/**

* @defgroup Genlist Genlist
|
||
*
|
||
* The Aim was to have more expansive list that the simple list in
|
||
* Elementary that could have more flexible items and allow many more entries
|
||
* while still being fast and low on memory usage. At the same time it was
|
||
* also made to be able to do tree structures. But the price to pay is more
|
||
* complexity when it comes to usage. If all you want is a simple list with
|
||
* icons and a single label, use the normal List object.
|
||
*
|
||
* Signals that you can add callbacks for are:
|
||
*
|
||
* clicked - This is called when a user has double-clicked an item. The
|
||
* event_info parameter is the genlist item that was double-clicked.
|
||
*
|
||
* selected - This is called when a user has made an item selected. The
|
||
* event_info parameter is the genlist item that was selected.
|
||
*
|
||
* unselected - This is called when a user has made an item unselected. The
|
||
* event_info parameter is the genlist item that was unselected.
|
||
*
|
||
* expanded - This is called when elm_genlist_item_expanded_set() is called
|
||
* and the item is now meant to be expanded. The event_info parameter is the
|
||
* genlist item that was indicated to expand. It is the job of this callback
|
||
* to then fill in the child items.
|
||
*
|
||
* contracted - This is called when elm_genlist_item_expanded_set() is called
|
||
* and the item is now meant to be contracted. The event_info parameter is
|
||
* the genlist item that was indicated to contract. It is the job of this
|
||
* callback to then delete the child items
|
||
*
|
||
* expand,request - This is called when a user has indicated they want to
|
||
* expand a tree branch item. The callback should decide if the item can
|
||
* expand (has any children) and then call elm_genlist_item_expanded_set()
|
||
* appropriately to set the state. The event_info parameter is the genlist
|
||
* item that was indicated to expand.
|
||
*
|
||
* contract,request - This is called when a user has indicated they want to
|
||
* contract a tree branch item. The callback should decide if the item can
|
||
* contract (has any children) and then call elm_genlist_item_expanded_set()
|
||
* appropriately to set the state. The event_info parameter is the genlist
|
||
* item that was indicated to contract.
|
||
*
|
||
* realized - This is called when the item in the list is created as a real
|
||
* evas object. event_info parameter is the genlist item that was created.
|
||
* The object may be deleted at any time, so it is up to the caller to
|
||
* not use the object pointer from elm_genlist_item_object_get() in a way
|
||
* where it may point to freed objects.
|
||
*
|
||
* unrealized - This is called just before an item is unrealized. After
|
||
* this call icon objects provideed will be deleted and the item object
|
||
* itself delete or be put into a floating cache.
|
||
*
|
||
* drag,start,up - This is called when the item in the list has been dragged
|
||
* (not scrolled) up.
|
||
*
|
||
* drag,start,down - This is called when the item in the list has been dragged
|
||
* (not scrolled) down.
|
||
*
|
||
* drag,start,left - This is called when the item in the list has been dragged
|
||
* (not scrolled) left.
|
||
*
|
||
* drag,start,right - This is called when the item in the list has been dragged
|
||
* (not scrolled) right.
|
||
*
|
||
* drag,stop - This is called when the item in the list has stopped being
|
||
* dragged.
|
||
*
|
||
* drag - This is called when the item in the list is being dragged.
|
||
*
|
||
* longpressed - This is called when the item is pressed for a certain amount
|
||
* of time. By default it's 1 second.
|
||
*
|
||
* scroll,edge,top - This is called when the genlist is scrolled until the top
|
||
* edge.
|
||
*
|
||
* scroll,edge,bottom - This is called when the genlist is scrolled until the
|
||
* bottom edge.
|
||
*
|
||
* scroll,edge,left - This is called when the genlist is scrolled until the
|
||
* left edge.
|
||
*
|
||
* scroll,edge,right - This is called when the genlist is scrolled until the
|
||
* right edge.
|
||
*
|
||
* Genlist has a fairly large API, mostly because it's relatively complex,
|
||
* trying to be both expansive, powerful and efficient. First we will begin
|
||
* an overview o the theory behind genlist.
