Struct gtk4::Notebook

#[repr(transparent)]
pub struct Notebook { /* private fields */ }
Expand description

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

An example GtkNotebook

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>

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

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

Action

move-focus-out

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

Action

select-page

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.

Action

query-tooltip

Emitted when the widgets 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).

source

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 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 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.

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”

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

source

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.

source

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

source

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.
