  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  * Signals that you can add callbacks for are:
  19  *
  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.
  22  *
  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.
  25  *
  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.
  28  *
  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.
  33  *
  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.
  38  *
  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.
  44  *
  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.
  50  *
  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.
  56  *
  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.
  60  *
  61  * drag,start,up - This is called when the item in the list has been dragged
  62  * (not scrolled) up.
  63  *
  64  * drag,start,down - This is called when the item in the list has been dragged
  65  * (not scrolled) down.
  66  *
  67  * drag,start,left - This is called when the item in the list has been dragged
  68  * (not scrolled) left.
  69  *
  70  * drag,start,right - This is called when the item in the list has been dragged
  71  * (not scrolled) right.
  72  *
  73  * drag,stop - This is called when the item in the list has stopped being
  74  * dragged.
  75  *
  76  * drag - This is called when the item in the list is being dragged.
  77  *
  78  * longpressed - This is called when the item is pressed for a certain amount
  79  * of time. By default it's 1 second.
  80  *
  81  * scroll,edge,top - This is called when the genlist is scrolled until the top
  82  * edge.
  83  *
  84  * scroll,edge,bottom - This is called when the genlist is scrolled until the
  85  * bottom edge.
  86  *
  87  * scroll,edge,left - This is called when the genlist is scrolled until the
  88  * left edge.
  89  *
  90  * scroll,edge,right - This is called when the genlist is scrolled until the
  91  * right edge.
  92  *
  93  * multi,swipe,left - This is called when the genlist is multi-touch swiped
  94  * left.
  95  *
  96  * multi,swipe,right - This is called when the genlist is multi-touch swiped
  97  * right.
  98  *
  99  * multi,swipe,up - This is called when the genlist is multi-touch swiped
 100  * up.
 101  *
 102  * multi,swipe,down - This is called when the genlist is multi-touch swiped
 103  * down.
 104  *
 105  * multi,pinch,out - This is called when the genlist is multi-touch pinched
 106  * out.
 107  *
 108  * multi,pinch,in - This is called when the genlist is multi-touch pinched
 109  * in.
 110  *
 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.
 114  *
 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.
 136  *
 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
 141  * details.
 142  *
 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 - ?\9cdefault?? ?\9cdouble_label?? "group_index"
 149  * and "icon_top_text_bottom", but this can be extended by system or
 150  * application custom themes/overlays/extensions).
 151  *
 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  * ?\9crealized??(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:
 160  *
 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 ?\9cdefault??
 163  *
 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.
 171  *
 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
 179  * is unrealized.
 180  *
 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 ?\9celm,state,XXX,active???\9celm??when
 188  * true (the default is false), where XXX is the name of the part.
 189  *
 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
 195  * deleted.
 196  *
 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.
 211  *
 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.
 218  *
 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.
 223  *
 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)).
 231  *
 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
 240  * wanted).
 241  *
 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.
 247  *
 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.
 252  *
 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.
 260  *
 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
 269  * this: ?\9ctex...??.
 270  *
 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.
 278  *
 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.
