The gallery

Example screens built on xpui, in a window, and the library both firmwares flash.

Using it

cargo run -p xpui-gallery
cargo run -p xpui-gallery -- --board badger2040    # a 296x128 e-ink strip
cargo run -p xpui-gallery -- --board tufty2040     # a 320x240 colour LCD

Arrows move focus, Enter opens, Backspace goes back, H is the home gesture, B walks the seven boards, Q or Escape quits. Clicking is a tap and the scroll wheel is a swipe.

Example	Shows
Controls	Slider, stepper, toggle, progress bar
Lists	Rows, subtitles, values, and how a subtitle changes row height
Dialogs	A picker over content, capturing input, dimming what is behind
Scrolling	More rows than fit, and the runtime keeping focus visible
Text	Font roles and weights, and a line running off the panel — Text paints what it is given
Typeface	Three families, and changing the one everything is set in
Developers	Everything at once on one screen: heap figures, a widget bench, a scrolling section

The badges have three keys along the bottom edge — a, b, c — and a dedicated up/down pair beside the panel, so a is Back and b confirms, in the order the framework's own row has: a key means the same thing here as on a reader. c has nothing on it. src/chord.rs reads two presses as one meaning for a board with three keys and no spare — a real shape no board here has — and ../docs/design.md says what that costs.

Checking it

The gate is the repository's; run ./build-and-test.sh from the root. This crate's tests/ are the seven-board conformance suite; ../docs/conformance.md is how to read a failure and re-bless.

Where next

../docs/conformance.md	every screen on every board, and the rule that a bless is an assertion you have made
../docs/design.md	why the suite is here, why this is a library, the double press, the cost of two typefaces
