Struct libadwaita::TabView

pub struct TabView { /* private fields */ }

A dynamic tabbed container.

TabView is a container which shows one child at a time. While it provides keyboard shortcuts for switching between pages, it does not provide a visible tab switcher and relies on external widgets for that, such as TabBar, TabOverview and TabButton.

TabView maintains a TabPage object for each page, which holds additional per-page properties. You can obtain the TabPage for a page with page(), and as the return value for append() and other functions for adding children.

TabView only aims to be useful for dynamic tabs in multi-window document-based applications, such as web browsers, file managers, text editors or terminals. It does not aim to replace Gtk::Notebook for use cases such as tabbed dialogs.

As such, it does not support disabling page reordering or detaching.

TabView adds a number of global page switching and reordering shortcuts. The shortcuts property can be used to manage them.

See TabViewShortcuts for the list of the available shortcuts. All of the shortcuts are enabled by default.

add_shortcuts() and remove_shortcuts() can be used to manage shortcuts in a convenient way, for example:

⚠️ The following code is in c ⚠️

adw_tab_view_remove_shortcuts (view, ADW_TAB_VIEW_SHORTCUT_CONTROL_HOME |
                                     ADW_TAB_VIEW_SHORTCUT_CONTROL_END);

CSS nodes

TabView has a main CSS node with the name tabview.

Accessibility

TabView uses the GTK_ACCESSIBLE_ROLE_TAB_PANEL for the tab pages which are the accessible parent objects of the child widgets.

Properties

default-icon

Default page icon.

If a page doesn’t provide its own icon via icon, a default icon may be used instead for contexts where having an icon is necessary.

TabBar will use default icon for pinned tabs in case the page is not loading, doesn’t have an icon and an indicator. Default icon is never used for tabs that aren’t pinned.

TabOverview will use default icon for pages with missing thumbnails.

By default, the adw-tab-icon-missing-symbolic icon is used.

Readable | Writeable

is-transferring-page

Whether a page is being transferred.

This property will be set to TRUE when a drag-n-drop tab transfer starts on any TabView, and to FALSE after it ends.

During the transfer, children cannot receive pointer input and a tab can be safely dropped on the tab view.

Readable

menu-model

Tab context menu model.

When a context menu is shown for a tab, it will be constructed from the provided menu model. Use the setup-menu signal to set up the menu actions for the particular tab.

Signals

close-page

Emitted after TabView::close_page() has been called for @page.

The handler is expected to call TabView::close_page_finish() to confirm or reject the closing.

The default handler will immediately confirm closing for non-pinned pages, or reject it for pinned pages, equivalent to the following example:

⚠️ The following code is in c ⚠️

static gboolean
close_page_cb (AdwTabView *view,
               AdwTabPage *page,
               gpointer    user_data)
{
  adw_tab_view_close_page_finish (view, page, !adw_tab_page_get_pinned (page));

  return GDK_EVENT_STOP;
}

The TabView::close_page_finish() call doesn’t have to happen inside the handler, so can be used to do asynchronous checks before confirming the closing.

A typical reason to connect to this signal is to show a confirmation dialog for closing a tab.

create-window

Emitted when a tab should be transferred into a new window.

This can happen after a tab has been dropped on desktop.

The signal handler is expected to create a new window, position it as needed and return its TabView that the page will be transferred into.

indicator-activated

Emitted after the indicator icon on @page has been activated.

See indicator-icon and indicator-activatable.

page-attached

Emitted when a page has been created or transferred to @self_.

A typical reason to connect to this signal would be to connect to page signals for things such as updating window title.

page-detached

Emitted when a page has been removed or transferred to another view.

A typical reason to connect to this signal would be to disconnect signal handlers connected in the page-attached handler.

It is important not to try and destroy the page child in the handler of this function as the child might merely be moved to another window; use child dispose handler for that or do it in sync with your TabView::close_page_finish() calls.

page-reordered

Emitted after @page has been reordered to @position.

setup-menu

Emitted when a context menu is opened or closed for @page.

If the menu has been closed, @page will be set to NULL.

It can be used to set up menu actions before showing the menu, for example disable actions not applicable to @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 [WidgetExtManual::keynav_failed()][crate::gtk::prelude::WidgetExtManual::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 GdkSurface.

This means that [WidgetExtManual::realize()][crate::gtk::prelude::WidgetExtManual::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 [WidgetExtManual::state_flags()][crate::gtk::prelude::WidgetExtManual::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 GdkSurface associated with @widget is destroyed.

This means that [WidgetExtManual::unrealize()][crate::gtk::prelude::WidgetExtManual::unrealize()] has been called or the widget has been unmapped (that is, it is going to be hidden).

