## Implemented Interfaces

GtkCellView implements AtkImplementorIface, GtkBuildable, GtkCellLayout and GtkOrientable.

## Includes

    #include <gtk/gtk.h>

## Description

A GtkCellView displays a single row of a GtkTreeModel using a GtkCellArea and GtkCellAreaContext. A GtkCellAreaContext can be provided to the GtkCellView at construction time in order to keep the cellview in context of a group of cell views, this ensures that the renderers displayed will be properly aligned with eachother (like the aligned cells in the menus of GtkComboBox).

GtkCellView is GtkOrientable in order to decide in which orientation the underlying GtkCellAreaContext should be allocated. Taking the GtkComboBox menu as an example, cellviews should be oriented horizontally if the menus are listed top-to-bottom and thus all share the same width but may have separate individual heights (left-to-right menus should be allocated vertically since they all share the same height but may have variable widths).

### CSS nodes

GtkCellView has a single CSS node with name cellview.

## Functions

### gtk_cell_view_new ()

    GtkWidget *
    gtk_cell_view_new (void);

Creates a new GtkCellView widget.

#### Returns

A newly created GtkCellView widget.

Since: 2.6

### gtk_cell_view_new_with_context ()

    GtkWidget *
    gtk_cell_view_new_with_context (GtkCellArea *area,
                                    GtkCellAreaContext *context);

Creates a new GtkCellView widget with a specific GtkCellArea to layout cells and a specific GtkCellAreaContext.

Specifying the same context for a handfull of cells lets the underlying area synchronize the geometry for those cells, in this way alignments with cellviews for other rows are possible.

#### Parameters

area | the GtkCellArea to layout cells |
context | the GtkCellAreaContext in which to calculate cell geometry |

#### Returns

A newly created GtkCellView widget.

Since: 2.6

### gtk_cell_view_new_with_text ()

    GtkWidget *
    gtk_cell_view_new_with_text (const gchar *text);

Creates a new GtkCellView widget, adds a GtkCellRendererText to it, and makes it show `text` .

#### Parameters

text | the text to display in the cell view |

#### Returns

A newly created GtkCellView widget.

Since: 2.6

### gtk_cell_view_new_with_markup ()

    GtkWidget *
    gtk_cell_view_new_with_markup (const gchar *markup);

Creates a new GtkCellView widget, adds a GtkCellRendererText to it, and makes it show `markup` . The text can be marked up with the Pango text markup language.

#### Parameters

markup | the text to display in the cell view |

#### Returns

A newly created GtkCellView widget.

Since: 2.6

### gtk_cell_view_new_with_pixbuf ()

    GtkWidget *
    gtk_cell_view_new_with_pixbuf (GdkPixbuf *pixbuf);

Creates a new GtkCellView widget, adds a GtkCellRendererPixbuf to it, and makes it show `pixbuf` .

#### Parameters

pixbuf | the image to display in the cell view |

#### Returns

A newly created GtkCellView widget.

Since: 2.6

### gtk_cell_view_set_model ()

    void
    gtk_cell_view_set_model (GtkCellView *cell_view,
                             GtkTreeModel *model);

Sets the model for `cell_view` . If `cell_view` already has a model set, it will remove it before setting the new model. If `model` is `NULL`, then it will unset the old model.

#### Parameters

cell_view | a GtkCellView |
model | a GtkTreeModel. | [allow-none]

Since: 2.6

### gtk_cell_view_get_model ()

    GtkTreeModel *
    gtk_cell_view_get_model (GtkCellView *cell_view);

Returns the model for `cell_view` . If no model is used `NULL` is returned.

#### Parameters

cell_view | a GtkCellView |

#### Returns

a GtkTreeModel used or `NULL`.

[nullable][transfer none]

Since: 2.16

### gtk_cell_view_set_displayed_row ()

    void
    gtk_cell_view_set_displayed_row (GtkCellView *cell_view,
                                     GtkTreePath *path);

Sets the row of the model that is currently displayed by the GtkCellView. If the path is unset, then the contents of the cellview “stick” at their last value; this is not normally a desired result, but may be a needed intermediate state if say, the model for the GtkCellView becomes temporarily empty.

#### Parameters

cell_view | a GtkCellView |
path | a GtkTreePath or `NULL` to unset. | [allow-none]

Since: 2.6

### gtk_cell_view_get_displayed_row ()

    GtkTreePath *
    gtk_cell_view_get_displayed_row (GtkCellView *cell_view);

Returns a GtkTreePath referring to the currently displayed row. If no row is currently displayed, `NULL` is returned.

#### Parameters

cell_view | a GtkCellView |

#### Returns

the currently displayed row or `NULL`.

[nullable][transfer full]

Since: 2.6

### gtk_cell_view_get_size_of_row ()

    gboolean
    gtk_cell_view_get_size_of_row (GtkCellView *cell_view,
                                   GtkTreePath *path,
                                   GtkRequisition *requisition);

`gtk_cell_view_get_size_of_row` has been deprecated since version 3.0 and should not be used in newly-written code.

Combo box formerly used this to calculate the sizes for cellviews, now you can achieve this by either using the “fit-model” property or by setting the currently displayed row of the GtkCellView and using `gtk_widget_get_preferred_size()`.

Sets `requisition` to the size needed by `cell_view` to display the model row pointed to by `path` .

#### Parameters

cell_view | a GtkCellView |
path | a GtkTreePath |
requisition | return location for the size. | [out]

#### Returns

`TRUE`

Since: 2.6

                                        const GdkColor *color);

`gtk_cell_view_set_background_color` has been deprecated since version 3.4 and should not be used in newly-written code.

Use `gtk_cell_view_set_background_rgba()` instead.

                                      gboolean draw_sensitive);

                                 gboolean fit_model);

      “background-set”           gboolean

Whether this tag affects the background color.

Owner: GtkCellView

Flags: Read / Write

Default value: FALSE

### The `“cell-area”` property

      “cell-area”                GtkCellArea *

The GtkCellArea rendering cells

If no area is specified when creating the cell view with `gtk_cell_view_new_with_context()` a horizontally oriented GtkCellAreaBox will be used.

A group of cell views can be assigned the same context in order to ensure the sizes and cell alignments match across all the views with the same context.

GtkComboBox menus uses this to assign the same context to all cell views in the menu items for a single menu (each submenu creates its own context since the size of each submenu does not depend on parent or sibling menus).

since 3.0

Owner: GtkCellView

Flags: Read / Write

Default value: FALSE

### The `“fit-model”` property

      “fit-model”                gboolean

since 3.0

Owner: GtkCellView

Flags: Read / Write

Default value: FALSE

### The `“model”` property

      “model”                    GtkTreeModel *

The model for cell view
