   9  * @defgroup Genlist Genlist
  10  *
  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.
  17  *
  18  * Genlist has a fairly large API, mostly because it's relatively complex,
  19  * trying to be both expansive, powerful and efficient. First we will begin
  20  * an overview on the theory behind genlist.
  21  *
  22  * Evas tracks every object you create. Every time it processes an event
  23  * (mouse move, down, up etc.) it needs to walk through objects and find out
  24  * what event that affects. Even worse every time it renders display updates,
  25  * in order to just calculate what to re-draw, it needs to walk through many
  26  * many many objects. Thus, the more objects you keep active, the more
  27  * overhead Evas has in just doing its work. It is advisable to keep your
  28  * active objects to the minimum working set you need. Also remember that
  29  * object creation and deletion carries an overhead, so there is a
  30  * middle-ground, which is not easily determined. But don't keep massive lists
  31  * of objects you can't see or use. Genlist does this with list objects. It
  32  * creates and destroys them dynamically as you scroll around. It groups them
  33  * into blocks so it can determine the visibility etc. of a whole block at
  34  * once as opposed to having to walk the whole list. This 2-level list allows
  35  * for very large numbers of items to be in the list (tests have used up to
  36  * 2,000,000 items). Also genlist employs a queue for adding items. As items
  37  * may be different sizes, every item added needs to be calculated as to its
  38  * size and thus this presents a lot of overhead on populating the list, this
  39  * genlist employs a queue. Any item added is queued and spooled off over
  40  * time, actually appearing some time later, so if your list has many members
  41  * you may find it takes a while for them to all appear, with your process
  42  * consuming a lot of CPU while it is busy spooling.
  43  *
  44  * Genlist also implements a tree structure, but it does so with callbacks to
  45  * the application, with the application filling in tree structures when
  46  * requested (allowing for efficient building of a very deep tree that could
  47  * even be used for file-management). See the above smart signal callbacks for
  48  * details.
  49  *
  50  * An item in the genlist world can have 0 or more text labels (they can be
  51  * regular text or textblock - that's up to the style to determine), 0 or
  52  * more icons (which are simply objects swallowed into the genlist item) and
  53  * 0 or more boolean states that can be used for check, radio or other
  54  * indicators by the edje theme style. An item may be one of several styles
  55  * (Elementary provides 4 by default - "default", "double_label", "group_index"
  56  * and "icon_top_text_bottom", but this can be extended by system or
  57  * application custom themes/overlays/extensions).
  58  *
  59  * In order to implement the ability to add and delete items on the fly,
  60  * Genlist implements a class/callback system where the application provides
  61  * a structure with information about that type of item (genlist may contain
  62  * multiple different items with different classes, states and styles).
  63  * Genlist will call the functions in this struct (methods) when an item is
  64  * "realized" (that is created dynamically while scrolling). All objects will
  65  * simply be deleted  when no longer needed with evas_object_del(). The
  66  * Elm_Genlist_Item_Class structure contains the following members:
  67  *
  68  * item_style - This is a constant string and simply defines the name of the
  69  * item style. It must be specified and the default should be "default".
  70  *
  71  * func.label_get - This function is called when an actual item object is
  72  * created. The data parameter is the data parameter passed to
  73  * elm_genlist_item_append() and related item creation functions. The obj
  74  * parameter is the genlist object and the part parameter is the string name
  75  * of the text part in the edje design that is listed as one of the possible
  76  * labels that can be set. This function must return a strudup()'ed string as
  77  * the caller will free() it when done.
  78  *
  79  * func.icon_get - This function is called when an actual item object is
  80  * created. The data parameter is the data parameter passed to
  81  * elm_genlist_item_append() and related item creation functions. The obj
  82  * parameter is the genlist object and the part parameter is the string name
  83  * of the icon part in the edje design that is listed as one of the possible
  84  * icons that can be set. This must return NULL for no object or a valid
  85  * object. The object will be deleted by genlist on shutdown or when the item
  86  * is unrealized.
  87  *
  88  * func.state_get - This function is called when an actual item object is
  89  * created. The data parameter is the data parameter passed to
  90  * elm_genlist_item_append() and related item creation functions. The obj
  91  * parameter is the genlist object and the part parameter is the string name
  92  * of the state part in the edje design that is listed as one of the possible
  93  * states that can be set. Return 0 for false or 1 for true. Genlist will
  94  * emit a signal to the edje object with "elm,state,XXX,active" "elm" when
  95  * true (the default is false), where XXX is the name of the part.