|
||
*
|
||
* Evas tracks every object you create. Every time it processes an event
|
||
* (mouse move, down, up etc.) it needs to walk through objects and find out
|
||
* what event that affects. Even worse every time it renders display updates,
|
||
* in order to just calculate what to re-draw, it needs to walk through many
|
||
* many many objects. Thus, the more objects you keep active, the more
|
||
* overhead Evas has in just doing its work. It is advisable to keep your
|
||
* active objects to the minimum working set you need. Also remember that
|
||
* object creation and deletion carries an overhead, so there is a
|
||
* middle-ground, which is not easily determined. But don't keep massive lists
|
||
* of objects you can't see or use. Genlist does this with list objects. It
|
||
* creates and destroys them dynamically as you scroll around. It groups them
|
||
* into blocks so it can determine the visibility etc. of a whole block at
|
||
* once as opposed to having to walk the whole list. This 2-level list allows
|
||
* for very large numbers of items to be in the list (tests have used up to
|
||
* 2,000,000 items). Also genlist employs a queue for adding items. As items
|
||
* may be different sizes, every item added needs to be calculated as to its
|
||
* size and thus this presents a lot of overhead on populating the list, this
|
||
* genlist employs a queue. Any item added is queued and spooled off over
|
||
* time, actually appearing some time later, so if your list has many members
|
||
* you may find it takes a while for them to all appear, with your process
|
||
* consuming a lot of CPU while it is busy spooling.
|
||
*
|
||
* Genlist also implements a tree structure, but it does so with callbacks to
|
||
* the application, with the application filling in tree structures when
|
||
* requested (allowing for efficient building of a very deep tree that could
|
||
* even be used for file-management). See the above smart signal callbacks for
|
||
* details.
|
||
*
|
||
* An item in the genlist world can have 0 or more text labels (they can be
|
||
* regular text or textblock – that's up to the style to determine), 0 or
|
||
* more icons (which are simply objects swallowed into the genlist item) and
|
||
* 0 or more boolean states that can be used for check, radio or other
|
||
* indicators by the edje theme style. An item may be one of several styles
|
||
* (Elementary provides 2 by default - “default” and “double_label”, but this
|
||
* can be extended by system or application custom themes/overlays/extensions).
|
||
*
|
||
* In order to implement the ability to add and delete items on the fly,
|
||
* Genlist implements a class/callback system where the application provides
|
||
* a structure with information about that type of item (genlist may contain
|
||
* multiple different items with different classes, states and styles).
|
||
* Genlist will call the functions in this struct (methods) when an item is
|
||
* “realized” (that is created dynamically while scrolling). All objects will
|
||
* simply be deleted when no longer needed with evas_object_del(). The
|
||
* Elm_Genlist_Item_Class structure contains the following members:
|
||
*
|
||
* item_style - This is a constant string and simply defines the name of the
|
||
* item style. It must be specified and the default should be “default”.
|
||
*
|
||
* func.label_get - This function is called when an actual item object is
|
||
* created. The data parameter is the data parameter passed to
|
||
* elm_genlist_item_append() and related item creation functions. The obj
|
||
* parameter is the genlist object and the part parameter is the string name
|
||
* of the text part in the edje design that is listed as one of the possible
|
||
* labels that can be set. This function must return a strudup()'ed string as
|
||
* the caller will free() it when done.
|
||
*
|
||
* func.icon_get - This function is called when an actual item object is
|
||
* created. The data parameter is the data parameter passed to
|
||
* elm_genlist_item_append() and related item creation functions. The obj
|
||
* parameter is the genlist object and the part parameter is the string name
|
||
* of the icon part in the edje design that is listed as one of the possible
|
||
* icons that can be set. This must return NULL for no object or a valid
|
||
* object. The object will be deleted by genlist on shutdown or when the item
|
||
* its unrealized.
|
||
*
|
||
* func.state_get - This function is called when an actual item object is
|
||
* created. The data parameter is the data parameter passed to
|
||
* elm_genlist_item_append() and related item creation functions. The obj
|
||
* parameter is the genlist object and the part parameter is the string name
|
||
* of the state part in the edje design that is listed as one of the possible
|
||
* states that can be set. Return 0 for false or 1 for true. Genlist will
|
||
* emit a signal to the edje object with “elm,state,XXX,active” “elm” when
|
||
* true (the default is false), where XXX is the name of the part.
|
||
*
|
||
* func.del - This is called when elm_genlist_item_del() is called on an
|
||
* item, elm_genlist_clear() is called on the genlist, or
|
||
* elm_genlist_item_subitems_clear() is called to clear sub-items. This is
|
||
* intended for use when actual genlist items are deleted, so any backing
|
||
* data attached to the item (e.g. its data parameter on creation) can be
|
||
* deleted.
|
||
*
|
||
* Items can be added by several calls. All of them return a Elm_Genlist_Item
|
||
* handle that is an internal member inside the genlist. They all take a data
|
||
* parameter that is meant to be used for a handle to the applications
|
||
* internal data (eg the struct with the original item data). The parent
|
||
* parameter is the parent genlist item this belongs to if it is a tree, and
|
||
* NULL if there is no parent. The flags can be a bitmask of
|
||
* ELM_GENLIST_ITEM_NONE and ELM_GENLIST_ITEM_SUBITEMS. If
|
||
* ELM_GENLIST_ITEM_SUBITEMS is set then this item is displayed as a item
|
||
* that is able to expand and have child items. The func parameter is a
|
||
* convenience callback that is called when the item is selected and the data
|
||
* parameter will be the func_data parameter, obj be the genlist object and
|
||
* vent_info will be the genlist item.
