@Generated("io.github.jwharm.JavaGI")
public final class TabBar
extends Widget
implements Accessible, Buildable, ConstraintTarget

A tab bar for TabView.

The AdwTabBar widget is a tab bar that can be used with conjunction with AdwTabView. It is typically used as a top bar within ToolbarView.

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.

Style classes
By default AdwTabBar look like a part of an AdwHeaderBar and is intended to be used directly attached to one or used as a ToolbarView toolbar. The .inline style class removes its background, so that it can be used in different contexts instead.

Constructor Details

TabBar

public TabBar(MemorySegment address)

Create a TabBar proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

TabBar

public TabBar()

Creates a new AdwTabBar.

Method Details

getType

public static Type getType()

Get the GType of the TabBar class

Returns:

the GType

asParent

protected TabBar 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

getAutohide

public boolean getAutohide()

Gets whether the tabs automatically hide.

Returns:

whether the tabs automatically hide

getEndActionWidget

public Widget getEndActionWidget()

Gets the widget shown after the tabs.

Returns:

the widget shown after the tabs

getExpandTabs

public boolean getExpandTabs()

Gets whether tabs expand to full width.

Returns:

whether tabs expand to full width.

getExtraDragPreferredAction

public Set<DragAction> getExtraDragPreferredAction()

Gets the current action during a drop on the extra_drop_target.

Returns:

the drag action of the current drop.

getExtraDragPreload

public boolean getExtraDragPreload()

Gets whether drop data should be preloaded on hover.

Returns:

whether drop data should be preloaded on hover

getInverted

public boolean getInverted()

Gets whether tabs use inverted layout.

Returns:

whether tabs use inverted layout

getIsOverflowing

public boolean getIsOverflowing()

Gets whether this TabBar is overflowing.

If TRUE, all tabs cannot be displayed at once and require scrolling.

Returns:

whether this TabBar is overflowing

getStartActionWidget

public Widget getStartActionWidget()

Gets the widget shown before the tabs.

Returns:

the widget shown before the tabs

getTabsRevealed

public boolean getTabsRevealed()

Gets whether the tabs are currently revealed.

See TabBar:autohide.

view - a tab view

setupExtraDropTarget

public void setupExtraDropTarget(Set<DragAction> actions,
 @Nullable
 @Nullable Type[] types)

 @Nullable
 @Nullable Type[] types)

Sets the supported types for this drop target.

Sets up an extra drop target on tabs.

This allows to drag arbitrary content onto tabs, for example URLs in a web browser.

If a tab is hovered for a certain period of time while dragging the content, it will be automatically selected.

The TabBar::extra-drag-drop signal can be used to handle the drop.

Parameters:

actions - the supported actions

types - all supported GTypes that can be dropped

onExtraDragDrop

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

The content must be of one of the types set up via setupExtraDropTarget(java.util.Set<org.gnome.gdk.DragAction>, org.gnome.glib.Type[]).

See Gtk.DropTarget:value.
