- VisibilityController: show on field focus, dismiss until next focus, manual show/hide/toggle overrides - FloatingWindow: resize from the corner grip, clamp to screen - WindowSettings: geometry per screen, debounced saves - DBusControl: org.sloposk.Keyboard Show/Hide/Toggle for global shortcuts - org.sloposk.keyboard.desktop so System Settings lists it as a virtual keyboard - README with build/run/layout docs Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
sloposk
iPad-style floating on-screen keyboard for Plasma Wayland. Qt 6, C++ core, QML UI.
- Flick a key down for its secondary symbol; long-press for accented alternates
- iOS shift: tap = one letter, double-tap = caps lock, hold = shift while held
- Auto-capitalization, double-space → ". ", backspace repeat → word delete
- Long-press space = trackpad; slide from
.?123onto a symbol and release - Floating: drag the bottom bar, resize from the corner; geometry is remembered per screen
Build & test
cmake -B build -G Ninja && cmake --build build
ctest --test-dir build
Needs Qt ≥ 6.8 (Quick, WaylandClient, DBus, Test), LayerShellQt, xkbcommon, wayland-protocols.
Run
KWin only offers the input-method protocol to the process it launches itself.
| Where | How |
|---|---|
| Nested session (safe) | kwin_wayland --no-lockscreen --socket sloposk-dev --width 1400 --height 900 --inputmethod $PWD/build/src/sloposk kwrite |
| Desktop | cmake --install build --prefix ~/.local, then System Settings → Keyboard → Virtual Keyboard → sloposk |
| UI only | build/src/sloposk (stays visible, types nowhere) |
Show/hide, e.g. from a global shortcut: qdbus org.sloposk.Keyboard /Keyboard org.sloposk.Keyboard.Toggle
Dev hooks: SLOPOSK_AUTOTYPE=text commits on focus; SLOPOSK_SCREENSHOT=file.png saves the window and quits.
Layouts
JSON in layouts/ (built in) or ~/.local/share/sloposk/layouts/ (overrides by id). The globe key cycles them; the system locale's comes first.
{
"id": "sv-SE", "name": "Svenska", "locale": "sv_SE",
"base": "en-US",
"layers": [{"name": "letters", "rows": [[
"q",
{"label": "e", "flick": "3", "alternates": ["é", "è"]},
{"type": "backspace", "width": 1.5}
]]}]
}

Architecture
qml/ view only
input/ touch → PointerTracker gestures → KeyboardController rules
engine/ key output → text ops (DirectEngine; prediction/swipe later)
backend/ text ops → compositor (KWin input-method-v1)
layout/ JSON → Layout → LayoutModel (geometry, hit testing)
window/ floating layer-shell placement, visibility, saved geometry
app/ D-Bus control, dev hooks
sloposk_core (everything compositor-independent, plus the Sloposk QML module) is a static library shared by the app and the tests.