  96  *
  97  * func.del - This is called when elm_genlist_item_del() is called on an
  98  * item, elm_genlist_clear() is called on the genlist, or
  99  * elm_genlist_item_subitems_clear() is called to clear sub-items. This is
 100  * intended for use when actual genlist items are deleted, so any backing
 101  * data attached to the item (e.g. its data parameter on creation) can be
 102  * deleted.
 103  *
 104  * Items can be added by several calls. All of them return a Elm_Genlist_Item
 105  * handle that is an internal member inside the genlist. They all take a data
 106  * parameter that is meant to be used for a handle to the applications
 107  * internal data (eg the struct with the original item data). The parent
 108  * parameter is the parent genlist item this belongs to if it is a tree or
 109  * an indexed group, and NULL if there is no parent. The flags can be a bitmask
 110  * of ELM_GENLIST_ITEM_NONE, ELM_GENLIST_ITEM_SUBITEMS and
 111  * ELM_GENLIST_ITEM_GROUP. If ELM_GENLIST_ITEM_SUBITEMS is set then this item
 112  * is displayed as an item that is able to expand and have child items.
 113  * If ELM_GENLIST_ITEM_GROUP is set then this item is group idex item that is
 114  * displayed at the top until the next group comes. The func parameter is a
 115  * convenience callback that is called when the item is selected and the data
 116  * parameter will be the func_data parameter, obj be the genlist object and
 117  * event_info will be the genlist item.
 118  *
 119  * elm_genlist_item_append() appends an item to the end of the list, or if
 120  * there is a parent, to the end of all the child items of the parent.
 121  * elm_genlist_item_prepend() is the same but prepends to the beginning of
 122  * the list or children list. elm_genlist_item_insert_before() inserts at
 123  * item before another item and elm_genlist_item_insert_after() inserts after
 124  * the indicated item.
 125  *
 126  * The application can clear the list with elm_genlist_clear() which deletes
 127  * all the items in the list and elm_genlist_item_del() will delete a specific
 128  * item. elm_genlist_item_subitems_clear() will clear all items that are
 129  * children of the indicated parent item.
 130  *
 131  * If the application wants multiple items to be able to be selected,
 132  * elm_genlist_multi_select_set() can enable this. If the list is
 133  * single-selection only (the default), then elm_genlist_selected_item_get()
 134  * will return the selected item, if any, or NULL I none is selected. If the
 135  * list is multi-select then elm_genlist_selected_items_get() will return a
 136  * list (that is only valid as long as no items are modified (added, deleted,
 137  * selected or unselected)).
 138  *
 139  * To help inspect list items you can jump to the item at the top of the list
 140  * with elm_genlist_first_item_get() which will return the item pointer, and
 141  * similarly elm_genlist_last_item_get() gets the item at the end of the list.
 142  * elm_genlist_item_next_get() and elm_genlist_item_prev_get() get the next
 143  * and previous items respectively relative to the indicated item. Using
 144  * these calls you can walk the entire item list/tree. Note that as a tree
 145  * the items are flattened in the list, so elm_genlist_item_parent_get() will
 146  * let you know which item is the parent (and thus know how to skip them if
 147  * wanted).
 148  *
 149  * There are also convenience functions. elm_genlist_item_genlist_get() will
 150  * return the genlist object the item belongs to. elm_genlist_item_show()
 151  * will make the scroller scroll to show that specific item so its visible.
 152  * elm_genlist_item_data_get() returns the data pointer set by the item
 153  * creation functions.
 154  *
 155  * If an item changes (state of boolean changes, label or icons change),
 156  * then use elm_genlist_item_update() to have genlist update the item with
 157  * the new state. Genlist will re-realize the item thus call the functions
 158  * in the _Elm_Genlist_Item_Class for that item.
 159  *
 160  * To programmatically (un)select an item use elm_genlist_item_selected_set().
 161  * To get its selected state use elm_genlist_item_selected_get(). Similarly
 162  * to expand/contract an item and get its expanded state, use
 163  * elm_genlist_item_expanded_set() and elm_genlist_item_expanded_get(). And
 164  * again to make an item disabled (unable to be selected and appear
 165  * differently) use elm_genlist_item_disabled_set() to set this and
 166  * elm_genlist_item_disabled_get() to get the disabled state.
 167  *
 168  * In general to indicate how the genlist should expand items horizontally to
 169  * fill the list area, use elm_genlist_horizontal_mode_set(). Valid modes are
 170  * ELM_LIST_LIMIT and ELM_LIST_SCROLL . The default is ELM_LIST_SCROLL. This
 171  * mode means that if items are too wide to fit, the scroller will scroll
 172  * horizontally. Otherwise items are expanded to fill the width of the
 173  * viewport of the scroller. If it is ELM_LIST_LIMIT, items will be expanded
 174  * to the viewport width and limited to that size. This can be combined with
 175  * a different style that uses edjes' ellipsis feature (cutting text off like
 176  * this: "tex...").
