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.

GtkNotebook has a main CSS node with name notebook, a subnode with name header and below that a subnode with name tabs which contains one subnode per tab with name tab.

If action widgets are present, their CSS nodes are placed next to the tabs node. If the notebook is scrollable, CSS nodes with name arrow are placed as first and last child of the tabs node.

The main node gets the .frame style class when the notebook has a border (see gtk_notebook_set_show_border()).

The header node gets one of the style class .top, .bottom, .left or .right, depending on where the tabs are placed. For reorderable pages, the tab node gets the .reorderable-page class.

A tab node gets the .dnd style class while it is moved with drag-and-drop.

The nodes are always arranged from left-to-right, regarldess of text direction.

Since: 2.10


gtk_notebook_set_tab_detachable ()

void
gtk_notebook_set_tab_detachable (GtkNotebook *notebook,
                                 GtkWidget *child,
                                 gboolean detachable);

Sets whether the tab can be detached from notebook to another notebook or widget.

Note that 2 notebooks must share a common group identificator (see gtk_notebook_set_group_name()) to allow automatic tabs interchange between them.

If you want a widget to interact with a notebook through DnD (i.e.: accept dragged tabs from it) it must be set as a drop destination and accept the target “GTK_NOTEBOOK_TAB”. The notebook will fill the selection with a GtkWidget** pointing to the child widget that corresponds to the dropped tab.

Note that you should use gtk_notebook_detach_tab() instead of gtk_container_remove() if you want to remove the tab from the source notebook as part of accepting a drop. Otherwise, the source notebook will think that the dragged tab was removed from underneath the ongoing drag operation, and will initiate a drag cancel animation.

gtk_notebook_set_current_page ()

void
gtk_notebook_set_current_page (GtkNotebook *notebook,
                               gint page_num);

Switches to the page number page_num .

Note that due to historical reasons, GtkNotebook refuses to switch to a page unless the child widget is visible. Therefore, it is recommended to show child widgets before adding them to a notebook.

Parameters

notebook

a GtkNotebook

 

page_num

index of the page to switch to, starting from 0. If negative, the last page will be used. If greater than the number of pages in the notebook, nothing will be done.

Notebooks with the same name will be able to exchange tabs via drag and drop. A notebook with a NULL group name will not be able to exchange tabs with any other notebook.

Parameters

notebook

a GtkNotebook

 

group_name

the name of the notebook group, or NULL to unset it.

[allow-none]

Since: 2.24


gtk_notebook_get_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
