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