Class Details¶
- class Gtk.Notebook(**kwargs)¶
- Bases:
- Abstract:
No
- Structure:
The
Gtk.Notebook
widget is aGtk.Container
whose children are pages that can be switched between using tab labels along one edge.There are many configuration options for
Gtk.Notebook
. Among other things, you can choose on which edge the tabs appear (seeGtk.Notebook.set_tab_pos
()), whether, if there are too many tabs to fit the notebook should be made bigger or scrolling arrows added (seeGtk.Notebook.set_scrollable
()), and whether there will be a popup menu allowing the users to switch pages. (seeGtk.Notebook.popup_enable
(),Gtk.Notebook.popup_disable
())The
Gtk.Notebook
implementation of theGtk.Buildable
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.An example of a UI definition fragment with
Gtk.Notebook
:<object class="GtkNotebook"> <child> <object class="GtkLabel" id="notebook-content"> <property name="label">Content</property> </object> </child> <child type="tab"> <object class="GtkLabel" id="notebook-tab"> <property name="label">Tab</property> </object> </child> </object>
- CSS nodes
notebook ├── header.top │ ├── [<action widget>] │ ├── tabs │ │ ├── [arrow] │ │ ├── tab │ │ │ ╰── <tab label> ┊ ┊ ┊ │ │ ├── tab[.reorderable-page] │ │ │ ╰── <tab label> │ │ ╰── [arrow] │ ╰── [<action widget>] │ ╰── stack ├── <child> ┊ ╰── <child>
Gtk.Notebook
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.

- Parameters:
child (
Gtk.Widget
) – the child widgetmenu_label (
Gtk.Widget
orNone
) – the menu label, orNone
for default
Changes the menu label for the page containing child.
- Parameters:
child (
Gtk.Widget
) – the child widgetmenu_text (
str
) – the label text
Creates a new label and sets it as the menu label of child.
- set_scrollable(scrollable)[source]¶
-
Sets whether the tab label area will have arrows for scrolling if there are too many tabs to fit in the area.
- set_show_border(show_border)[source]¶
-
Sets whether a bevel will be drawn around the notebook pages. This only has a visual effect when the tabs are not shown. See
Gtk.Notebook.set_show_tabs
().
- set_tab_detachable(child, detachable)[source]¶
- Parameters:
child (
Gtk.Widget
) – a childGtk.Widget
detachable (
bool
) – whether the tab is detachable or not
Sets whether the tab can be detached from self 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
Gtk.Widget
pointing to the child widget that corresponds to the dropped tab.Note that you should use
Gtk.Notebook.detach_tab
() instead ofGtk.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.static void on_drag_data_received (GtkWidget *widget, GdkDragContext *context, gint x, gint y, GtkSelectionData *data, guint info, guint time, gpointer user_data) { GtkWidget *notebook; GtkWidget **child; notebook = gtk_drag_get_source_widget (context); child = (void*) gtk_selection_data_get_data (data); // process_widget (*child); gtk_notebook_detach_tab (GTK_NOTEBOOK (notebook), *child); }
If you want a notebook to accept drags from other widgets, you will have to set your own DnD code to do it.

- Parameters:
child (
Gtk.Widget
) – the pagetab_label (
