macOS Segmented Control
A macOS Segmented Control is a short row of joined choices. It switches a view, filter, or closely linked mode.
Another example
A Finder-style browser uses toolbar segments for icon, list, column, and gallery views.
Main parts
- 01Visible label
- 02Interaction target
- 03Current state
- 04Keyboard behavior
Use it when
Use it for a few equal modes or filters with short labels. Each choice should quickly change the same nearby content.
Do not use it when
Avoid long or wrapped labels, too many choices, and unrelated destinations. Do not hide an effect until after a separate confirmation.
Name used in code
NSSegmentedControl / SwiftUI Picker with segmented style Before you ship
Check the supported macOS versions and AppKit or SwiftUI integration. Check standard focus and keyboard behavior. Also check VoiceOver, Full Keyboard Access, window resizing, and multi-window state. When needed, check restore, localization, and reduced motion.
Outcome: Apply or review macOS Segmented Control in a native macOS app without breaking platform rules. User context: A Finder-style browser uses toolbar segments for icon, list, column, and gallery views. macOS concept or control: macOS Segmented Control. Why it fits: Use it for a few equal modes or filters with short labels. Each choice should quickly change the same nearby content. Do not use it when: Avoid long or wrapped labels, too many choices, and unrelated destinations. Do not hide an effect until after a separate confirmation. Platform requirements: List the supported macOS versions. Say whether AppKit or SwiftUI owns each part and how they connect. Define window, menu, focus, keyboard, saved state, restore, and multi-window behavior. Platform accessibility and resilience: Use the right accessibility APIs. Check VoiceOver and Full Keyboard Access. Support localization, contrast, and reduced motion when needed. Keep user state after a relaunch. Acceptance criteria: Check the behavior on supported macOS versions with a keyboard and VoiceOver. Window resizing, focus, state restore, and AppKit or SwiftUI integration work in the normal macOS way. Evidence and limits (evidence boundary): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Supported macOS versions, AppKit or SwiftUI structure, and window model. Also confirm sandbox and entitlement limits, save rules, and the accessibility goal.
