Pointer (Cursor) 指针（光标） macos

Every shape the mouse pointer takes — and the real name of each one

鼠标指针的每一种形态 —— 以及它们各自的本名

also called也叫: cursor, mouse pointer, mouse cursor光标、鼠标指针、鼠标光标
If you called it…如果你管它叫……: “the text cursor with little bits at the top and bottom”「上下带小横杠的那个文本光标」
“mouse stuck in text editing mode”「鼠标卡在文本编辑模式出不来」
“the arrow turns into a hand over links”「箭头移到链接上就变成小手」
“double sided arrow when resizing a window”「调窗口大小时的双向箭头」
“cursor with a plus badge when dragging to copy”「拖拽复制时光标上带个加号角标」
“the mouse becomes a no entry sign”「鼠标变成一个禁止驶入的标志」
“magnifying glass cursor with a plus in it”「里面带个加号的放大镜光标」

Hover a shape · your pointer becomes it

标本可交互 —— 点点看。Specimen is live — try it.

Set the macOS pointer with NSCursor — e.g. NSCursor.iBeam.set() — or claim a region with NSView.addCursorRect(_:cursor:) inside resetCursorRects() (SwiftUI: View.pointerStyle(_:), macOS 15+). If the pointer stays stuck as the I-beam after the mouse leaves a text view, the stale cursor rect is the bug: call window.invalidateCursorRects(for: view) so the rects rebuild.

用 NSCursor 设置 macOS 指针 —— 例如 NSCursor.iBeam.set() —— 或在 resetCursorRects() 里用 NSView.addCursorRect(_:cursor:) 认领区域（SwiftUI：View.pointerStyle(_:)，macOS 15+）。如果鼠标离开文本视图后指针还卡在 I-beam，那就是过期的 cursor rect 在作怪：调用 window.invalidateCursorRects(for: view) 让 rect 重建。

Debug prompt — when it misbehaves调试 Prompt —— 当它不听话时

Debug my macOS pointer/cursor (NSCursor, NSTrackingArea). Rule out: the cursor flickering back to arrow because cursor rects reset on every layout — drive it from cursorUpdate with a tracking area instead; push/pop or hide/unhide calls unbalanced; the spinning beach ball meaning the main thread is blocked, not a cursor bug; a hidden cursor never restored after a drag. The symptom:

调试我的 macOS 指针/光标（NSCursor、NSTrackingArea）。逐项排除：cursor rect 每次布局都重置，指针闪回箭头 —— 改用 tracking area 在 cursorUpdate 里驱动；push/pop 或 hide/unhide 调用不配对；转圈的彩虹海滩球说明主线程卡死，不是指针的 bug；拖拽结束后隐藏的指针没恢复。症状是：
