11 * @brief This widget aims to have a more expansive list than the simple list
12 * in Elementary that could have more flexible items and allow many more
13 * entries while still being fast and low on memory usage.
15 * At the same time it was also made to be able to do tree structures. But the
16 * price to pay is based on complexity when it comes to usage. If all you want
17 * is a simple list with icons and a single text, use the normal @ref List
20 * Genlist has a fairly large API, mostly because it's relatively complex,
21 * trying to be expansive, powerful, and efficient. First we begin with
22 * an overview on the theory behind genlist.
24 * This widget inherits from the @ref Layout one, so that all the
25 * functions acting on it also work for genlist objects.
27 * This widget implements the elm-scrollable-interface
28 * interface, so that all (non-deprecated) functions for the base @ref
29 * Scroller widget also work for genlists.
31 * Some calls on the genlist's API are marked as @b deprecated, as
32 * they just wrap the scrollable widgets counterpart functions. Use
33 * the ones mentioned for each case of deprecation here.
34 * Eventually the deprecated ones are discarded (next
37 * @section Genlist_Item_Class Genlist item classes - creating items
39 * In order to have the ability to add and delete items on the fly, genlist
40 * implements a class (callback) system where the application provides a
41 * structure with information about that type of item (genlist may contain
42 * multiple items of different types with different classes, states, and styles).
43 * Genlist calls the functions in this struct (methods) when an item is
44 * "realized" (i.e., created dynamically, while the user is scrolling the
45 * list). All objects are simply deleted when they are no longer needed by
46 * evas_object_del(). The #Elm_Genlist_Item_Class structure contains the
48 * - @c item_style - This is a constant string and simply defines the name
49 * of the item style. It @b must be specified and the default should be @c
52 * - @c decorate_item_style - This is a constant string and simply defines the name
53 * of the decorate mode item style. It is used to specify the decorate mode item style. It can be
54 * used when elm_genlist_item_decorate_mode_set() is called.
55 * - @c decorate_all_item_style - This is a constant string and simply defines the name
56 * of the decorate all item style. It is used to specify the decorate all item style. It can be
57 * used to set the selection, checking, and deletion mode. This is used when
58 * elm_genlist_decorate_mode_set() is called.
60 * - @c func - This is a struct with pointers to functions that are called when
61 * an item is going to actually be created. All of them receive a @c data
62 * parameter that points to the same data that is passed to
63 * elm_genlist_item_append() and other related item creation functions, and an @c
64 * obj parameter that points to the genlist object itself.
66 * The function pointers inside @c func are @c text_get, @c content_get, @c
67 * state_get, and @c del. The first three functions also receive a @c part
68 * parameter described below. A brief description of these functions is as follows:
70 * - @c text_get - The @c part parameter is the name string of one of the
71 * existing text parts in the Edje group implementing the item's theme.
72 * This function @b must return a strdup'()ed string, as the caller is going to
73 * free() it when done. See #Elm_Genlist_Item_Text_Get_Cb.
74 * - @c content_get - The @c part parameter is the name string of one of the
75 * existing (content) swallow parts in the Edje group implementing the item's
76 * theme. It must return @c NULL, when no content is desired, or a valid
77 * object handle, otherwise. The object is deleted by the genlist on
78 * its deletion or when the item is "unrealized".
79 * See #Elm_Genlist_Item_Content_Get_Cb.
80 * - @c func.state_get - The @c part parameter is the name string of one of
81 * the state parts in the Edje group implementing the item's theme. It must return
82 * @c EINA_FALSE for false/off or @c EINA_TRUE for true/on. Genlists
83 * emit a signal to its theming Edje object with @c "elm,state,xxx,active"
84 * and @c "elm" as "emission" and "source" arguments, respectively, when
85 * the state is @c true (the default is false), where @c xxx is the name of
86 * the (state) part. See #Elm_Genlist_Item_State_Get_Cb.
87 * - @c func.del - This is intended for use when genlist items are deleted,
88 * so any data attached to the item (e.g. its data parameter on creation)
89 * can be deleted. See #Elm_Genlist_Item_Del_Cb.
