It can contain an Icon and has a 15 * primary label as well as a units label (that is formatted with floating 16 * point values and thus accepts a printf-style format string, like 17 * “%1.2f units”. There is also an indicator string that may be somewhere 18 * else (like on the slider itself) that also accepts a format string like 19 * units. Label, Icon Unit and Indicator strings/objects are optional. 20 * 21 * A slider may be inverted which means values invert, with high vales being 22 * on the left or top and low values on the right or bottom (as opposed to 23 * normally being low on the left or top and high on the bottom and right). 24 * 25 * The slider should have its minimum and maximum values set by the 26 * application with elm_slider_min_max_set() and value should also be set by 27 * the application before use with elm_slider_value_set(). The span of the 28 * slider is its length (horizontally or vertically). This will be scaled by 29 * the object or applications scaling factor. At any point code can query the 30 * slider for its value with elm_slider_value_get(). 31 * 32 * This widget inherits from the @ref Elm_Layout one, so that all the 33 * functions acting on it also work for slider objects. 34 * 35 * This widget emits the following signals, besides the ones sent from 36 * @ref Elm_Layout : 37 * - @c "changed" - Whenever the slider value is changed by the user. 38 * - @c "slider,drag,start" - dragging the slider indicator around has started. 39 * - @c "slider,drag,stop" - dragging the slider indicator around has stopped. 40 * - @c "delay,changed" - A short time after the value is changed by the user. 41 * This will be called only when the user stops dragging for 42 * a very short period or when they release their 43 * finger/mouse, so it avoids possibly expensive reactions to 44 * the value change. 45 * - @c "focused" - When the slider has received focus. (since 1.8) 46 * - @c "unfocused" - When the slider has lost focus. (since 1.8) 47 * - @c "language,changed" - the program's language changed (since 1.9) 48 * 49 * Available styles for it: 50 * - @c "default" 51 * 52 * Default content parts of the slider widget that you can use for are: 53 * @li "icon" - An icon of the slider 54 * @li "end" - A end part content of the slider 55 * 56 * Default text parts of the slider widget that you can use for are: 57 * @li "default" - A label of the slider 58 * 59 * Supported elm_object common APIs. 60 * @li @ref elm_object_disabled_set 61 * @li @ref elm_object_disabled_get 62 * @li @ref elm_object_part_text_set 63 * @li @ref elm_object_part_text_get 64 * @li @ref elm_object_part_content_set 65 * @li @ref elm_object_part_content_get 66 * @li @ref elm_object_part_content_unset 67 * 68 * Here is an example on its usage: 69 * @li @ref slider_example 70 */ 71 72 /** 73 * @addtogroup Elm_Slider 74 * @{ 75 */ 76 77 #include "elm_slider_common.h" 78 #ifndef EFL_NOLEGACY_API_SUPPORT 79 #include "elm_slider_legacy.h" 80 #endif 81 /** 82 * @} 83 */ 84