 177  *
 178  * Items will only call their selection func and callback when first becoming
 179  * selected. Any further clicks will do nothing, unless you enable always
 180  * select with elm_genlist_always_select_mode_set(). This means even if
 181  * selected, every click will make the selected callbacks be called.
 182  * elm_genlist_no_select_mode_set() will turn off the ability to select
 183  * items entirely and they will neither appear selected nor call selected
 184  * callback functions.
 185  *
 186  * Remember that you can create new styles and add your own theme augmentation
 187  * per application with elm_theme_extension_add(). If you absolutely must
 188  * have a specific style that overrides any theme the user or system sets up
 189  * you can use elm_theme_overlay_add() to add such a file.
 190  *
 191  * Signals that you can add callbacks for are:
 192  *
 193  * "clicked,double" - This is called when a user has double-clicked an item. The
 194  *                    event_info parameter is the genlist item that was double-c
 195  *                    licked.
 196  * "selected" - This is called when a user has made an item selected. The
 197  *              event_info parameter is the genlist item that was selected.
 198  * "unselected" - This is called when a user has made an item unselected. The
 199  *                 event_info parameter is the genlist item that was unselected.
 200  * "expanded" - This is called when elm_genlist_item_expanded_set() is called
 201  *              and the item is now meant to be expanded. The event_info
 202  *              parameter is the genlist item that was indicated to expand. It
 203  *              is the job of this callback to then fill in the child items.
 204  * "contracted" - This is called when elm_genlist_item_expanded_set() is called
 205  *                and the item is now meant to be contracted. The event_info
 206  *                parameter is the genlist item that was indicated to contract.
 207  *                It is the job of this callback to then delete the child items.
 208  * "expand,request" - This is called when a user has indicated they want to
 209  *                    expand a tree branch item. The callback should decide if
 210  *                    the item can expand (has any children) and then call
 211  *                    elm_genlist_item_expanded_set() appropriately to set the
 212  *                    state. The event_info parameter is the genlist item that
 213  *                    was indicated to expand.
 214  * "contract,request" - This is called when a user has indicated they want to
 215  *                      contract a tree branch item. The callback should decide
 216  *                      if the item can contract (has any children) and then
 217  *                      call elm_genlist_item_expanded_set() appropriately to
 218  *                      set the state. The event_info parameter is the genlist
 219  *                      item that was indicated to contract.
 220  * "realized" - This is called when the item in the list is created as a real
 221  *              evas object. event_info parameter is the genlist item that was
 222  *              created. The object may be deleted at any time, so it is up to
 223  *              the caller to not use the object pointer from
 224  *              elm_genlist_item_object_get() in a way  where it may point to
 225  *              freed objects.
 226  * "unrealized" - This is called just before an item is unrealized. After this
 227  *                call icon objects provided will be deleted and the item object
 228  *                itself delete or be put into a floating cache.
 229  * "drag,start,up" - This is called when the item in the list has been dragged
 230  *                   (not scrolled) up.
 231  * "drag,start,down" - This is called when the item in the list has been dragged
 232  *                     (not scrolled) down.
 233  * "drag,start,left" - This is called when the item in the list has been dragged
 234  *                     (not scrolled) left.
 235  * "drag,start,right" - This is called when the item in the list has been
 236  *                      dragged (not scrolled) right.
 237  * "drag,stop" - This is called when the item in the list has stopped being
 238  *               dragged.
 239  * "drag" - This is called when the item in the list is being dragged.
 240  * "longpressed" - This is called when the item is pressed for a certain amount
 241  *                 of time. By default it's 1 second.
 242  * "scroll,edge,top" - This is called when the genlist is scrolled until the
 243  *                     top edge.
 244  * "scroll,edge,bottom" - This is called when the genlist is scrolled until the
 245  *                         bottom edge.
 246  * "scroll,edge,left" - This is called when the genlist is scrolled until the
 247  *                      left edge.
 248  * "scroll,edge,right" - This is called when the genlist is scrolled until the
 249  *                       right edge.
 250  * "multi,swipe,left" - This is called when the genlist is multi-touch swiped
 251  *                       left.
 252  * "multi,swipe,right" - This is called when the genlist is multi-touch swiped
 253  *                       right.
 254  * "multi,swipe,up" - This is called when the genlist is multi-touch swiped up.
 255  * "multi,swipe,down" - This is called when the genlist is multi-touch swiped
 256  *                      down.
 257  * "multi,pinch,out" - This is called when the genlist is multi-touch pinched
 258  *                     out.
 259  * "multi,pinch,in" - This is called when the genlist is multi-touch pinched in.