|
||
*
|
||
* elm_genlist_item_append() appends an item to the end of the list, or if
|
||
* there is a parent, to the end of all the child items of the parent.
|
||
* elm_genlist_item_prepend() is the same but prepends to the beginning of
|
||
* the list or children list. elm_genlist_item_insert_before() inserts at
|
||
* item before another item and elm_genlist_item_insert_after() inserts after
|
||
* the indicated item.
|
||
*
|
||
* The application can clear the list with elm_genlist_clear() which deletes
|
||
* all the items in the list and elm_genlist_item_del() will delete a specific
|
||
* item. elm_genlist_item_subitems_clear() will clear all items that are
|
||
* children of the indicated parent item.
|
||
*
|
||
* If the application wants multiple items to be able to be selected,
|
||
* elm_genlist_multi_select_set() can enable this. If the list is
|
||
* single-selection only (the default), then elm_genlist_selected_item_get()
|
||
* will return the selected item, if any, or NULL I none is selected. If the
|
||
* list is multi-select then elm_genlist_selected_items_get() will return a
|
||
* list (that is only valid as long as no items are modified (added, deleted,
|
||
* selected or unselected).
|
||
*
|
||
* To help inspect list items you can jump to the item at the top of the list
|
||
* with elm_genlist_first_item_get() which will return the item pointer, and
|
||
* similarly elm_genlist_last_item_get() gets the item at the end of the list.
|
||
* elm_genlist_item_next_get() and elm_genlist_item_prev_get() get the next
|
||
* and previous items respectively relative to the indicated item. Using
|
||
* these calls you can walk the entire item list/tree. Note that as a tree
|
||
* the items are flattened in the list, so elm_genlist_item_parent_get() will
|
||
* let you know which item is the parent (and thus know how to skip them if
|
||
* wanted).
|
||
*
|
||
* There are also convenience functions. elm_genlist_item_genlist_get() will
|
||
* return the genlist object the item belongs to. elm_genlist_item_show()
|
||
* will make the scroller scroll to show that specific item so its visible.
|
||
* elm_genlist_item_data_get() returns the data pointer set by the item
|
||
* creation functions.
|
||
*
|
||
* If an item changes (state of boolean changes, label or icons change),
|
||
* then use elm_genlist_item_update() to have genlist update the item with
|
||
* the new state. Genlist will re-realize the item thus call the functions
|
||
* in the _Elm_Genlist_Item_Class for that item.
|
||
*
|
||
* To programmatically (un)select an item use elm_genlist_item_selected_set().
|
||
* To get its selected state use elm_genlist_item_selected_get(). Similarly
|
||
* to expand/contract and item and get its expanded state, use
|
||
* elm_genlist_item_expanded_set() and elm_genlist_item_expanded_get(). And
|
||
* again to make an item disabled (unable to be selected and appear
|
||
* differently) use elm_genlist_item_disabled_set() to set this and
|
||
* elm_genlist_item_disabled_get() to get the disabled state.
|
||
*
|
||
* In general to indicate how the genlist should expand items horizontally to
|
||
* fill the list area, use elm_genlist_horizontal_mode_set(). Valid modes are
|
||
* ELM_LIST_LIMIT and ELM_LIST_SCROLL . The default is ELM_LIST_SCROLL. This
|
||
* mode means that if items are too wide to fit, the scroller will scroll
|
||
* horizontally. Otherwise items are expanded to fill the width of the
|
||
* viewport of the scroller. If it is ELM_LIST_LIMIT, Items will be expanded
|
||
* to the viewport width and limited to that size. This can be combined with
|
||
* a different style that uses edjes' ellipsis feature (cutting text off like
|
||
* this: “tex...”).
|
||
*
|
||
* Items will only call their selection func and callback when first becoming
|
||
* selected. Any further clicks will do nothing, unless you enable always
|
||
* select with elm_genlist_always_select_mode_set(). This means even if
|
||
* selected, every click will make the selected callbacks be called.
|
||
* elm_genlist_no_select_mode_set() will turn off the ability to select
|
||
* items entirely and they will neither appear selected nor call selected
|
||
* callback functions.
|
||
*
|
||
* Remember that you can create new styles and add you own theme augmentation
|
||
* per application with elm_theme_extension_add(). If you absolutely must
|
||
* have a specific style that overrides any theme the user or system sets up
|
||
* you can use elm_theme_overlay_add() to add such a file.
