## Detailed Description

This widget aims to position objects in a grid layout while actually creating and rendering only the visible ones, using the same idea as the genlist: the user defines a class for each item, specifying functions that will be called at object creation, deletion, etc. When those items are selected by the user, a callback function is issued. Users may interact with a gengrid via the mouse (by clicking on items to select them and clicking on the grid's viewport and swiping to pan the whole view) or via the keyboard, navigating through item with the arrow keys.

This widget inherits from the Layout one, so that all the functions acting on it also work for gengrid objects.

This widget implements the elm-scrollable-interface interface, so that all (non-deprecated) functions for the base Scroller widget also work for gengrids.

Some calls on the gengrid's API are marked as deprecated, as they just wrap the scrollable widgets counterpart functions. Use the ones we point you to, for each case of deprecation here, instead – eventually the deprecated ones will be discarded (next major release).

# Gengrid layouts

Gengrid may layout its items in one of two possible layouts:

- horizontal or
- vertical.

When in "horizontal mode", items will be placed in columns, from top to bottom and, when the space for a column is filled, another one is started on the right, thus expanding the grid horizontally, making for horizontal scrolling. When in "vertical mode" , though, items will be placed in rows, from left to right and, when the space for a row is filled, another one is started below, thus expanding the grid vertically (and making for vertical scrolling).

# Gengrid items

An item in a gengrid can have 0 or more texts (they can be regular text or textblock Evas objects - that's up to the style to determine), 0 or more contents (which are simply objects swallowed into the gengrid item's theming Edje object) and 0 or more boolean states, which have the behavior left to the user to define. The Edje part names for each of these properties will be looked up, in the theme file for the gengrid, under the Edje (string) data items named `"texts"`, `"contents"` and `"states"`, respectively. For each of those properties, if more than one part is provided, they must have names listed separated by spaces in the data fields. For the default gengrid item theme, we have one text part (`"elm.text"`), two content parts (`"elm.swallow.icon"` and `"elm.swallow.end"`) and no state parts.

A gengrid item may be at one of several styles. Elementary provides one by default - "default", but this can be extended by system or application custom themes/overlays/extensions (see themes for more details).

# Gengrid item classes

In order to have the ability to add and delete items on the fly, gengrid implements a class (callback) system where the application provides a structure with information about that type of item (gengrid may contain multiple different items with different classes, states and styles). Gengrid will call the functions in this struct (methods) when an item is "realized" (i.e., created dynamically, while the user is scrolling the grid). All objects will simply be deleted when no longer needed with evas_object_del(). The #Elm_Gengrid_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.text_get` - This function is called when an item object is actually created. The `data` parameter will point to the same data passed to elm_gengrid_item_append() and related item creation functions. The `obj` parameter is the gengrid object itself, while the `part` one is the name string of one of the existing text parts in the Edje group implementing the item's theme. This function must return a strdup'()ed string, as the caller will free() it when done. See #Elm_Gengrid_Item_Text_Get_Cb.
- `func.content_get` - This function is called when an item object is actually created. The `data` parameter will point to the same data passed to elm_gengrid_item_append() and related item creation functions. The `obj` parameter is the gengrid object itself, while the `part` one is the name string of one of the existing (content) swallow parts in the Edje group implementing the item's theme. It must return `NULL`, when no content is desired, or a valid object handle, otherwise. The object will be deleted by the gengrid on its deletion or when the item is "unrealized". See #Elm_Gengrid_Item_Content_Get_Cb.
- `func.state_get` - This function is called when an item object is actually created. The `data` parameter will point to the same data passed to elm_gengrid_item_append() and related item creation functions. The `obj` parameter is the gengrid object itself, while the `part` one is the name string of one of the state parts in the Edje group implementing the item's theme. Return `EINA_FALSE` for false/off or `EINA_TRUE` for true/on. Gengrids will emit a signal to its theming Edje object with `"elm,state,xxx,active"` and `"elm"` as "emission" and "source" arguments, respectively, when the state is true (the default is false), where `xxx` is the name of the (state) part. See #Elm_Gengrid_Item_State_Get_Cb.
- `func.del` - This is called when elm_object_item_del() is called on an item or elm_gengrid_clear() is called on the gengrid. This is intended for use when gengrid items are deleted, so any data attached to the item (e.g. its data parameter on creation) can be deleted. See #Elm_Gengrid_Item_Del_Cb.

