Gtk.CellView
Description: Reference for Gtk.CellView

### Class

# GtkCellView

#### Description [src]

    final class Gtk.CellView : Gtk.Widget {
      /* No available fields */
    }

A widget displaying a single row of a GtkTreeModel

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 each other (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.

#### Constructors

###### gtk_cell_view_new

Creates a new `GtkCellView` widget.

###### gtk_cell_view_new_with_context

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

###### gtk_cell_view_new_with_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.

###### gtk_cell_view_new_with_text

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

###### gtk_cell_view_new_with_texture

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

#### Instance methods

###### gtk_cell_view_get_displayed_row

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

###### gtk_cell_view_get_draw_sensitive

Gets whether `cell_view` is configured to draw all of its cells in a sensitive state.

###### gtk_cell_view_get_fit_model

Gets whether `cell_view` is configured to request space to fit the entire `GtkTreeModel`.

###### gtk_cell_view_get_model

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

###### gtk_cell_view_set_displayed_row

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.

###### gtk_cell_view_set_draw_sensitive

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.

###### gtk_cell_view_set_fit_model

Sets whether `cell_view` should request space to fit the entire `GtkTreeModel`.

###### gtk_cell_view_set_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.

###### gtk_cell_layout_pack_end
