11 * @defgroup Genlist Genlist
13 * The aim was to have more expansive list than the simple list in
14 * Elementary that could have more flexible items and allow many more entries
15 * while still being fast and low on memory usage. At the same time it was
16 * also made to be able to do tree structures. But the price to pay is more
17 * complex when it comes to usage. If all you want is a simple list with
18 * icons and a single label, use the normal List object.
20 * Genlist has a fairly large API, mostly because it's relatively complex,
21 * trying to be both expansive, powerful and efficient. First we will begin
22 * an overview on the theory behind genlist.
24 * Evas tracks every object you create. Every time it processes an event
25 * (mouse move, down, up etc.) it needs to walk through objects and find out
26 * what event that affects. Even worse every time it renders display updates,
27 * in order to just calculate what to re-draw, it needs to walk through many
28 * many many objects. Thus, the more objects you keep active, the more
29 * overhead Evas has in just doing its work. It is advisable to keep your
30 * active objects to the minimum working set you need. Also remember that
31 * object creation and deletion carries an overhead, so there is a
32 * middle-ground, which is not easily determined. But don't keep massive lists
33 * of objects you can't see or use. Genlist does this with list objects. It
34 * creates and destroys them dynamically as you scroll around. It groups them
35 * into blocks so it can determine the visibility etc. of a whole block at
36 * once as opposed to having to walk the whole list. This 2-level list allows
37 * for very large numbers of items to be in the list (tests have used up to
38 * 2,000,000 items). Also genlist employs a queue for adding items. As items
39 * may be different sizes, every item added needs to be calculated as to its
40 * size and thus this presents a lot of overhead on populating the list, this
41 * genlist employs a queue. Any item added is queued and spooled off over
42 * time, actually appearing some time later, so if your list has many members
43 * you may find it takes a while for them to all appear, with your process
44 * consuming a lot of CPU while it is busy spooling.
46 * Genlist also implements a tree structure, but it does so with callbacks to
47 * the application, with the application filling in tree structures when
48 * requested (allowing for efficient building of a very deep tree that could
49 * even be used for file-management). See the above smart signal callbacks for
52 * An item in the genlist world can have 0 or more text labels (they can be
53 * regular text or textblock - that's up to the style to determine), 0 or
54 * more icons (which are simply objects swallowed into the genlist item) and
55 * 0 or more boolean states that can be used for check, radio or other
56 * indicators by the edje theme style. An item may be one of several styles
57 * (Elementary provides 4 by default - "default", "double_label", "group_index"
58 * and "icon_top_text_bottom", but this can be extended by system or
59 * application custom themes/overlays/extensions).
61 * In order to implement the ability to add and delete items on the fly,
62 * Genlist implements a class/callback system where the application provides
63 * a structure with information about that type of item (genlist may contain
64 * multiple different items with different classes, states and styles).
65 * Genlist will call the functions in this struct (methods) when an item is
66 * "realized" (that is created dynamically while scrolling). All objects will
67 * simply be deleted when no longer needed with evas_object_del(). The
68 * Elm_Genlist_Item_Class structure contains the following members:
70 * item_style - This is a constant string and simply defines the name of the
71 * item style. It must be specified and the default should be "default".
73 * func.label_get - This function is called when an actual item object is
74 * created. The data parameter is the data parameter passed to
75 * elm_genlist_item_append() and related item creation functions. The obj
76 * parameter is the genlist object and the part parameter is the string name
77 * of the text part in the edje design that is listed as one of the possible
78 * labels that can be set. This function must return a strudup()'ed string as
79 * the caller will free() it when done.
81 * func.icon_get - This function is called when an actual item object is
82 * created. The data parameter is the data parameter passed to
83 * elm_genlist_item_append() and related item creation functions. The obj
84 * parameter is the genlist object and the part parameter is the string name
85 * of the icon part in the edje design that is listed as one of the possible
86 * icons that can be set. This must return NULL for no object or a valid
87 * object. The object will be deleted by genlist on shutdown or when the item
90 * func.state_get - This function is called when an actual item object is
91 * created. The data parameter is the data parameter passed to
92 * elm_genlist_item_append() and related item creation functions. The obj
93 * parameter is the genlist object and the part parameter is the string name
94 * of the state part in the edje design that is listed as one of the possible
95 * states that can be set. Return 0 for false or 1 for true. Genlist will
96 * emit a signal to the edje object with "elm,state,XXX,active" "elm" when
97 * true (the default is false), where XXX is the name of the part.
