class TabOverview(**properties: Any)

Superclasses: Widget, InitiallyUnowned, Object

Implemented Interfaces: Accessible, Buildable, ConstraintTarget

A tab overview for TabView.

AdwTabOverview is a widget that can display tabs from an AdwTabView in a grid.

AdwTabOverview shows a thumbnail for each tab. By default thumbnails are static for all pages except the selected one. They can be made always live by setting live_thumbnail to TRUE, or refreshed with invalidate_thumbnail or invalidate_thumbnails otherwise.

If the pages are too tall or too wide, the thumbnails will be cropped; use thumbnail_xalign and thumbnail_yalign to control which part of the page should be visible in this case.

Pinned tabs are shown as smaller cards without thumbnails above the other tabs. Unlike in TabBar, they still have titles, as well as an unpin button.

AdwTabOverview provides search in open tabs. It searches in tab titles and tooltips, as well as keyword.

If enable_new_tab is set to TRUE, a new tab button will be shown. Connect to the create_tab signal to use it.

secondary_menu can be used to provide a secondary menu for the overview. Use it to add extra actions, e.g. to open a new window or undo closed tab.

AdwTabOverview is intended to be used as the direct child of the window, with the rest of the window contents set as the child. The child is expected to contain an TabView.

AdwTabOverview shows window buttons by default. They can be disabled by setting show_start_title_buttons and/or show_start_title_buttons and/or show_end_title_buttons to FALSE.

If search and window buttons are disabled, and secondary menu is not set, the header bar will be hidden.

Actions

AdwTabOverview defines the overview.open and overview.close actions for opening and closing itself. They can be convenient when used together with TabButton.

CSS nodes

AdwTabOverview has a single CSS node with name taboverview.
