alpha blending is enabled or not.
137 * @param obj The mapbuf object.
138 * @return @c EINA_TRUE means alpha blending is enabled. @c EINA_FALSE
139 * indicates it's disabled. If @p obj is @c NULL, @c EINA_FALSE is returned.