# Usage hints

If the user wants to have multiple items selected at the same time, elm_gengrid_multi_select_set() will permit it. If the gengrid is single-selection only (the default), then elm_gengrid_select_item_get() will return the selected item or `NULL`, if none is selected. If the gengrid is under multi-selection, then elm_gengrid_selected_items_get() will return a list (that is only valid as long as no items are modified (added, deleted, selected or unselected) of child items on a gengrid.

If an item changes (internal (boolean) state, text or content changes), then use elm_gengrid_item_update() to have gengrid update the item with the new state. A gengrid will re-"realize" the item, thus calling the functions in the #Elm_Gengrid_Item_Class set for that item.

To programmatically (un)select an item, use elm_gengrid_item_selected_set(). To get its selected state use elm_gengrid_item_selected_get(). To make an item disabled (unable to be selected and appear differently) use elm_object_item_disabled_set() to set this and elm_object_item_disabled_get() to get the disabled state.

Grid cells will only have their selection smart callbacks called when firstly getting selected. Any further clicks will do nothing, unless you enable the "always select mode", with elm_gengrid_select_mode_set() as ELM_OBJECT_SELECT_MODE_ALWAYS, thus making every click to issue selection callbacks. elm_gengrid_select_mode_set() as ELM_OBJECT_SELECT_MODE_NONE will turn off the ability to select items entirely in the widget and they will neither appear selected nor call the selection smart callbacks.

Remember that you can create new styles and add your 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.

# Gengrid smart events

This widget emits the following signals, besides the ones sent from Layout:

- `"activated"` - The user has double-clicked or pressed (enter|return|spacebar) on an item. The `event_info` parameter is the gengrid item that was activated.
- `"pressed"` - The user pressed the an item. The `event_info` parameter is the item that was pressed.
- `"released"` - The user released the an item. The `event_info` parameter is the item that was released.
- `"clicked,double"` - The user has double-clicked an item. The `event_info` parameter is the gengrid item that was double-clicked.
- `"clicked,right"` - The user has right-clicked an item. The `event_info` parameter is the item that was right-clicked. (since 1.13)
- `"longpressed"` - This is called when the item is pressed for a certain amount of time. By default it's 1 second.
- `"selected"` - The user has made an item selected. The `event_info` parameter is the gengrid item that was selected.
- `"unselected"` - The user has made an item unselected. The `event_info` parameter is the gengrid item that was unselected.
- `"realized"` - This is called when the item in the gengrid has its implementing Evas object instantiated, de facto. `event_info` is the gengrid item that was created.
- `"unrealized"` - This is called when the implementing Evas object for this item is deleted. `event_info` is the gengrid item that was deleted.
- `"changed"` - Called when an item is added, removed, resized or moved and when the gengrid is resized or gets "horizontal" property changes.

## ◆ elm_gengrid_align_get()

void elm_gengrid_align_get | ( | const Elm_Gengrid * | obj,
|  | double * | align_x,
|  | double * | align_y
| ) |  |

Get the items grid's alignment values within a given gengrid widget.

Note
  Use `null` pointers on the alignment values you're not interested in: they'll be ignored by the function.

Parameters

  [out] | align_x | Alignment in the horizontal axis (0 <= align_x <= 1).
  [out] | align_y | Alignment in the vertical axis (0 <= align_y <= 1).

References elm_obj_gengrid_align_get().

## ◆ elm_gengrid_align_set()

void elm_gengrid_align_set | ( | Elm_Gengrid * | obj,
|  | double | align_x,
|  | double | align_y
| ) |  |

Set the items grid's alignment within a given gengrid widget.

This sets the alignment of the whole grid of items of a gengrid within its given viewport. By default, those values are both 0.5, meaning that the gengrid will have its items grid placed exactly in the middle of its viewport.

Note
  If given alignment values are out of the cited ranges, they'll be changed to the nearest boundary values on the valid ranges.

Parameters

  [in] | align_x | Alignment in the horizontal axis (0 <= align_x <= 1).
  [in] | align_y | Alignment in the vertical axis (0 <= align_y <= 1).

|  | Evas_Coord | y,
|  | int * | xposret,
|  | int * | yposret
| ) |  |

Get the item that is at the x, y canvas coords.

