TabInformation#

The TabInformation struct describes a tab. TabInformation is purely a snapshot of some of the key characteristics of the tab, intended for use in synchronous, fast, event callbacks that format GUI elements such as the window and tab title bars.

The TabInformation struct contains the following fields:

• tab_id - the identifier for the tab
• tab_index - the logical tab position within its containing window, with 0 indicating the leftmost tab
• is_active - is true if this tab is the active tab
• is_last_active - is true if this tab is the previously active tab.
• active_pane - the PaneInformation for the active pane in this tab, or nil if unavailable
• window_id - the ID of the window that contains this tab
• window_title - the title of the window that contains this tab
• tab_title - the displayed title of the tab. This may include a transient text badge.
• effective_title - the tab title without transient badges. Automatic collision suffixes remain present. If no tab title is set, this uses the active pane title when available.
• assigned_color - the generated background color assigned to this tab by the built-in tab color system, or nil if no generated color is assigned. This is useful in format-tab-title callbacks if you want to consume the built-in assignment while still customizing the tab contents.