99 * func.del - This is called when elm_genlist_item_del() is called on an
100 * item, elm_genlist_clear() is called on the genlist, or
101 * elm_genlist_item_subitems_clear() is called to clear sub-items. This is
102 * intended for use when actual genlist items are deleted, so any backing
103 * data attached to the item (e.g. its data parameter on creation) can be
106 * Items can be added by several calls. All of them return a Elm_Genlist_Item
107 * handle that is an internal member inside the genlist. They all take a data
108 * parameter that is meant to be used for a handle to the applications
109 * internal data (eg the struct with the original item data). The parent
110 * parameter is the parent genlist item this belongs to if it is a tree or
111 * an indexed group, and NULL if there is no parent. The flags can be a bitmask
112 * of ELM_GENLIST_ITEM_NONE, ELM_GENLIST_ITEM_SUBITEMS and
113 * ELM_GENLIST_ITEM_GROUP. If ELM_GENLIST_ITEM_SUBITEMS is set then this item
114 * is displayed as an item that is able to expand and have child items.
115 * If ELM_GENLIST_ITEM_GROUP is set then this item is group idex item that is
116 * displayed at the top until the next group comes. The func parameter is a
117 * convenience callback that is called when the item is selected and the data
118 * parameter will be the func_data parameter, obj be the genlist object and
119 * event_info will be the genlist item.
121 * elm_genlist_item_append() appends an item to the end of the list, or if
122 * there is a parent, to the end of all the child items of the parent.
123 * elm_genlist_item_prepend() is the same but prepends to the beginning of
124 * the list or children list. elm_genlist_item_insert_before() inserts at
125 * item before another item and elm_genlist_item_insert_after() inserts after
126 * the indicated item.
128 * The application can clear the list with elm_genlist_clear() which deletes
129 * all the items in the list and elm_genlist_item_del() will delete a specific
130 * item. elm_genlist_item_subitems_clear() will clear all items that are
131 * children of the indicated parent item.
133 * If the application wants multiple items to be able to be selected,
134 * elm_genlist_multi_select_set() can enable this. If the list is
135 * single-selection only (the default), then elm_genlist_selected_item_get()
136 * will return the selected item, if any, or NULL I none is selected. If the
137 * list is multi-select then elm_genlist_selected_items_get() will return a
138 * list (that is only valid as long as no items are modified (added, deleted,
139 * selected or unselected)).
141 * To help inspect list items you can jump to the item at the top of the list
142 * with elm_genlist_first_item_get() which will return the item pointer, and
143 * similarly elm_genlist_last_item_get() gets the item at the end of the list.
144 * elm_genlist_item_next_get() and elm_genlist_item_prev_get() get the next
145 * and previous items respectively relative to the indicated item. Using
146 * these calls you can walk the entire item list/tree. Note that as a tree
147 * the items are flattened in the list, so elm_genlist_item_parent_get() will
148 * let you know which item is the parent (and thus know how to skip them if
151 * There are also convenience functions. elm_genlist_item_genlist_get() will
152 * return the genlist object the item belongs to. elm_genlist_item_show()
153 * will make the scroller scroll to show that specific item so its visible.
154 * elm_genlist_item_data_get() returns the data pointer set by the item
155 * creation functions.
157 * If an item changes (state of boolean changes, label or icons change),
158 * then use elm_genlist_item_update() to have genlist update the item with
159 * the new state. Genlist will re-realize the item thus call the functions
160 * in the _Elm_Genlist_Item_Class for that item.
162 * To programmatically (un)select an item use elm_genlist_item_selected_set().
163 * To get its selected state use elm_genlist_item_selected_get(). Similarly
164 * to expand/contract an item and get its expanded state, use
165 * elm_genlist_item_expanded_set() and elm_genlist_item_expanded_get(). And
166 * again to make an item disabled (unable to be selected and appear
167 * differently) use elm_genlist_item_disabled_set() to set this and
168 * elm_genlist_item_disabled_get() to get the disabled state.
