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