This returns the item at the given coordinates (which are canvas relative, not object-relative). If an item is at that coordinate, that item handle is returned, and if `xposret` is not `null`, the integer pointed to is set to a value of -1, 0 or 1, depending if the coordinate is on the left portion of that item (-1), on the middle section (0) or on the right part (1).

If `yposret` is not `null`, the integer pointed to is set to a value of -1, 0 or 1, depending if the coordinate is on the upper portion of that item (-1), on the middle section (0) or on the lower part (1). If NULL is returned as an item (no item found there), then posret may indicate -1 or 1 based if the coordinate is above or below all items respectively in the gengrid.

Parameters

  [in] | y | The input y coordinate.
  [out] | xposret | The position relative to the item returned here.
  [out] | yposret | The position relative to the item returned here.

Returns
  The item at the coordinates or `null` if none.

Parameters

  it | item with custom (custom) cursor already set on
  engine_only | Use `EINA_TRUE` to have cursors looked for only on those provided by the rendering engine, `EINA_FALSE` to have them searched on the widget's theme, as well.

Note
  This call is of use only if you've set a custom cursor for gengrid items, with elm_gengrid_item_cursor_set().
  By default, cursors will only be looked for between those provided by the rendering engine.

## ◆ elm_gengrid_item_cursor_get()

const char* elm_gengrid_item_cursor_get | ( | const Elm_Object_Item * | it | ) |

Get the type of mouse pointer/cursor decoration set to be shown, when the mouse pointer is over the given gengrid widget item.

Parameters

  it | gengrid item with custom cursor set

Returns
  the cursor type's name or `NULL`, if no custom cursors were set to `item` (and on errors)

| ) |  |

Set the type of mouse pointer/cursor decoration to be shown, when the mouse pointer is over the given gengrid widget item.

Parameters

  it | gengrid item to customize cursor on
  cursor | the cursor type's name

This function works analogously as elm_object_cursor_set(), but here the cursor's changing area is restricted to the item's area, and not the whole widget's. Note that that item cursors have precedence over widget cursors, so that a mouse over `item` will always show cursor `type`.

If this function is called twice for an object, a previously set cursor will be unset on the second call.

  style | the theme style to use (e.g. `"default"`, `"transparent"`, etc)

This function only makes sense when one is using custom mouse cursor decorations defined in a theme file , which can have, given a cursor name/type, alternate styles on it. It works analogously as elm_object_cursor_style_set(), but here applied only to gengrid item objects.

Warning
  Before you set a cursor style you should have defined a custom cursor previously on the item, with elm_gengrid_item_cursor_set()

Parameters

  it | The gengrid item object
  mode | The select mode

elm_gengrid_select_mode_set() changes item's select mode.

- ELM_OBJECT_SELECT_MODE_DEFAULT : The item will only call their selection func and callback when first becoming selected. Any further clicks will do nothing, unless you set always select mode.
- ELM_OBJECT_SELECT_MODE_ALWAYS : This means that, even if selected, every click will make the selected callbacks be called.
- ELM_OBJECT_SELECT_MODE_NONE : This will turn off the ability to select the item entirely and they will neither appear selected nor call selected callback functions.
- ELM_OBJECT_SELECT_MODE_DISPLAY_ONLY : This will apply no-finger-size rule with ELM_OBJECT_SELECT_MODE_NONE. No-finger-size rule makes an item can be smaller than lower limit. Clickable objects should be bigger than human touch point device (your finger) for some touch or small screen devices. So it is enabled, the item can be shrink than predefined finger-size value. And the item will be updated.

void elm_gengrid_item_tooltip_content_cb_set | ( | Elm_Object_Item * | it,
|  | Elm_Tooltip_Item_Content_Cb | func,
|  | const void * | data,
|  | Evas_Smart_Cb | del_cb
| ) |  |

Set the content to be shown in a given gengrid item's tooltip.

Parameters

  it | The gengrid item.
  func | The function returning the tooltip contents.
  data | What to provide to func as callback data/context.
  del_cb | Called when data is not needed anymore, either when another callback replaces `func`, the tooltip is unset with elm_gengrid_item_tooltip_unset() or the owner `item` dies. This callback receives as its first parameter the given `data`, being `event_info` the item handle.

