TAB CONTAINERS — a container whose children are PAGES, one visible at a time, with a strip of tabs across its top. DevExpress ships this as its Tab Container; VS Code's editor area is a split of them.

This module owns the strip: its height, its geometry and its DOM. Who is active, where the pages sit and what a press means are the container's business (dashboard.ts), exactly as the caption band's press routing is the binder's.

Properties

NameTypeDefaultDescription
inset?numberPixels between the frame and the pages — left, right, bottom, and below the strip (0.4.43). The cards of a page sit INSIDE the container's tinted frame, so two cards under one tab read as one panel; a border on the cell alone ran exactly where the cards' own borders were. Default 8; 0 puts the pages edge to edge, the look before 0.4.43.
position?'top'Where the strip sits. Only 'top' today; 'bottom' | 'start' | 'end' follow.
align?'start' | 'center' | 'end'Along the strip (default 'start', mirrored on RTL).
stretch?booleanTabs share the strip's width equally.
height?numberStrip height, px (default 30).
className?stringYour class on the strip, for per-container theming.
hidden?booleanNo strip at all (0.4.83) — DevExpress's tab container with ShowCaption="false". Nothing is reserved for it (the pages fill the frame, less inset) and nothing is on screen: no element, so no paint, no tab stop and nothing to press. Pages are switched from code — handle.activateTab(), getActiveTab() and onTabChange work as with a visible strip.
