7 * This widget holds 2 content objects(Evas_Object): one on the front and one
8 * on the back. It allows you to flip from front to back and vice-versa using
11 * If either the front or back contents are not set the flip will treat that
12 * as transparent. So if you wore to set the front content but not the back,
13 * and then call elm_flip_go() you would see whatever is below the flip.
15 * For a list of supported animations see elm_flip_go().
17 * Signals that you can add callbacks for are:
18 * "animate,begin" - when a flip animation was started
19 * "animate,done" - when a flip animation is finished
21 * Default contents parts of the flip widget that you can use for are:
22 * @li "front" - A front content of the flip
23 * @li "back" - A back content of the flip
25 * Supported elm_object common APIs.
26 * @li elm_object_part_content_set
27 * @li elm_object_part_content_get
28 * @li elm_object_part_content_unset
30 * @ref tutorial_flip show how to use most of the API.

110 * shown as the other side of the flip.

112 * around a diagonal axis in the middle of its width, the other content is
113 * shown as the other side of the flip.

115 * around a diagonal axis in the middle of its height, the other content is
116 * shown as the other side of the flip.
117 * @li ELM_FLIP_CUBE_LEFT - Rotate the currently visible content to the left
118 * as if the flip was a cube, the other content is show as the right face of

121 * right as if the flip was a cube, the other content is show as the left

124 * flip was a cube, the other content is show as the bottom face of the cube.
125 * @li ELM_FLIP_CUBE_DOWN - Rotate the currently visible content down as if
126 * the flip was a cube, the other content is show as the upper face of the
128 * @li ELM_FLIP_PAGE_LEFT - Move the currently visible content to the left as
129 * if the flip was a book, the other content is shown as the page below that.

144 * @brief Set the interactive flip mode
146 * @param obj The flip object
147 * @param mode The interactive flip mode to use
149 * This sets if the flip should be interactive (allow user to click and
150 * drag a side of the flip to reveal the back page and cause it to flip).
151 * By default a flip is not interactive. You may also need to set which
152 * sides of the flip are "active" for flipping and how much space they use
153 * (a minimum of a finger size) with elm_flip_interaction_direction_enabled_set()
154 * and elm_flip_interaction_direction_hitsize_set()
156 * The four available mode of interaction are:
157 * @li ELM_FLIP_INTERACTION_NONE - No interaction is allowed
158 * @li ELM_FLIP_INTERACTION_ROTATE - Interaction will cause rotate animation
159 * @li ELM_FLIP_INTERACTION_CUBE - Interaction will cause cube animation
160 * @li ELM_FLIP_INTERACTION_PAGE - Interaction will cause page animation
162 * @note ELM_FLIP_INTERACTION_ROTATE won't cause
163 * ELM_FLIP_ROTATE_XZ_CENTER_AXIS or ELM_FLIP_ROTATE_YZ_CENTER_AXIS to