170 * In general to indicate how the genlist should expand items horizontally to
171 * fill the list area, use elm_genlist_horizontal_mode_set(). Valid modes are
172 * ELM_LIST_LIMIT and ELM_LIST_SCROLL . The default is ELM_LIST_SCROLL. This
173 * mode means that if items are too wide to fit, the scroller will scroll
174 * horizontally. Otherwise items are expanded to fill the width of the
175 * viewport of the scroller. If it is ELM_LIST_LIMIT, items will be expanded
176 * to the viewport width and limited to that size. This can be combined with
177 * a different style that uses edjes' ellipsis feature (cutting text off like
180 * Items will only call their selection func and callback when first becoming
181 * selected. Any further clicks will do nothing, unless you enable always
182 * select with elm_genlist_always_select_mode_set(). This means even if
183 * selected, every click will make the selected callbacks be called.
184 * elm_genlist_no_select_mode_set() will turn off the ability to select
185 * items entirely and they will neither appear selected nor call selected
186 * callback functions.
188 * Remember that you can create new styles and add your own theme augmentation
189 * per application with elm_theme_extension_add(). If you absolutely must
190 * have a specific style that overrides any theme the user or system sets up
191 * you can use elm_theme_overlay_add() to add such a file.
193 * Signals that you can add callbacks for are:
195 * "clicked,double" - This is called when a user has double-clicked an item. The
196 * event_info parameter is the genlist item that was double-c
198 * "selected" - This is called when a user has made an item selected. The
199 * event_info parameter is the genlist item that was selected.
200 * "unselected" - This is called when a user has made an item unselected. The
201 * event_info parameter is the genlist item that was unselected.
202 * "expanded" - This is called when elm_genlist_item_expanded_set() is called
203 * and the item is now meant to be expanded. The event_info
204 * parameter is the genlist item that was indicated to expand. It
205 * is the job of this callback to then fill in the child items.
206 * "contracted" - This is called when elm_genlist_item_expanded_set() is called
207 * and the item is now meant to be contracted. The event_info
208 * parameter is the genlist item that was indicated to contract.
209 * It is the job of this callback to then delete the child items.
210 * "expand,request" - This is called when a user has indicated they want to
211 * expand a tree branch item. The callback should decide if
212 * the item can expand (has any children) and then call
213 * elm_genlist_item_expanded_set() appropriately to set the
214 * state. The event_info parameter is the genlist item that
215 * was indicated to expand.
216 * "contract,request" - This is called when a user has indicated they want to
217 * contract a tree branch item. The callback should decide
218 * if the item can contract (has any children) and then
219 * call elm_genlist_item_expanded_set() appropriately to
220 * set the state. The event_info parameter is the genlist
221 * item that was indicated to contract.
222 * "realized" - This is called when the item in the list is created as a real
223 * evas object. event_info parameter is the genlist item that was
224 * created. The object may be deleted at any time, so it is up to
225 * the caller to not use the object pointer from
226 * elm_genlist_item_object_get() in a way where it may point to
228 * "unrealized" - This is called just before an item is unrealized. After this
229 * call icon objects provided will be deleted and the item object
230 * itself delete or be put into a floating cache.
231 * "drag,start,up" - This is called when the item in the list has been dragged
233 * "drag,start,down" - This is called when the item in the list has been dragged
234 * (not scrolled) down.
235 * "drag,start,left" - This is called when the item in the list has been dragged
236 * (not scrolled) left.
237 * "drag,start,right" - This is called when the item in the list has been
238 * dragged (not scrolled) right.
239 * "drag,stop" - This is called when the item in the list has stopped being
241 * "drag" - This is called when the item in the list is being dragged.
242 * "longpressed" - This is called when the item is pressed for a certain amount
243 * of time. By default it's 1 second.
244 * "scroll,edge,top" - This is called when the genlist is scrolled until the
246 * "scroll,edge,bottom" - This is called when the genlist is scrolled until the
248 * "scroll,edge,left" - This is called when the genlist is scrolled until the
250 * "scroll,edge,right" - This is called when the genlist is scrolled until the
252 * "multi,swipe,left" - This is called when the genlist is multi-touch swiped
254 * "multi,swipe,right" - This is called when the genlist is multi-touch swiped
256 * "multi,swipe,up" - This is called when the genlist is multi-touch swiped up.
257 * "multi,swipe,down" - This is called when the genlist is multi-touch swiped
259 * "multi,pinch,out" - This is called when the genlist is multi-touch pinched
261 * "multi,pinch,in" - This is called when the genlist is multi-touch pinched in.
