6 * @defgroup Gengrid Gengrid
8 * This widget aims to position objects in a grid layout while
9 * actually building only the visible ones, using the same idea as
10 * genlist: the user define a class for each item, specifying
11 * functions that will be called at object creation and deletion.
13 * Signals that you can add callbacks for are:
15 * clicked - The user has double-clicked a item. The event_info
16 * parameter is the Gengrid item that was double-clicked.
18 * selected - The user has made an item selected. The event_info
19 * parameter is the Gengrid item that was selected.
21 * unselected - The user has made an item unselected. The event_info
22 * parameter is the Gengrid item that was unselected.
24 * realized - This is called when the item in the Gengrid is created
25 * as a real evas object. event_info is the Gengrid item that was
26 * created. The object may be deleted at any time, so it is up to the
27 * caller to not use the object pointer from
28 * elm_gengrid_item_object_get() in a way where it may point to freed
31 * unrealized - This is called when the real evas object for this item
32 * is deleted. event_info is the Gengrid item that was created.
34 * changed - Called when an item is added, removed, resized or moved
35 * and when gengrid is resized or horizontal property changes.
37 * drag,start,up - Called when the item in the Gengrid has been
38 * dragged (not scrolled) up.
40 * drag,start,down - Called when the item in the Gengrid has been
41 * dragged (not scrolled) down.
43 * drag,start,left - Called when the item in the Gengrid has been
44 * dragged (not scrolled) left.
46 * drag,start,right - Called when the item in the Gengrid has been
47 * dragged (not scrolled) right.
49 * drag,stop - Called when the item in the Gengrid has stopped being
52 * drag - Called when the item in the Gengrid is being dragged.
54 * scroll - called when the content has been scrolled (moved).
56 * scroll,drag,start - called when dragging the content has started.
58 * scroll,drag,stop - called when dragging the content has stopped.
61 * A item in the Gengrid can have 0 or more text labels (they can be
62 * regular text or textblock - that's up to the style to determine), 0
63 * or more icons (which are simply objects swallowed into the Gengrid
64 * item) and 0 or more boolean states that can be used for check,
65 * radio or other indicators by the edje theme style. A item may be
66 * one of several styles (Elementary provides 1 by default -
67 * "default", but this can be extended by system or application custom
68 * themes/overlays/extensions).
70 * In order to implement the ability to add and delete items on the
71 * fly, Gengrid implements a class/callback system where the
72 * application provides a structure with information about that type
73 * of item (Gengrid may contain multiple different items with
74 * different classes, states and styles). Gengrid will call the
75 * functions in this struct (methods) when a item is "realized" (that
76 * is created dynamically while scrolling). All objects will simply be
77 * deleted when no longer needed with evas_object_del(). The
78 * Elm_GenGrid_Item_Class structure contains the following members:
80 * item_style - This is a constant string and simply defines the name
81 * of the item style. It must be specified and the default should be
84 * func.label_get - This function is called when an actual item object
85 * is created. The data parameter is the one passed to
86 * elm_gengrid_item_append() and related item creation functions. The
87 * obj parameter is the Gengrid object and the part parameter is the
88 * string name of the text part in the edje design that is listed as
89 * one of the possible labels that can be set. This function must
90 * return a strdup'()ed string as the caller will free() it when done.
92 * func.icon_get - This function is called when an actual item object
93 * is created. The data parameter is the one passed to
94 * elm_gengrid_item_append() and related item creation functions. The
95 * obj parameter is the Gengrid object and the part parameter is the
96 * string name of the icon part in the edje design that is listed as
97 * one of the possible icons that can be set. This must return NULL
98 * for no object or a valid object. The object will be deleted by
99 * Gengrid on shutdown or when the item is unrealized.
101 * func.state_get - This function is called when an actual item object
102 * is created. The data parameter is the one passed to
103 * elm_gengrid_item_append() and related item creation functions. The
104 * obj parameter is the Gengrid object and the part parameter is the
105 * string name of th state part in the edje design that is listed as
106 * one of the possible states that can be set. Return 0 for false and
107 * 1 for true. Gengrid will emit a signal to the edje object with
108 * "elm,state,XXX,active" "elm" when true (the default is false),
109 * where XXX is the name of the part.
111 * func.del - This is called when elm_gengrid_item_del() is called on
112 * a item or elm_gengrid_clear() is called on the Gengrid. This is
113 * intended for use when actual Gengrid items are deleted, so any
114 * backing data attached to the item (e.g. its data parameter on
115 * creation) can be deleted.
117 * If the application wants multiple items to be able to be selected,
118 * elm_gengrid_multi_select_set() can enable this. If the Gengrid is
119 * single-selection only (the default), then
120 * elm_gengrid_select_item_get() will return the selected item, if
121 * any, or NULL if none is selected. If the Gengrid is multi-select
122 * then elm_gengrid_selected_items_get() will return a list (that is
123 * only valid as long as no items are modified (added, deleted,
124 * selected or unselected).
126 * If a item changes (state of boolean changes, label or icons
127 * change), then use elm_gengrid_item_update() to have Gengrid update
128 * the item with the new state. Gengrid will re-realize the item thus
129 * call the functions in the _Elm_Gengrid_Item_Class for that item.
131 * To programmatically (un)select a item use
132 * elm_gengrid_item_selected_set(). To get its selected state use
133 * elm_gengrid_item_selected_get(). To make a item disabled (unable to
134 * be selected and appear differently) use
135 * elm_gengrid_item_disabled_set() to set this and
136 * elm_gengrid_item_disabled_get() to get the disabled state.
138 * Cells will only call their selection func and callback when first
139 * becoming selected. Any further clicks will do nothing, unless you
140 * enable always select with
141 * elm_gengrid_always_select_mode_set(). This means event if selected,
142 * every click will make the selected callbacks be called.
143 * elm_gengrid_no_select_mode_set() will turn off the ability to
144 * select items entirely and they will neither appear selected nor
145 * call selected callback function.
147 * Remember that you can create new styles and add your own theme
148 * augmentation per application with elm_theme_extension_add(). If you
149 * absolutely must have a specific style that overrides any theme the
150 * user or system sets up you can use elm_theme_overlay_add() to add
155 * * Handle non-homogeneous objects too.
