MyGo v0.5.5 returns ui.Element as a checked value handle instead of a
pointer. Migrated with `mygo migrate-ui`, then fixed what the codemod
leaves to review:
- Element nil checks become .Valid(); absent elements are ui.Element{}.
- Input handlers and paint callbacks run outside the build pass, where
elements expire and Context methods are inert: read IsDisabled into a
local during the build, keep a ui.Handle for Focus, use c.Services()
for clipboard access, create ui.Local state during the build.
- Add core.AutoFocus: v0.5.5 records an overlay's opener after its
content builds, so same-frame autofocus lost focus restore on close.
It focuses one frame later; cascader rows defer their focus likewise.
- core.OverlayLayer identifies build passes by the root element, not
c.Now(), which repeats across passes and under the Tester clock.
- Context menus survive the opening press counted as PressedOutside;
split button tooltip no longer reorders its open menu; disabled
menubar rows pass presses to the panel; Form defers blur-started
async checks so the growing message no longer moves Submit away
from the release; Combobox drops its disabled copy now that MyGo
blocks typing under a disabled wrapper (canary flipped to a guard).
- The Tester clock is virtual: tests use Advance/Now instead of
time.Sleep/time.Now and read element state inside the view. The web
mirror advances the clock to wall time before each frame and input.
- AGENTS.md and docs describe the value Element API and the new pin.
Snapshot goldens are darwin-only and were not re-verified here.

356 ScreenRecorderControls 录屏控制
用途
开始、暂停、继续、停止录制并显示计时；录制本身由调用方实现。
最小示例
st := media.RecorderState{}
view := func(c *ui.Context) {
core.Use(c, core.Settings{})
media.ScreenRecorderControls(c, st, media.ScreenRecorderControlsOptions{
OnStart: func() { st.Status = media.RecorderRecording },
OnPause: func() { st.Status = media.RecorderPaused },
OnResume: func() { st.Status = media.RecorderRecording },
OnStop: func() { st = media.RecorderState{} },
})
}
ui.Render(view, 400, 300, 1)
参数
func ScreenRecorderControls(c *ui.Context, st RecorderState, opts ScreenRecorderControlsOptions) ui.Element
RecorderState：Status（RecorderIdle、RecorderRecording、RecorderPaused）、Elapsed。
| 字段 | 类型 | 默认值 | 含义 |
|---|---|---|---|
OnStart / OnPause / OnResume / OnStop |
func() |
必填 | 缺少任一回调时 panic。 |
Disabled |
bool |
false | 禁用。 |
状态
就绪、录制中（红点）、已暂停；状态同时用文字表示，不只靠圆点颜色。录制中的圆点不闪烁。
事件
全部通过回调报告。
键盘操作
| 按键 | 作用 |
|---|---|
| Tab | 在按钮间移动 |
| Enter / Space | 按下 |
限制
- 计时由调用方更新
Elapsed。
