## 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).

### struct GtkCellView

    struct GtkCellView;

### 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.

`area` : | the GtkCellArea to layout cells
`context` : | the GtkCellAreaContext in which to calculate cell geometry
Returns : | A newly created GtkCellView widget.

Since 2.6

    GtkWidget *         gtk_cell_view_new_with_text         (const gchar *text);

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

`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.

`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 its show `pixbuf`.

`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.

`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.

`cell_view` : | a GtkCellView
Returns : | a GtkTreeModel used or `NULL`. [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.

`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);

`cell_view` : | a GtkCellView
Returns : | the currently displayed row or `NULL`

Since 2.6

### gtk_cell_view_get_size_of_row ()

    gboolean            gtk_cell_view_get_size_of_row       (GtkCellView *cell_view,
                                                             GtkTreePath *path,

### Warning

`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`.

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

Since 2.6

### gtk_cell_view_set_background_color ()

    void                gtk_cell_view_set_background_color  (GtkCellView *cell_view,
                                                             const GdkColor *color);

`cell_view` : | a GtkCellView
`rgba` : | the new background color

Since 3.0

### gtk_cell_view_set_draw_sensitive ()

    void                gtk_cell_view_set_draw_sensitive    (GtkCellView *cell_view,

Sets whether `cell_view` should draw all of its cells in a sensitive state, this is used by GtkComboBox menus to ensure that rows with insensitive cells that contain children appear sensitive in the parent menu item.

`cell_view` : | a GtkCellView
`draw_sensitive` : | whether to draw all cells in a sensitive state.

Since 3.0

### gtk_cell_view_get_draw_sensitive ()

    gboolean            gtk_cell_view_get_draw_sensitive    (GtkCellView *cell_view);

Whether this tag affects the background color.

Default value: FALSE

### The `"cell-area"` property

      "cell-area"                GtkCellArea*          : Read / Write / Construct Only

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.

since 3.0

### The `"cell-area-context"` property

      "cell-area-context"        GtkCellAreaContext*   : Read / Write / Construct Only

The GtkCellAreaContext used to compute the geometry of the cell view.

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

### The `"draw-sensitive"` property

      "draw-sensitive"           gboolean              : Read / Write

Whether all cells should be draw as sensitive for this view regardless of the actual cell properties (used to make menus with submenus appear sensitive when the items in submenus might be insensitive).

since 3.0

Default value: FALSE

### The `"fit-model"` property

      "fit-model"                gboolean              : Read / Write

Whether the view should request enough space to always fit the size of every row in the model (used by the combo box to ensure the combo box size doesnt change when different items are selected).

since 3.0

Default value: FALSE

### The `"model"` property

      "model"                    GtkTreeModel*         : Read / Write

The model for cell view
