Struct Notebook

pub struct Notebook { /* private fields */ }

Notebook is a container whose children are pages switched between using tabs.

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

GtkNotebook as GtkBuildable

The Notebook implementation of the 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 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>

Shortcuts and Gestures

Notebook supports the following keyboard shortcuts:

• Shift+F10 or Menu opens the context menu.
• Home moves the focus to the first tab.
• End moves the focus to the last tab.

Additionally, the following signals have default keybindings:

• change-current-page
• focus-tab
• move-focus-out
• reorder-tab
• select-page

Tabs support drag-and-drop between notebooks sharing the same group-name, or to new windows by handling the ::create-window signal.

Actions

Notebook defines a set of built-in actions:

• menu.popup opens the tabs context menu.

CSS nodes

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 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, regardless of text direction.

Signals

change-current-page

Emitted when the current page should be changed.

The default bindings for this signal are Ctrl+Alt+PgUp, Ctrl+Alt+PgDn, Ctrl+PgUp and Ctrl+PgDn.

Action

create-window

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 Notebook:group-name ).

focus-tab

Emitted when a tab should be focused.

Action

move-focus-out

Emitted when focus was moved out.

The default bindings for this signal are Ctrl+Tab, Ctrl+Shift+Tab, Ctrl+←, Ctrl+→, Ctrl+↑ and Ctrl+↓.

Action

page-added

the ::page-added signal is emitted in the notebook right after a page is added to the notebook.

page-removed

the ::page-removed signal is emitted in the notebook right after a page is removed from the notebook.

page-reordered

the ::page-reordered signal is emitted in the notebook right after a page has been reordered.

reorder-tab

Emitted when the tab should be reordered.

The default bindings for this signal are Alt+Home, Alt+End, Alt+PgUp, Alt+PgDn, Alt+←, Alt+→, Alt+↑ and Alt+↓.

Action

select-page

Emitted when a page should be selected.

The default binding for this signal is ␣.

Action

switch-page

Emitted when the user or a function changes the current page.

Widget

destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when @widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering above @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

show

Emitted when @widget is shown.

state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

show_tabs

true if the tabs should be shown

pub fn set_tab_detachable(&self, child: &impl IsA<Widget>, detachable: bool)

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

Note that two notebooks must share a common group identifier (see 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 by adding to it a DropTarget controller that accepts the GType GTK_TYPE_NOTEBOOK_PAGE. The :value of said drop target will be preloaded with a NotebookPage object that corresponds to the dropped tab, so you can process the value via ::accept or ::drop signals.

Note that you should use detach_tab() instead of remove_page() 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.

⚠️ The following code is in c ⚠️

static void
on_drag_data_received (GtkWidget        *widget,
                       GdkDrop          *drop,
                       GtkSelectionData *data,
                       guint             time,
                       gpointer          user_data)
{
  GtkDrag *drag;
  GtkWidget *notebook;
  GtkWidget **child;

  drag = gtk_drop_get_drag (drop);
  notebook = g_object_get_data (drag, "gtk-notebook-drag-origin");
  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.

pub fn insert_page_menu( &self, child: &impl IsA<Widget>, tab_label: Option<&impl IsA<Widget>>, menu_label: Option<&impl IsA<Widget>>, position: Option<u32>, ) -> u32

Insert a page into @self at the given position, specifying the widget to use as the label in the popup menu.

child

the Widget to use as the contents of the page

tab_label

the Widget to be used as the label for the page, or None to use the default label, “page N”

menu_label

the widget to use as a label for the page-switch menu, if that is enabled. If None, and @tab_label is a Label or None, then the menu label will be a newly created label with the same text as @tab_label; if @tab_label is not a Label, @menu_label must be specified if the page-switch menu is to be used.

position

the index (starting at 0) at which to insert the page, or -1 to append the page after all other pages.

Returns

the index (starting from 0) of the inserted page in the notebook

pub fn page_num(&self, child: &impl IsA<Widget>) -> Option<u32>

Finds the index of the page which contains the given child widget.

child

a Widget

Returns

the index of the page containing @child, or -1 if @child is not in the notebook

pub fn prepend_page( &self, child: &impl IsA<Widget>, tab_label: Option<&impl IsA<Widget>>, ) -> u32

Prepends a page to @self.

child

the Widget to use as the contents of the page

tab_label

the Widget to be used as the label for the page, or None to use the default label, “page N”

Returns

the index (starting from 0) of the prepended page in the notebook, or -1 if function fails

pub fn prepend_page_menu( &self, child: &impl IsA<Widget>, tab_label: Option<&impl IsA<Widget>>, menu_label: Option<&impl IsA<Widget>>, ) -> u32

Prepends a page to @self, specifying the widget to use as the label in the popup menu.

child

the Widget to use as the contents of the page

tab_label

the Widget to be used as the label for the page, or None to use the default label, “page N”

menu_label

the widget to use as a label for the page-switch menu, if that is enabled. If None, and @tab_label is a Label or None, then the menu label will be a newly created label with the same text as @tab_label; if @tab_label is not a Label, @menu_label must be specified if the page-switch menu is to be used.

Returns

the index (starting from 0) of the prepended page in the notebook, or -1 if function fails

pub fn remove_page(&self, page_num: Option<u32>)

Removes a page from the notebook given its index in the notebook.

page_num

the index of a notebook page, starting from 0. If -1, the last page will be removed.

pub fn reorder_child(&self, child: &impl IsA<Widget>, position: Option<u32>)

Reorders the page containing @child, so that it appears in position @position.

If @position is greater than or equal to the number of children in the list or negative, @child will be moved to the end of the list.

child

the child to move

position

the new position, or -1 to move to the end

pub fn set_current_page(&self, page_num: Option<u32>)

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.

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.

Trait Implementations

impl Clone for Notebook

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Notebook

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Notebook

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for Notebook

type ParamSpec = ParamSpecObject

type SetValue = Notebook

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Notebook>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Notebook

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Notebook

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.
