public final class TabView
extends Widget
implements Accessible, Buildable, ConstraintTarget

A dynamic tabbed container.

AdwTabView 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.

AdwTabView maintains a TabPage object for each page, which holds additional per-page properties. You can obtain the AdwTabPage for a page with getPage(org.gnome.gtk.Widget), and as the return value for append(org.gnome.gtk.Widget) and other functions for adding children.

AdwTabView 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 Notebook for use cases such as tabbed dialogs.

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

AdwTabView adds a number of global page switching and reordering shortcuts. The TabView: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.

addShortcuts(java.util.Set<org.gnome.adw.TabViewShortcuts>) and removeShortcuts(java.util.Set<org.gnome.adw.TabViewShortcuts>) can be used to manage shortcuts in a convenient way, for example:

adw_tab_view_remove_shortcuts (view, ADW_TAB_VIEW_SHORTCUT_CONTROL_HOME |
                                      ADW_TAB_VIEW_SHORTCUT_CONTROL_END);
 

CSS nodes
AdwTabView has a main CSS node with the name tabview.

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

Constructor Details

TabView

public TabView(MemorySegment address)

Create a TabView proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

TabView

public TabView()

Creates a new AdwTabView.

Method Details

getType

public static Type getType()

Get the GType of the TabView class

Returns:

the GType

asParent

protected TabView asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Widget

addPage

public TabPage addPage(Widget child,
 @Nullable
 @Nullable TabPage parent)

Adds child to this TabView 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 closePage(org.gnome.adw.TabPage)).

If parent is NULL, this function is equivalent to append(org.gnome.gtk.Widget).

Parameters:

child - a widget to add

parent - a parent page for child

Returns:

the page object representing child

addShortcuts

public void addShortcuts(Set<TabViewShortcuts> shortcuts)

Adds shortcuts for this TabView.

See TabView:shortcuts for details.

Parameters:

shortcuts - the shortcuts to add

addShortcuts

public void addShortcuts(TabViewShortcuts... shortcuts)

Adds shortcuts for this TabView.

See TabView:shortcuts for details.

Parameters:

shortcuts - the shortcuts to add

append

public TabPage append(Widget child)

Inserts child as the last non-pinned page.

Parameters:

child - a widget to add

Returns:

the page object representing child

appendPinned

public TabPage appendPinned(Widget child)

Inserts child as the last pinned page.

Parameters:

child - a widget to add

Returns:

the page object representing child

closeOtherPages

public void closeOtherPages(TabPage page)

Requests to close all pages other than page.

Parameters:

page - a page of this TabView

closePage

public void closePage(TabPage page)

Requests to close page.

Calling this function will result in the TabView::close-page signal being emitted for page. Closing the page can then be confirmed or denied via closePageFinish(org.gnome.adw.TabPage, boolean).

If the page is waiting for a closePageFinish(org.gnome.adw.TabPage, boolean) call, this function will do nothing.

The default handler for TabView::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 TabPage: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.

Parameters:

page - a page of this TabView

closePageFinish

public void closePageFinish(TabPage page,
 boolean confirm)

Completes a closePage(org.gnome.adw.TabPage) call for page.

If confirm is TRUE, page will be closed. If it's FALSE, it will be reverted to its previous state and closePage(org.gnome.adw.TabPage) can be called for it again.

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

Parameters:

page - a page of this TabView

confirm - whether to confirm or deny closing page

closePagesAfter

public void closePagesAfter(TabPage page)

Requests to close all pages after page.

Parameters:

page - a page of this TabView

closePagesBefore

public void closePagesBefore(TabPage page)

Requests to close all pages before page.

Parameters:

page - a page of this TabView

getDefaultIcon

public Icon getDefaultIcon()

Gets the default icon of this TabView.

Returns:

the default icon of this TabView.

getIsTransferringPage

public boolean getIsTransferringPage()

Whether a page is being transferred.

The corresponding property will be set to TRUE when a drag-n-drop tab transfer starts on any AdwTabView, 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.

Returns:

whether a page is being transferred

getMenuModel

public MenuModel getMenuModel()

Gets the tab context menu model for this TabView.

Returns:

the tab context menu model for this TabView

Returns:

a GtkSelectionModel for the pages of this TabView

getSelectedPage

public TabPage getSelectedPage()

Gets the currently selected page in this TabView.

Returns:

the selected page

getShortcuts

public Set<TabViewShortcuts> getShortcuts()

Gets the enabled shortcuts for this TabView.

Returns:

the shortcut mask

insert

public TabPage insert(Widget child,
 int position)

Inserts a non-pinned page at position.

It's an error to try to insert a page before a pinned page, in that case insertPinned(org.gnome.gtk.Widget, int) should be used instead.

Parameters:

child - a widget to add

position - the position to add child at, starting from 0

Returns:

the page object representing child

insertPinned

public TabPage insertPinned(Widget child,
 int position)

Inserts a pinned page at position.

It's an error to try to insert a pinned page after a non-pinned page, in that case insert(org.gnome.gtk.Widget, int) should be used instead.

public boolean reorderPage(TabPage page,
 int position)

Reorders page to position.

It's a programmer error to try to reorder a pinned page after a non-pinned one, or a non-pinned page before a pinned one.

Parameters:

page - a page of this TabView

position - the position to insert the page at, starting at 0

Returns:

whether page was moved

selectNextPage

public boolean selectNextPage()

Selects the page after the currently selected page.

If the last page was already selected, this function does nothing.

Returns:

whether the selected page was changed

selectPreviousPage

public boolean selectPreviousPage()

Selects the page before the currently selected page.