91 * The available item styles are as follows:
93 * - default_style - The text part is a textblock
95 * - icon_top_text_bottom
97 * - one_icon - Only 1 icon (left) @since 1.7
98 * - end_icon - Only 1 icon (at end/right) @since 1.7
99 * - no_icon - No icon (at end/right) @since 1.7
101 * @section Genlist_Items Structure of items
103 * An item in a genlist can have @c 0 or more texts (they can be regular
104 * text or textblock Evas objects - that's up to the style to determine), @c 0
105 * or more blocks of content (which are simply objects swallowed into the genlist item's
106 * theming Edje object) and @c 0 or more <b>boolean states</b>, which have the
107 * behavior left to the user to define. The Edje part names for each of
108 * these properties are looked up, in the theme file for the genlist,
109 * under the Edje (string) data items named @c "labels", @c "contents", and @c
110 * "states", respectively. For each of these properties, if more than one
111 * part is provided, they must have names listed and separated by spaces in the
112 * data fields. For the default genlist item theme, we have @b one text
113 * part (@c "elm.text"), @b two content parts (@c "elm.swalllow.icon" and @c
114 * "elm.swallow.end") and @b no state parts.
116 * A genlist item may be having one of the several styles. Elementary provides one
117 * by default - "default", but this can be extended by system or application
118 * custom themes/overlays/extensions (see @ref Theme "themes" for more
121 * @section Genlist_Manipulation Editing and Navigating
123 * Items can be added by several calls. All of them return a @ref
124 * Elm_Object_Item handle that is an internal member inside the genlist.
125 * They all take a data parameter that is meant to be used as a handle for
126 * the application's internal data (eg. the struct with the original item
127 * data). The parent parameter is the parent genlist item this belongs to if
128 * it is a tree or an indexed group, and this value is @c NULL if there is no parent. The
129 * flags can be a bitmask of #ELM_GENLIST_ITEM_NONE, #ELM_GENLIST_ITEM_TREE,
130 * and #ELM_GENLIST_ITEM_GROUP. If #ELM_GENLIST_ITEM_TREE is set then this
131 * item is displayed as an item that is able to expand and have child items.
132 * If #ELM_GENLIST_ITEM_GROUP is set then this item is a group index item that
133 * is displayed at the top until the next group comes. The @a func parameter is
134 * a convenience callback that is called when the item is selected and the
135 * @a data parameter is the @a func_data parameter, @a obj is the genlist
136 * object, and @a event_info is the genlist item.
138 * elm_genlist_item_append() adds an item to the end of the list, or if
139 * there is a parent, it adds the item to the end of all the child items of the parent.
140 * elm_genlist_item_prepend() is the same but adds an item to the beginning of
141 * the list or children list. elm_genlist_item_insert_before() inserts at
142 * item before another item and elm_genlist_item_insert_after() inserts an item after
143 * the indicated item.
145 * The application can clear the list with elm_genlist_clear() which deletes
146 * all the items in the list. elm_object_item_del() deletes a specific
147 * item. elm_genlist_item_subitems_clear() clears all items that are
148 * children of the indicated parent item.
150 * To help inspect list items you can jump to the item at the top of the list
151 * with elm_genlist_first_item_get() which returns the item pointer. Similarly,
152 * elm_genlist_last_item_get() gets the item at the end of the list.
153 * elm_genlist_item_next_get() and elm_genlist_item_prev_get() get the next
154 * and previous items respectively relative to the indicated item. Using
155 * these calls you can walk through the entire item list/tree. Note that as a tree
156 * the items are flattened in the list, so elm_genlist_item_parent_get()
157 * lets you know which item is the parent (and thus helps you skip them if
160 * @section Genlist_Multi_Selection Multi-selection
162 * If the application wants to allow multiple items to be selected,
163 * elm_genlist_multi_select_set() can enable this. If the list is
164 * single-selection only (the default), then elm_genlist_selected_item_get()
165 * returns the selected item, if any, or @c NULL if none is selected. If the
166 * list is multi-select then elm_genlist_selected_items_get() returns a
167 * list (that is only valid as long as no items are modified (added, deleted,
168 * selected, or unselected)).
170 * @section Genlist_Usage_Hints Usage hints
172 * There are also convenience functions. elm_object_item_widget_get()
173 * returns the genlist object the item belongs to. elm_genlist_item_show()
174 * makes the scroller scroll to show that specific item so that it is visible.
