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.

# 268 AgentProgress Agent 进度
|
|
|
|
## 用途
|
|
|
|
显示整体进度和当前动作文字；时长未知时用不确定模式。
|
|
|
|
## 最小示例
|
|
|
|
```go
|
|
view := func(c *ui.Context) {
|
|
core.Use(c, core.Settings{})
|
|
agent.AgentProgress(c, 0.4, agent.AgentProgressOptions{Action: "Reading ledger.md"})
|
|
}
|
|
ui.Render(view, 400, 300, 1)
|
|
```
|
|
|
|
签名：`func AgentProgress(c *ui.Context, value float64, opts AgentProgressOptions) ui.Element`。确定模式下 `value` 不在 0 到 1 时 panic。
|
|
|
|
## 参数
|
|
|
|
| 字段 | 类型 | 默认值 | 含义 |
|
|
| --- | --- | --- | --- |
|
|
| `Label` | `string` | “进度” | 进度名称。 |
|
|
| `Action` | `string` | `""` | 当前动作，如“正在读取 ledger.md”。 |
|
|
| `Indeterminate` | `bool` | `false` | 不确定模式，忽略 value。 |
|
|
| `Still` | `bool` | `false` | 停止执行中动画；系统减少动画时也自动静止。 |
|
|
|
|
## 状态
|
|
|
|
- 确定模式显示百分比；不确定模式显示流动条，减少动画时为静态条加“进行中”。
|
|
|
|
## 事件
|
|
|
|
- 无事件；当前动作以状态角色读出。
|
|
|
|
## 键盘操作
|
|
|
|
- 不获取焦点。
|
|
|
|
## 限制
|
|
|
|
- 进度值由调用方计算。
