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

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