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.

255 CostEstimator · 费用估算
用途
显示输入、输出 token 数及按调用方单价估算的费用。
最小示例
view := func(c *ui.Context) {
core.Use(c, core.Settings{})
chat.CostEstimator(c, chat.CostEstimatorOptions{InputTokens: 12000, OutputTokens: 3400, InputPrice: 3, OutputPrice: 15})
}
ui.Render(view, 400, 300, 1)
参数
func CostEstimator(c *ui.Context, opts CostEstimatorOptions) ui.Element。另有 EstimateCost(inputTokens, outputTokens, inputPrice, outputPrice) CostEstimate。
| 字段 | 类型 | 默认值 | 含义 |
|---|---|---|---|
InputTokens, OutputTokens |
int |
0 | token 数，不能为负。 |
InputPrice, OutputPrice |
float64 |
0 | 每百万 tokens 单价，须有限且不为负。 |
Currency |
string |
"$" | 金额前缀。 |
Digits |
int |
0 → 4 | 金额小数位；负数 panic。 |
状态
只读表格：输入、输出、合计（衬线标签、酒红加粗金额）与单价说明。
事件
无。
键盘操作
不获取焦点；整体读作“预计费用 金额”。
限制
- 估算按 tokens × 单价 / 1,000,000 的浮点运算；显示按
Digits位小数四舍五入，不用于结算。
