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.

pages := []account.SettingsPage{{ID: "general", Label: "General"}, {ID: "privacy", Label: "Privacy"}}
|
|
view := func(c *ui.Context) {
|
|
core.Use(c, core.Settings{})
|
|
account.SettingsLayout(c, &page, pages, account.SettingsLayoutOptions{}, func(id string) {
|
|
account.SettingsSection(c, "Notifications", func() {
|
|
account.SettingsRow(c, "Sound", account.SettingsRowOptions{ID: "sound"}, func() ui.Element {
|
|
return input.Switch(c, &sound, "", input.SwitchOptions{})
|
|
})
|
|
})
|
|
})
|