If the first page was already selected, this function does nothing.

Returns:

whether the selected page was changed

setDefaultIcon

public void setDefaultIcon(Icon defaultIcon)

Sets the default page icon for this TabView.

If a page doesn't provide its own icon via TabPage: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.

Parameters:

defaultIcon - the default icon

setMenuModel

public void setMenuModel(@Nullable
 @Nullable MenuModel menuModel)

Sets the tab context menu model for this TabView.

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

Parameters:

menuModel - a menu model

setPagePinned

public void setPagePinned(TabPage page,
 boolean pinned)

Pins or unpins page.

Pinned pages are guaranteed to be placed before all non-pinned pages; at any given moment the first TabView:n-pinned-pages pages in this TabView 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. TabPage:indicator-icon 2. A spinner if TabPage:loading is TRUE 3. TabPage:icon 4. TabView:default-icon

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

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

Changes the value of the TabPage:pinned property.

Parameters:

page - a page of this TabView

pinned - whether page should be pinned

setSelectedPage

public void setSelectedPage(TabPage selectedPage)

Sets the currently selected page in this TabView.

Parameters:

selectedPage - a page in this TabView

setShortcuts

public void setShortcuts(Set<TabViewShortcuts> shortcuts)

Sets the enabled shortcuts for this TabView.

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

addShortcuts(java.util.Set<org.gnome.adw.TabViewShortcuts>) and removeShortcuts(java.util.Set<org.gnome.adw.TabViewShortcuts>) provide a convenient way to manage individual shortcuts.

Parameters:

shortcuts - the new shortcuts

setShortcuts

public void setShortcuts(TabViewShortcuts... shortcuts)

Sets the enabled shortcuts for this TabView.

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

addShortcuts(java.util.Set<org.gnome.adw.TabViewShortcuts>) and removeShortcuts(java.util.Set<org.gnome.adw.TabViewShortcuts>) provide a convenient way to manage individual shortcuts.

Parameters:

shortcuts - the new shortcuts

transferPage

public void transferPage(TabPage page,
 TabView otherView,
 int position)

Transfers page from this TabView to otherView.

The page object will be reused.

It's a programmer error to try to insert a pinned page after a non-pinned one, or a non-pinned page before a pinned one.

Parameters:

page - a page of this TabView

otherView - the tab view to transfer the page to

position - the position to insert the page at, starting at 0

onClosePage

public SignalConnection<TabView.ClosePageCallback> onClosePage(TabView.ClosePageCallback handler)

Emitted after closePage(org.gnome.adw.TabPage) has been called for page.

The handler is expected to call closePageFinish(org.gnome.adw.TabPage, boolean) 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:

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 closePageFinish(org.gnome.adw.TabPage, boolean) 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.

The signal handler should return GDK_EVENT_STOP to stop propagation or GDK_EVENT_CONTINUE to invoke the default handler.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• TabView.ClosePageCallback.run(org.gnome.adw.TabPage)

emitClosePage

public boolean emitClosePage(TabPage page)

Emits the "close-page" signal. See onClosePage(org.gnome.adw.TabView.ClosePageCallback).

onCreateWindow

public SignalConnection<TabView.CreateWindowCallback> onCreateWindow(TabView.CreateWindowCallback handler)

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 AdwTabView that the page will be transferred into.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• TabView.CreateWindowCallback.run()

emitCreateWindow

public TabView emitCreateWindow()

Emits the "create-window" signal. See onCreateWindow(org.gnome.adw.TabView.CreateWindowCallback).

onIndicatorActivated

public SignalConnection<TabView.IndicatorActivatedCallback> onIndicatorActivated(TabView.IndicatorActivatedCallback handler)

Emitted after the indicator icon on page has been activated.

See TabPage:indicator-icon and TabPage:indicator-activatable.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• TabView.IndicatorActivatedCallback.run(org.gnome.adw.TabPage)

emitIndicatorActivated

public void emitIndicatorActivated(TabPage page)

Emits the "indicator-activated" signal. See onIndicatorActivated(org.gnome.adw.TabView.IndicatorActivatedCallback).

onPageAttached

public SignalConnection<TabView.PageAttachedCallback> onPageAttached(TabView.PageAttachedCallback handler)

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.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• TabView.PageAttachedCallback.run(org.gnome.adw.TabPage, int)

emitPageAttached

public void emitPageAttached(TabPage page,
 int position)

Emits the "page-attached" signal. See onPageAttached(org.gnome.adw.TabView.PageAttachedCallback).

onPageDetached

public SignalConnection<TabView.PageDetachedCallback> onPageDetached(TabView.PageDetachedCallback handler)

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 TabView::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 closePageFinish(org.gnome.adw.TabPage, boolean) calls.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

public void emitPageDetached(TabPage page,
 int position)

Emits the "page-detached" signal. See onPageDetached(org.gnome.adw.TabView.PageDetachedCallback).

onPageReordered

public SignalConnection<TabView.PageReorderedCallback> onPageReordered(TabView.PageReorderedCallback handler)

Emitted after page has been reordered to position.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

• TabView.PageReorderedCallback.run(org.gnome.adw.TabPage, int)

emitPageReordered

public void emitPageReordered(TabPage page,
 int position)

Emits the "page-reordered" signal. See onPageReordered(org.gnome.adw.TabView.PageReorderedCallback).

onSetupMenu

public SignalConnection<TabView.SetupMenuCallback> onSetupMenu(TabView.SetupMenuCallback handler)

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.

Parameters:
