A title bar lays out a start, a title and an end. In the centered styles
the start and end grow alike from nothing, their padding inside them, so
a short title sits at the bar's center and a long one gives way before
whatever stands at either end; on Windows the title, or a spacer when
there is none, takes the free width before the buttons. Caption buttons
take the bar's height at the window's own rem. Tests keep an untitled
Windows bar's buttons at its end, a long Linux title before the round
buttons, a short title centered, and the buttons inside a bar at rem 8.
Windows caption buttons take the bar's height less its hairline, a new
token, instead of their row's, so they keep their height beside caps
that wrap below them. A title bar's title is an Ellipsis: on Windows it
takes the free width before the buttons and gives way; a centered title
sits inset past the lights on both sides. The controls never shrink.
Tests hold a long Windows title's close button inside a 280px bar and
wrapped caps inside their row.
A read theme's name is an Ellipsis that gives way beside its mode badge,
so a long name keeps the badge inside a 280px box. parse_hex reads #rgba
as VS Code does, each digit doubled, so a theme with a four-digit color
reads. Tests hold the badge inside the box and read #0008 as black at
0x88 alpha.
A segmented control's segments now take their labels' widths first and
share the spare room, so a label ends in an ellipsis only when the whole
strip lacks room. The thumb's insets meet the strip's padding again, and
each segment is measured from its borderless wrapper, so the thumb covers
the chosen segment exactly. Tests hold Comfortable whole at 280px and the
thumb to the chosen segment's bounds.
SegmentedControl's segments now give way when narrow, their labels
ending in an ellipsis, down to twice a control's height each; past
that the strip scrolls as before. The pill's border and padding moved
onto the scrolling strip, and the row inside it takes that floor as its
least width, so the strip scrolls exactly to its last segment. The
palette macro now writes each color's name from its field: Palette and
Syntax gain NAMES and token_mut for every color, the quiet fills too.
Tests press a density segment and each slider, and fit the density
strip in 280px with the text a step and a half larger.
settings::ThemeEditor lays a theme open: density, corners, text size,
high contrast and reduced motion, then twelve colors of the mode shown,
each a swatch that opens a picker beside its hex; each change hands the
owner a whole draft. Theme::set_palette takes an owner's palette per
mode, the colors fading to it when the mode shows; Theme::palette names
the palette the shown mode fades to; Palette::token_mut and
Syntax::token_mut reach a color by its field's name. The gallery's
theme page applies the editor to the whole gallery live, with a way
back to Ely's theme.
Resizable's grip sits inside the box's lower right corner and its edge
handles lie inside the edges, their lines on the edge; the edges use
layout::resize_edge, a resize_handle whose line shows only while
hovered, since the box draws its own border. A drag now measures from
the handle's press, kept in keyed state, so the edge follows the
pointer from the first move. Tests drag the right edge downward and
the bottom edge sideways, turn the dial without Shift, and draw a band
with Shift over a selection.
Resizable sizes a box from its right and bottom edges and a grip at
its corner, within its least and greatest size; the grip is a Tab stop
whose arrows resize a step. Rotatable turns an svg to its angle inside
a ring whose knob a drag moves, Shift snapping to 15 degrees, with the
arrows turning it a notch. SelectionArea selects items with a band
drawn on empty space, a press, Command or Shift to add, and a cursor
the arrows walk with Space to add or drop; Escape clears and
Command-A takes all. The gallery shows gpui's own drag and drop, drag
preview, double press and wheel zoom, with pointers for Sortable,
LongPress and PanZoom; pinch stays blocked, gpui 0.2.2 forwards no
magnify event.
HelpPanel lists its articles in lists::SelectableList: the list is one
stop whose cursor scrolls into view, and Enter or a double press opens
an article, focus going to All articles as before. SelectableList now
activates on Enter's release, armed by its own press, as the palette
and menus pick: an activation that moves focus left the release to
press what took it, here the way back. ContactSupport cuts a long
address in the middle and puts a Copy beside it. The lists tests move
into a folder, the release tests on their own.
navigation::Wizard keeps one focus handle for Next and Finish, so a
second press on the step before last finishes; Back that reaches the
first step, and a finished step picked by key, hand focus to Next.
Popover::with_opener hands its content a close that gives focus back:
Got it closes the hotspot's tip before the owner hides it, and the
event details close before Edit and Delete run, so focus never lands
on a panel that left the tree. The wizard's count and the setup
checklist's tally name their selectors after their words, and the bar
takes the count's own value.
OnboardingWizard runs a first run on navigation::Wizard without its
numbered steps: "Step 2 of 4" over a bar in as many parts, the step's
title, line and content, Back and Next once ready, Finish last, and
Skip for now. Hotspot pulses on a dot that opens a tip on a press or
Enter, with Got it. FeatureHighlight names something new under a New
badge, with Try it and Not now, and rises in. SetupChecklist counts
first things to do in words and a bar, offers Start on each left, eases
a check in as one gets done, and offers Hide once all are.
navigation::Wizard now keys its buttons, steps and motion by its own id
and takes on_step and on_finish at render, failing loud without them.
