windowing

The persistent bar across the top of an application carrying its title, navigation, and primary actions.

A persistent strip of application icons anchored to a screen edge, holding launchers, running apps and pinned items in one row.

A small dark translucent floating window of controls that hovers over content without taking it over, common in media and creative tools.

A permanent horizontal row of menu titles (File, Edit, View) whose menus open on click and then follow the pointer along the row.

A small application controlled item living in the system menu bar or tray, usually an icon that opens a compact panel of status and controls.

The horizontal strip of primary destinations across the top of a site, usually holding the logo, the main sections and an account control.

A small panel of controls that floats just outside a window edge in visionOS, staying with the window without covering its contents.

The small corner grip that lets you drag an element or window bigger and smaller, drawn as diagonal ridges on a textarea or window corner.

A tall tabbed toolbar that replaces menus, grouping commands into labelled sections with the important ones drawn larger.

The draggable bar between two panes that changes how much room each one gets, keyboard operable as a slider between limits.

The strip along the top of a window carrying its title and window controls, and the region you drag to move the window.

A persistent bar docked to the bottom of an application holding small tools that open into panels without leaving the current page.

The cluster of close, minimise and zoom controls in a window's title bar, three coloured dots on macOS and three glyphs on Windows.

The persistent frame of an application, its header, navigation and footer, that stays put while only the content region swaps as you move around.

The recognisable outline of an app's chrome, which bars and panes it has and where they sit, used to classify one app's layout against another's.

One of a small set of proven multi pane arrangements a platform recommends, such as list detail, supporting pane and feed, instead of a new layout per screen.

The parts of a window or app that frame content rather than being content: title bars, toolbars, tab strips and address bars.

A pane, usually on the trailing edge, that shows and edits the properties of whatever is currently selected.

An application shell with three or more vertical regions, typically navigation, a list, and a reading pane, as in a mail client.

A windowing mode where two or more apps share one screen, side by side, stacked, or as freeform windows, so every app must survive being any size.

The band at the top of a screen carrying the page title, its context, and the actions that apply to the page as a whole.

A layout container that holds one destination's content inside a window, either fixed or flexible in width, combined with other panes to fill the space.

A small always on top window that keeps video or navigation visible in a corner while the reader works in another app or scrolls another page.

The frame that positions an app's persistent regions, its bars, panes and body, so each screen drops content into named slots instead of inventing its own arrangement.

A persistent vertical region alongside the main content holding navigation or secondary controls, often collapsible on narrow screens.

How an app arranges itself when one window is stretched across two displays, either keeping content clear of the seam or splitting the layout exactly at it.

A layout of two or more side by side panes where a choice in the leading pane decides what the trailing pane shows.

A thin strip along the edge of a window or screen that reports state and offers only minor actions, never the primary ones.

A secondary pane holding content that only makes sense next to the main pane, placed beside it on wide windows and below it or behind a control on narrow ones.

A named bucket for how much width an app window has, such as compact, medium and expanded, used in place of raw device categories.

A header that slides out of the way while the reader scrolls down and returns immediately on the first upward scroll, without waiting for the top of the page.

A click that both focuses an inactive surface and reaches the control underneath, instead of being spent activating the window first.

A focus model in which whatever the pointer is over receives keyboard input, without any click to claim it first.

A header that shrinks as the page scrolls, trading its large title and image for a compact bar that stays available.
