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 * A item in the Gengrid can have 0 or more text labels (they can be
14 * regular text or textblock - that's up to the style to determine), 0
15 * or more icons (which are simply objects swallowed into the Gengrid
16 * item) and 0 or more boolean states that can be used for check,
17 * radio or other indicators by the edje theme style. A item may be
18 * one of several styles (Elementary provides 1 by default -
19 * "default", but this can be extended by system or application custom
20 * themes/overlays/extensions).
22 * In order to implement the ability to add and delete items on the
23 * fly, Gengrid implements a class/callback system where the
24 * application provides a structure with information about that type
25 * of item (Gengrid may contain multiple different items with
26 * different classes, states and styles). Gengrid will call the
27 * functions in this struct (methods) when an item is "realized" (that
28 * is created dynamically while scrolling). All objects will simply be
29 * deleted when no longer needed with evas_object_del(). The
30 * Elm_GenGrid_Item_Class structure contains the following members:
32 * item_style - This is a constant string and simply defines the name
33 * of the item style. It must be specified and the default should be
36 * func.label_get - This function is called when an actual item object
37 * is created. The data parameter is the one passed to
38 * elm_gengrid_item_append() and related item creation functions. The
39 * obj parameter is the Gengrid object and the part parameter is the
40 * string name of the text part in the edje design that is listed as
41 * one of the possible labels that can be set. This function must
42 * return a strdup'()ed string as the caller will free() it when done.
44 * func.icon_get - This function is called when an actual item object
45 * is created. The data parameter is the one passed to
46 * elm_gengrid_item_append() and related item creation functions. The
47 * obj parameter is the Gengrid object and the part parameter is the
48 * string name of the icon part in the edje design that is listed as
49 * one of the possible icons that can be set. This must return NULL
50 * for no object or a valid object. The object will be deleted by
51 * Gengrid on shutdown or when the item is unrealized.
53 * func.state_get - This function is called when an actual item object
54 * is created. The data parameter is the one passed to
55 * elm_gengrid_item_append() and related item creation functions. The
56 * obj parameter is the Gengrid object and the part parameter is the
57 * string name of th state part in the edje design that is listed as
58 * one of the possible states that can be set. Return 0 for false and
59 * 1 for true. Gengrid will emit a signal to the edje object with
60 * "elm,state,XXX,active" "elm" when true (the default is false),
61 * where XXX is the name of the part.
63 * func.del - This is called when elm_gengrid_item_del() is called on
64 * an item or elm_gengrid_clear() is called on the Gengrid. This is
65 * intended for use when actual Gengrid items are deleted, so any
66 * backing data attached to the item (e.g. its data parameter on
67 * creation) can be deleted.
69 * If the application wants multiple items to be able to be selected,
70 * elm_gengrid_multi_select_set() can enable this. If the Gengrid is
71 * single-selection only (the default), then
72 * elm_gengrid_select_item_get() will return the selected item, if
73 * any, or NULL if none is selected. If the Gengrid is multi-select
74 * then elm_gengrid_selected_items_get() will return a list (that is
75 * only valid as long as no items are modified (added, deleted,
76 * selected or unselected).
78 * If an item changes (state of boolean changes, label or icons
79 * change), then use elm_gengrid_item_update() to have Gengrid update
80 * the item with the new state. Gengrid will re-realize the item thus
81 * call the functions in the _Elm_Gengrid_Item_Class for that item.
83 * To programmatically (un)select an item use
84 * elm_gengrid_item_selected_set(). To get its selected state use
85 * elm_gengrid_item_selected_get(). To make an item disabled (unable to
86 * be selected and appear differently) use
87 * elm_gengrid_item_disabled_set() to set this and
88 * elm_gengrid_item_disabled_get() to get the disabled state.
90 * Cells will only call their selection func and callback when first
91 * becoming selected. Any further clicks will do nothing, unless you
92 * enable always select with
93 * elm_gengrid_always_select_mode_set(). This means event if selected,
94 * every click will make the selected callbacks be called.
95 * elm_gengrid_no_select_mode_set() will turn off the ability to
96 * select items entirely and they will neither appear selected nor
97 * call selected callback function.
99 * Remember that you can create new styles and add your own theme
100 * augmentation per application with elm_theme_extension_add(). If you
101 * absolutely must have a specific style that overrides any theme the
102 * user or system sets up you can use elm_theme_overlay_add() to add
105 * Signals that you can add callbacks for are:
107 * "clicked,double" - The user has double-clicked or pressed enter on
108 * an item. The event_infoparameter is the Gengrid item
109 * that was double-clicked.
110 * "selected" - The user has made an item selected. The event_info
111 * parameter is the Gengrid item that was selected.
112 * "unselected" - The user has made an item unselected. The event_info
113 * parameter is the Gengrid item that was unselected.
114 * "realized" - This is called when the item in the Gengrid is created
115 * as a real evas object. event_info is the Gengrid item that was
116 * created. The object may be deleted at any time, so it is up to
117 * the caller to not use the object pointer from
118 * elm_gengrid_item_object_get() in a way where it may point to
120 * "unrealized" - This is called when the real evas object for this item
121 * is deleted. event_info is the Gengrid item that was created.
122 * "changed" - Called when an item is added, removed, resized or moved
123 * and when gengrid is resized or horizontal property changes.
124 * "drag,start,up" - Called when the item in the Gengrid has been
125 * dragged (not scrolled) up.
126 * "drag,start,down" - Called when the item in the Gengrid has been
127 * dragged (not scrolled) down.
128 * "drag,start,left" - Called when the item in the Gengrid has been
129 * dragged (not scrolled) left.
130 * "drag,start,right" - Called when the item in the Gengrid has been
131 * dragged (not scrolled) right.
132 * "drag,stop" - Called when the item in the Gengrid has stopped being
134 * "drag" - Called when the item in the Gengrid is being dragged.
135 * "scroll" - called when the content has been scrolled (moved).
136 * "scroll,drag,start" - called when dragging the content has started.
137 * "scroll,drag,stop" - called when dragging the content has stopped.
141 * Handle non-homogeneous objects too.
