Implemented Interfaces

GtkNotebook implements AtkImplementorIface and GtkBuildable.

Includes

#include <gtk/gtk.h>

Description

The GtkNotebook widget is a GtkContainer whose children are pages that can be switched between using tab labels along one edge.

There are many configuration options for GtkNotebook. Among other things, you can choose on which edge the tabs appear (see gtk_notebook_set_tab_pos()), whether, if there are too many tabs to fit the notebook should be made bigger or scrolling arrows added (see gtk_notebook_set_scrollable()), and whether there will be a popup menu allowing the users to switch pages. (see gtk_notebook_popup_enable(), gtk_notebook_popup_disable())

GtkNotebook as GtkBuildable

The GtkNotebook implementation of the GtkBuildable interface supports placing children into tabs by specifying “tab” as the “type” attribute of a <child> element. Note that the content of the tab must be created before the tab can be filled. A tab child can be specified without specifying a <child> type attribute.

To add a child widget in the notebooks action area, specify "action-start" or “action-end” as the “type” attribute of the <child> element.

Signal Details

The “change-current-page” signal

gboolean
user_function (GtkNotebook *notebook,

Flags: Action


The “create-window” signal

GtkNotebook*
user_function (GtkNotebook *notebook,

               gint         y,
               gpointer     user_data)

The ::create-window signal is emitted when a detachable tab is dropped on the root window.

A handler for this signal can create a window containing a notebook where the tab will be attached. It is also responsible for moving/resizing the window and adding the necessary properties to the notebook (e.g. the “group-name” ).

Parameters

notebook

the GtkNotebook emitting the signal

 

page

the tab of notebook that is being detached

 

x

the X coordinate where the drop happens

 

y

the Y coordinate where the drop happens

 

user_data

user data set when the signal handler was connected.

 

Returns

a GtkNotebook that page should be added to, or NULL.