175 * elm_object_item_data_get() returns the data pointer set by the item
176 * creation functions.
178 * If an item changes (state of boolean changes, text or content changes),
179 * then use elm_genlist_item_update() to have genlist update the item with
180 * the new state. Genlist re-realizes the item and thus calls the functions
181 * in the _Elm_Genlist_Item_Class for that item.
183 * To programmatically (un)select an item use elm_genlist_item_selected_set().
184 * To get its selected state use elm_genlist_item_selected_get(). Similarly,
185 * to expand/contract an item and get its expanded state, use
186 * elm_genlist_item_expanded_set() and elm_genlist_item_expanded_get(). And
187 * again to disable an item (unable to be selected and appear
188 * differently) use elm_object_item_disabled_set() to set this and
189 * elm_object_item_disabled_get() to get the disabled state.
191 * In general, to indicate how the genlist should expand items horizontally to
192 * fill the list area, use elm_genlist_mode_set(). Valid modes are
193 * ELM_LIST_LIMIT, ELM_LIST_COMPRESS, and ELM_LIST_SCROLL. The default is
194 * ELM_LIST_SCROLL. This mode means that if items are too wide to fit, the
195 * scroller scrolls horizontally. Otherwise items are expanded to
196 * fill the width of the viewport of the scroller. If it is
197 * ELM_LIST_LIMIT, items are expanded to the viewport width
198 * if the viewport width is larger than the item, but the genlist widget width is
199 * limited to the largest item. Do not use the ELM_LIST_LIMIT mode with the homogenous
200 * mode turned on. ELM_LIST_COMPRESS can be combined with a different style
201 * that uses the edjes' ellipsis feature (cutting text off like this: "tex...").
203 * Items call their selection func and callback only once when selected for the
204 * first time. Any further clicks do nothing, unless you enable always
205 * select with elm_genlist_select_mode_set() as ELM_OBJECT_SELECT_MODE_ALWAYS.
206 * This means even if selected, every click make the selected callbacks
207 * to be called. elm_genlist_select_mode_set() as ELM_OBJECT_SELECT_MODE_NONE
208 * turns off the ability to select items entirely and they neither
209 * appear selected nor call selected callback functions.
211 * Remember that you can create new styles and add your own theme augmentation
212 * for each application with elm_theme_extension_add(). If you absolutely must
213 * have a specific style that overrides any theme that the user or system sets up,
214 * you can use elm_theme_overlay_add() to add such a file.
216 * @section Genlist_Implementation Implementation
218 * Evas tracks every object you create. Every time it processes an event
219 * (mouse move, down, up etc.) it needs to walk through objects and find out
220 * what event they affect. Further, every time it renders display updates,
221 * in order to just calculate what to re-draw, it needs to walk through a large
222 * number of objects. Thus, the more objects you keep active, the more
223 * overhead Evas has in just doing its work. It is advisable to keep your
224 * active objects to the minimum working set you need. Also remember that
225 * object creation and deletion carries an overhead, so there is a
226 * middle-ground, which is not easily determined. But don't keep massive lists
227 * of objects you can't see or use. Genlist does this with list objects. It
228 * creates and destroys them dynamically as you scroll around. It groups them
229 * into blocks so that it can determine the visibility of a whole block at
230 * once as opposed to having to walk through the whole list. This 2-level list allows
231 * for very large numbers of items to be in the list (tests have used upto
232 * 2,000,000 items). Also genlist employs a queue for adding items. As items
233 * maybe of different sizes, every added item needs to be calculated as per its
234 * size and thus this presents a lot of overhead on populating the list, this
235 * genlist employs a queue. Every added item is queued and spooled off over
236 * time, though it appears some time later. So if your list has many members,
237 * you may find that it takes a while for them to appear and this process
238 * consumes a lot of CPU time while it is busy spooling.
240 * Genlist also implements a tree structure for items, but it does so with
241 * callbacks to the application, with the application filling in tree
242 * structures when requested (allowing for efficient building of a very
243 * deep tree that could even be used for file-management).
244 * See the above smart signal callbacks for details.
246 * @section Genlist_Smart_Events Genlist smart events
248 * This widget emits the following signals, besides the ones sent from
250 * - @c "activated" - The user has double-clicked or pressed
251 * (enter|return|spacebar) on an item. The @a event_info parameter is the
