The AdwTabBar widget is a tab bar that can be used with conjunction with AdwTabView.

AdwTabBar can autohide and can optionally contain action widgets on both sides of the tabs.

When there's not enough space to show all the tabs, AdwTabBar will scroll them. Pinned tabs always stay visible and aren't a part of the scrollable area.

CSS nodes

AdwTabBar has a single CSS node with name tabbar.

Signals

extraDragDrop

type TabBarExtraDragDropCallback

Arguments

 = TabPage

page: the page matching the tab the content was dropped onto

-> GValue

value: the GValue being dropped

-> IO Bool

Returns: whether the drop was accepted for page

This signal is emitted when content is dropped onto a tab.

The content must be of one of the types set up via [methodtabBar.setup_extra_drop_target].

See DropTarget::drop.

Connect a signal handler for the extraDragDrop signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after tabBar #extraDragDrop callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTabBarExtraDragDrop :: (IsTabBar a, MonadIO m) => a -> ((?self :: a) => TabBarExtraDragDropCallback) -> m SignalHandlerId

Connect a signal handler for the extraDragDrop signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on tabBar #extraDragDrop callback

extraDragValue

type TabBarExtraDragValueCallback

Arguments

 = TabPage

page: the page matching the tab the content was dropped onto

-> GValue

value: the GValue being dropped

-> IO [DragAction]

Returns: the preferred action for the drop on page

This signal is emitted when the dropped content is preloaded.

In order for data to be preloaded, [propertytabBar:extra-drag-preload] must be set to TRUE.

The content must be of one of the types set up via [methodtabBar.setup_extra_drop_target].

See DropTarget:value.

Since: 1.3

afterTabBarExtraDragValue :: (IsTabBar a, MonadIO m) => a -> ((?self :: a) => TabBarExtraDragValueCallback) -> m SignalHandlerId

Connect a signal handler for the extraDragValue signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after tabBar #extraDragValue callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTabBarExtraDragValue :: (IsTabBar a, MonadIO m) => a -> ((?self :: a) => TabBarExtraDragValueCallback) -> m SignalHandlerId

Connect a signal handler for the extraDragValue signal, to be run before the default handler. When overloading is enabled, this is equivalent to