Implementations

impl TabView

pub fn new() -> TabView

Creates a new TabView.

Returns

the newly created TabView

pub fn builder() -> TabViewBuilder

This method returns an instance of TabViewBuilder which can be used to create TabView objects.

pub fn add_page( &self, child: &impl IsA<Widget>, parent: Option<&TabPage> ) -> TabPage

Adds @child to @self with @parent as the parent.

This function can be used to automatically position new pages, and to select the correct page when this page is closed while being selected (see close_page()).

If @parent is NULL, this function is equivalent to append().

child

a widget to add

parent

a parent page for @child

Returns

the page object representing @child

pub fn add_shortcuts(&self, shortcuts: TabViewShortcuts)

Available on crate feature v1_2 only.

Adds @shortcuts for @self.

pub fn close_other_pages(&self, page: &TabPage)

Requests to close all pages other than @page.

page

a page of @self

pub fn close_page(&self, page: &TabPage)

Requests to close @page.

Calling this function will result in the close-page signal being emitted for @page. Closing the page can then be confirmed or denied via close_page_finish().

If the page is waiting for a close_page_finish() call, this function will do nothing.

The default handler for close-page will immediately confirm closing the page if it’s non-pinned, or reject it if it’s pinned. This behavior can be changed by registering your own handler for that signal.

If @page was selected, another page will be selected instead:

If the parent value is NULL, the next page will be selected when possible, or if the page was already last, the previous page will be selected instead.

If it’s not NULL, the previous page will be selected if it’s a descendant (possibly indirect) of the parent. If both the previous page and the parent are pinned, the parent will be selected instead.

page

a page of @self

pub fn close_page_finish(&self, page: &TabPage, confirm: bool)

Completes a close_page() call for @page.

If @confirm is TRUE, @page will be closed. If it’s FALSE, it will be reverted to its previous state and close_page() can be called for it again.

This function should not be called unless a custom handler for close-page is used.

Sets the default page icon for @self.

If a page doesn’t provide its own icon via icon, a default icon may be used instead for contexts where having an icon is necessary.

TabBar will use default icon for pinned tabs in case the page is not loading, doesn’t have an icon and an indicator. Default icon is never used for tabs that aren’t pinned.

TabOverview will use default icon for pages with missing thumbnails.

By default, the adw-tab-icon-missing-symbolic icon is used.

pub fn set_menu_model(&self, menu_model: Option<&impl IsA<MenuModel>>)

Sets the tab context menu model for @self.

When a context menu is shown for a tab, it will be constructed from the provided menu model. Use the setup-menu signal to set up the menu actions for the particular tab.

menu_model

a menu model

pub fn set_page_pinned(&self, page: &TabPage, pinned: bool)

Pins or unpins @page.

Pinned pages are guaranteed to be placed before all non-pinned pages; at any given moment the first n-pinned-pages pages in @self are guaranteed to be pinned.

When a page is pinned or unpinned, it’s automatically reordered: pinning a page moves it after other pinned pages; unpinning a page moves it before other non-pinned pages.

Pinned pages can still be reordered between each other.

TabBar will display pinned pages in a compact form, never showing the title or close button, and only showing a single icon, selected in the following order:

1. indicator-icon
2. A spinner if loading is TRUE
3. icon
4. default-icon

TabOverview will not show a thumbnail for pinned pages, and replace the close button with an unpin button. Unlike TabBar, it will still display the page’s title, icon and indicator separately.

Pinned pages cannot be closed by default, see close-page for how to override that behavior.

Changes the value of the pinned property.

pub fn connect_close_page<F: Fn(&Self, &TabPage) -> bool + 'static>( &self, f: F ) -> SignalHandlerId

Emitted after close_page() has been called for @page.

The handler is expected to call close_page_finish() to confirm or reject the closing.

The default handler will immediately confirm closing for non-pinned pages, or reject it for pinned pages, equivalent to the following example:

⚠️ The following code is in c ⚠️

static gboolean
close_page_cb (AdwTabView *view,
               AdwTabPage *page,
               gpointer    user_data)
{
  adw_tab_view_close_page_finish (view, page, !adw_tab_page_get_pinned (page));

  return GDK_EVENT_STOP;
}

The close_page_finish() call doesn’t have to happen inside the handler, so can be used to do asynchronous checks before confirming the closing.

A typical reason to connect to this signal is to show a confirmation dialog for closing a tab.

page

a page of @self_

pub fn connect_create_window<F: Fn(&Self) -> Option<TabView> + 'static>( &self, f: F ) -> SignalHandlerId

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl ParentClassIs for TabView

type Parent = Widget

impl<OT: ObjectType> PartialEq<OT> for TabView

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for TabView

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