A Meter's name takes the free width and ends in an ellipsis while its
count stays whole, so a long quota name keeps "9 of 12 seats" inside a
280px box. `expiry` says why it refuses a date, and Expires reads
"There is no month 13." apart from "This date has passed.". Tests now
cover an American Express card's fifteen digits and four-digit code,
the address emptying once an invitation goes, a quota past its limit,
and a prompt with benefits standing as a paywall and one without as a
line.
A key's name gives way before its ends, which keep their width. The
ends and a new secret draw through typography::literal. Tests show this
device listing first and the name field emptying after Create.
New tests: Sign in waits for a password and rests while busy; Create
account waits for a name; while one provider is on its way the other
takes no press; Send again rests while a link is on its way.
LoginForm takes an email and a password, keeps one signed in on a box,
and signs in on Enter once the address reads and a password is typed;
a failed try says why above Sign in. SignupForm ticks a new password's
rules as they hold and waits for all of them and the terms.
OAuthButtons offer each provider, one spinning while the rest rest.
MagicLinkForm and ForgotPassword send a link to an address and, once
sent, say where it went and offer it again. TwoFactorInput takes a
six-digit code at once and, after one fails, clears the boxes through
forms::PinInput's new attempt, keeping its focus. The Account chapter
splits into sign-in, profile and access, and billing and team.
The accent picker's palette takes what the custom well leaves and folds
its swatches; a test puts twelve presets in a 280px box and asserts
they fold under each other inside it. The settings tests split their
appearance cases into a file of their own. AGENTS says editing takes
the owner's handler itself.
A settings row's control slot shrinks to the box, so a control's text
wraps and a palette's row folds; the font size's sample wraps in a plain
block. A notice's boxes carry their channel's name and fold under the
kind's name when narrow. canvas::panel::editing takes the owner's
handler itself: the design panels, the structure editor, the index
manager and the privacy, notice and startup settings take theirs at
render and fail loud without one. Apply fails loud if pressed while the
proxy does not read. Tests cover Apply resting on a bad port, the way
back resting at the default size and a box pressed off.
The arrows test also moves a focused tile right and back; a new test
focuses a button inside a card and shows its arrows leave the tiles.
A card given for a key with no tile fails loud, in both layouts.
Text fields paint each run's wash before selections and glyphs, so a
Highlight's background shows: the regex tester's matches, a mention's
link and markdown's code. A tile's value gives way and wraps in a narrow
box. Hex and percent escapes take two hex digits and no sign. Tests
cover each WCAG level at its edge, a clean exit's quiet badge, a
stopped container's line without load, and a reading past its limit.
WebSocketConsole draws its log through chat::MessageList, so it holds
at the newest message. EnvironmentSelector opens a secret for its own
environment only. CollectionTree takes on_move and devtools::moved
applies a drop; the gallery opens a saved request into the builder and
moves them. Tests cover the builder's refill, Send at rest, Bearer
sign-in, the indented body, the eye, a field's pick path and the log.
Double-quoted text reads all of YAML's escapes, \x, \u and \U among
them; a code that is no character, or a lone backslash at the end,
fails with its line. A map entry splits at the first colon outside
quotes, so a quoted key or list item may hold ": ". TASKS records the
third round and closes the item.
A double-quoted scalar reads \" \\ \/ \n \t \r and \0, a single-quoted
one reads '' as a quote, and a key loses either kind of quotes. An
escape YAML does not know fails with its line, and so does block text
after | or >, which the reader does not take.
YAML reads a list written at its key's own indent, as manifests do, and
a list at a map's indent ends at the next key. A `#` inside a quoted
scalar is no comment. XML reads entity references in text and
attributes, failing on one it does not know, and a text's path counts
text nodes from one. A tree's note takes at most half its row, cut with
an ellipsis, so a long value or attribute leaves the key its name.
Format and Minify fail loud if pressed while the JSON does not read.
TableStructureEditor measures its width. With room for its least width
it lines the fields up as a table whose cells take fixed shares of that
width, so what they hold is measured at its final width; in a narrower
box each field stacks on its own, its name and remove button, its type
with its flags, then its default, all inside the box. No sideways
scroll remains, so no Tab stop lies past a fold. Tests cover both.
QueryPlanViewer's step column takes the label width and the table
scrolls sideways past its least width; TableStructureEditor's rows
stretch to a least width that scrolls sideways; RedisKeyBrowser's
columns wrap below each other inside 280px. The form's rules are pure,
parse_port and ready, with unit tests; gpui tests cover saving, a new
connection refilling the form, another engine bringing its port, and a
press on a row's button leaving the row alone.
writing::begin records the owner's focus, the mind map's or the tool
layer's, through forms::Editing::returning. The field keeps its words on
Enter's release and drops them on Escape, and both hand focus back, so
the map's arrows and the board's Backspace work at once after a write.
Tab in a mind map topic being rewritten keeps the words and hands focus
back to the map; it asks for no child while the field is open, and the
map's keys wait for the field. Tests cover a new wire into a wired input
replacing the old, a connector released on its own shape linking
nothing, and a deleted whiteboard shape taking its links with it.