This call will setup the tooltip's contents to `item` (analogous to elm_object_tooltip_content_cb_set(), but being item tooltips with higher precedence than object tooltips). It can have only one tooltip at a time, so any previous tooltip content will get removed. `func` (with `data`) will be called every time Elementary needs to show the tooltip and it should return a valid Evas object, which will be fully managed by the tooltip system, getting deleted when the tooltip is gone.

In order to set just a text as a tooltip, look at elm_gengrid_item_tooltip_text_set().

## ◆ elm_gengrid_item_tooltip_style_get()

const char* elm_gengrid_item_tooltip_style_get | ( | const Elm_Object_Item * | it | ) |

Get the style set a given gengrid item's tooltip.

Parameters

  it | gengrid item with tooltip already set on.

Returns
  style the theme style in use, which defaults to "default". If the object does not have a tooltip set, then `NULL` is returned.

## ◆ elm_gengrid_item_tooltip_style_set()

void elm_gengrid_item_tooltip_style_set | ( | Elm_Object_Item * | it,
|  | const char * | style
| ) |  |

Set a different style for a given gengrid item's tooltip.

Parameters

  it | gengrid item with tooltip set
  style | the theme style to use on tooltips (e.g. `"default"`, `"transparent"`, etc)

Tooltips can have alternate styles to be displayed on, which are defined by the theme set on Elementary. This function works analogously as elm_object_tooltip_style_set(), but here applied only to gengrid item objects. The default style for tooltips is `"default"`.

Note
  before you set a style you should define a tooltip with elm_gengrid_item_tooltip_content_cb_set() or elm_gengrid_item_tooltip_text_set()

Parameters

  it | The gengrid item
  text | The text to set in the content

This call will setup the text to be used as tooltip to that item (analogous to elm_object_tooltip_text_set(), but being item tooltips with higher precedence than object tooltips). It can have only one tooltip at a time, so any previous tooltip data will get removed.

In order to set a content or something else as a tooltip, look at elm_gengrid_item_tooltip_content_cb_set().

This returns the item at the given coordinates (which are canvas relative, not object-relative). If an item is at that coordinate, that item handle is returned, and if `xposret` is not `null`, the integer pointed to is set to a value of -1, 0 or 1, depending if the coordinate is on the left portion of that item (-1), on the middle section (0) or on the right part (1).

If `yposret` is not `null`, the integer pointed to is set to a value of -1, 0 or 1, depending if the coordinate is on the upper portion of that item (-1), on the middle section (0) or on the lower part (1). If NULL is returned as an item (no item found there), then posret may indicate -1 or 1 based if the coordinate is above or below all items respectively in the gengrid.

Parameters

  [in] | y | The input y coordinate.
  [out] | xposret | The position relative to the item returned here.

EOAPI void elm_obj_gengrid_item_size_set | ( | Evas_Coord | w,
|  | Evas_Coord | h
| ) |  |

Set the size for the items of a given gengrid widget.

A gengrid, after creation, has still no information on the size to give to each of its cells. So, you most probably will end up with squares one finger wide, the default size. Use this function to force a custom size for you items, making them as big as you wish.

Parameters

  [in] | w | The items' width.
  [in] | h | The items' height.

## ◆ elm_obj_gengrid_multi_select_set()

EOAPI void elm_obj_gengrid_multi_select_set | ( | Eina_Bool | multi | ) |

Enable or disable multi-selection in a given gengrid widget.

Multi-selection is the ability to have more than one item selected, on a given gengrid, simultaneously. When it is enabled, a sequence of clicks on different items will make them all selected, progressively. A click on an already selected item will unselect it. If interacting via the keyboard, multi-selection is enabled while holding the "Shift" key.

Note
  By default, multi-selection is disabled on gengrids.

## ◆ elm_obj_gengrid_reorder_mode_set()

EOAPI void elm_obj_gengrid_reorder_mode_set | ( | Eina_Bool | reorder_mode | ) |

Set whether a given gengrid widget is or not able have items reordered.

If a gengrid is set to allow reordering, a click held for more than 0.5 over a given item will highlight it specially, signaling the gengrid has entered the reordering state. From that time on, the user will be able to, while still holding the mouse button down, move the item freely in the gengrid's viewport, replacing to said item to the locations it goes to. The replacements will be animated and, whenever the user releases the mouse button, the item being replaced gets a new definitive place in the grid.

Parameters
