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 interafce, with a lot of elements, and will
12 * need to resize or move it frequently (the content object and its
15 * Default contents parts of the mapbuf widget that you can use for are:
16 * @li "default" - A content of the mapbuf
18 * To enable map, elm_mapbuf_enabled_set() should be used.
20 * See how to use this widget in this example:
30 * Add a new mapbuf widget to the given parent Elementary
33 * @param parent The parent object.
34 * @return A new mapbuf widget handle or @c NULL, on errors.
36 * This function inserts a new mapbuf widget on the canvas.
40 EAPI Evas_Object *elm_mapbuf_add(Evas_Object *parent) EINA_ARG_NONNULL(1);
43 * Set the content of the mapbuf.
45 * @param obj The mapbuf object.
46 * @param content The content that will be filled in this mapbuf object.
48 * Once the content object is set, a previously set one will be deleted.
49 * If you want to keep that old content object, use the
50 * elm_mapbuf_content_unset() function.
52 * To enable map, elm_mapbuf_enabled_set() should be used.
54 * @deprecated use elm_object_content_set() instead
58 EINA_DEPRECATED EAPI void elm_mapbuf_content_set(Evas_Object *obj, Evas_Object *content) EINA_ARG_NONNULL(1);
61 * Get the content of the mapbuf.
63 * @param obj The mapbuf object.
64 * @return The content that is being used.
66 * Return the content object which is set for this widget.
68 * @see elm_mapbuf_content_set() for details.
70 * @deprecated use elm_object_content_get() instead
74 EINA_DEPRECATED EAPI Evas_Object *elm_mapbuf_content_get(const Evas_Object *obj) EINA_ARG_NONNULL(1);
77 * Unset the content of the mapbuf.
79 * @param obj The mapbuf object.
80 * @return The content that was being used.
82 * Unparent and return the content object which was set for this widget.
84 * @see elm_mapbuf_content_set() for details.
86 * @deprecated use elm_object_content_unset() instead
90 EINA_DEPRECATED EAPI Evas_Object *elm_mapbuf_content_unset(Evas_Object *obj) EINA_ARG_NONNULL(1);
93 * Enable or disable the map.
95 * @param obj The mapbuf object.
96 * @param enabled @c EINA_TRUE to enable map or @c EINA_FALSE to disable it.
98 * This enables the map that is set or disables it. On enable, the object
99 * geometry will be saved, and the new geometry will change (position and
100 * size) to reflect the map geometry set.
102 * Also, when enabled, alpha and smooth states will be used, so if the
103 * content isn't solid, alpha should be enabled, for example, otherwise
104 * a black retangle will fill the content.
106 * When disabled, the stored map will be freed and geometry prior to
107 * enabling the map will be restored.
109 * It's disabled by default.

119 * Get a value whether map is enabled or not.
121 * @param obj The mapbuf object.
122 * @return @c EINA_TRUE means map is enabled. @c EINA_FALSE indicates
123 * it's disabled. If @p obj is @c NULL, @c EINA_FALSE is returned.

132 * Enable or disable smooth map rendering.
134 * @param obj The mapbuf object.
135 * @param smooth @c EINA_TRUE to enable smooth map rendering or @c EINA_FALSE
138 * This sets smoothing for map rendering. If the object is a type that has
139 * its own smoothing settings, then both the smooth settings for this object
140 * and the map must be turned off.
142 * By default smooth maps are enabled.

164 * @param obj The mapbuf object.
165 * @param alpha @c EINA_TRUE to enable alpha blending or @c EINA_FALSE
168 * This sets alpha flag for map rendering. If the object is a type that has
169 * its own alpha settings, then this will take precedence. Only image objects
170 * have this currently. It stops alpha blending of the map area, and is
171 * useful if you know the object and/or all sub-objects is 100% solid.
