Complete redesign of the on-screen keyboard (used for WiFi password, KOReader, Calibre URLs) with improved layout, navigation, visual style, and new input features: **cursor mode** for text navigation, **password mode** with visibility toggle, and **URL mode** with pre-defined snippets. |**master** | **PR #1644** | |----------|-------------| | <img width="480" height="800" alt="image" src="https://github.com/user-attachments/assets/49125857-12d0-4020-b872-05d0ddbf1d94" /> | <img width="480" height="800" alt="image" src="https://github.com/user-attachments/assets/ad16656b-d66e-43dd-8697-2b85f709d7f8" /> | | **master** | **PR #1644** | |----------|-------------| | <img width="480" height="800" alt="image" src="https://github.com/user-attachments/assets/d9901251-9154-48d2-83b4-376d3223d132" /> | <img width="480" height="800" alt="image" src="https://github.com/user-attachments/assets/84b45949-ed61-4924-af1b-d570c4c61e13" /> | | ABC Mode | Symbol Mode | URL Mode | |----------|-------------|----------| | <img width="480" height="280" alt="image" src="https://github.com/user-attachments/assets/6397a82e-50b8-4d03-92e0-f707ed7c9054" /> | <img width="480" height="280" alt="image" src="https://github.com/user-attachments/assets/205d34fe-0413-49e9-9db2-30569c297ba0" /> | <img width="480" height="280" alt="image" src="https://github.com/user-attachments/assets/801ddeab-e082-4a22-a9df-c66adb1afc16" /> | | Cursor Mode | Password Toggle | |-------------|-----------------| | <img width="480" height="800" alt="image" src="https://github.com/user-attachments/assets/841773e1-7a3c-45e5-aa89-e5787255608c" /> | <img width="480" height="800" alt="image" src="https://github.com/user-attachments/assets/9487a0b3-3f47-41ed-9cd3-b24e56e342a8" /> | - Reduced from 13/11/10 columns per row to **10 uniform columns** across all rows - Keyboard now uses **90% of screen width** (was ~66%) - Row 0: Numbers `1-9, 0` with secondary symbols (`!@#$%^&*()`) - Rows 1-3: Standard QWERTY letters - Bottom row: `shift` | `#@!` | `___` | `←` | `OK` - New mode toggle key `#@!` / `abc` switches between letter and symbol layouts - Symbol layout: 4 rows (numbers, inverted symbols, paired symbols, loose symbols) - Covers all 95 printable ASCII characters - **No secondary hints, no long-press** in symbol mode (simple and direct) - SHIFT key remains visible but **disabled** in symbol mode - In `InputType::Url`, the Space key becomes a **URL toggle** button - Activating URL mode replaces the 4 content rows with a **3×3 grid of URL snippets**: - Col 0 (protocols): `https://`, `http://`, `/opds` - Col 1 (hosts/ports): `www.`, `192.168.`, `:8080` - Col 2 (domains): `.com`, `.org`, `.net` - Snippets are inserted as full strings at the cursor position - URL mode **persists** after inserting a snippet (does not auto-deactivate) - Column alignment: col 0 over ABC, col 1 over URL, col 2 over Del - Up/Down navigation maps `bottomCol - 1` / `urlCol + 1` - SHIFT disabled in URL mode - SpecMode (`abc`) exits URL mode back to ABC - SpecSpace (`URL`) toggles URL mode on/off; selection always stays on the URL button - Button styled with `KeyboardKeyType::Mode` for consistent outline - **Enter**: Long-press Up (500ms) while in keyboard mode - **Exit**: Short-press Down while in cursor mode (resets `passwordVisible`, clears toggle position) - **Navigate**: Left/Right move cursor position within text (one position per press, no continuous repeat) - **Visual**: - Keyboard mode: underline cursor (2px line + serifs) - Cursor mode: inverted block cursor (black fill + white character) - Block width adapts to the actual character width under cursor (minimum 6px for narrow chars like space) - Block position includes inter-character kerning offset for correct alignment (calculated via string-difference: `getTextWidth(before+char) - getTextWidth(before) - getTextWidth(char)`) - End-of-text: thin 6px block - Password hidden: 3-part drawing (Part 1 + block + Part 3) to prevent block overflow onto `*` characters - Toggle position: caret ("I") cursor at saved position, `[abc]`/`[***]` label with inverted selection - **Inactive key styling**: - BaseTheme: 2px outline rectangle - LyraTheme: gray filled rounded rectangle (`Color::LightGray`) - **Password toggle position**: in cursor mode (Password only), Hold Right (500ms) enters toggle — caret cursor shows saved position, `[abc]`/`[***]` label becomes selected. Press Confirm to toggle `passwordVisible`. Press Left to restore cursor to saved position. Right from toggle is a no-op. Down from toggle exits to keyboard. - `cursorPos` persists between keyboard and cursor modes - `InputType::Password` enum replaces `bool isPassword` parameter - Text is masked with `*` except for one revealed character: - Keyboard mode: reveals character at `cursorPos - 1` - Cursor mode: no reveal in display text (block cursor draws actual char directly) - **Toggle `[abc]`/`[***]`**: accessible via cursor mode — Hold Right (500ms) enters toggle position, Confirm toggles visibility, Left exits back to cursor. Caret ("I") shown at saved position while in toggle. - `passwordVisible` resets to `false` when exiting cursor mode - **Long-press Del (1.5s)**: clears all text and resets cursor to 0 - Replaced `bool isPassword` constructor parameter with `enum class InputType { Text, Password, Url }` - Callers updated: `WifiSelectionActivity`, `KOReaderSettingsActivity`, `CalibreSettingsActivity` - `"Tips:"` header followed by context-sensitive hints, centered between text field underline and keyboard as a block - ABC mode: `"Hold SELECT for UPPERCASE or secondary char"` (shift ON: `"lowercase"` variant) + `"Hold DEL to clear all text"` (only if text not empty) - ABC + `InputType::Url`: same + `"Press URL for snippets"` - Symbol mode: `"Hold DEL to clear all text"` (only if text not empty) - URL mode: `"Press ABC to exit URL mode"` + `"Hold DEL to clear all text"` (only if text not empty) - Cursor mode: `"Press DOWN to return to keyboard"` - **Phase 1**: `"Hold UP to edit entry"` — shown after 2× DEL press, auto-hides after 4s, positioned below underline - **Phase 2**: `"Press < or > to move cursor"` + dynamic password toggle hint — shown when entering cursor mode, positioned below underline, visible until exit - When `!passwordVisible`: `"Hold > then press [abc] to show password"` - When `passwordVisible`: `"Hold > then press [***] to hide password"` - When in toggle position: `"Press < to return to cursor position"` - Holding Confirm (>500ms) inserts the **alternative character** instead of the primary - Letters: long-press inserts opposite case (e.g., `a`→`A`, `A`→`a`) - Numbers/symbols (row 0): long-press inserts secondary (e.g., `0`→`)`, `)`→`0`) - Only active in ABC mode; disabled in Symbol mode and URL mode - **`InputType::Url`**: Hold SELECT on ABC rows 1+ (letters) returns primary character only (same as short press). Row 0 (symbols) still returns secondary character on Hold SELECT. - Reduced from 3 states (shift/SHIFT/LOCK) to **2 sticky states** (shift/SHIFT) - Shift stays active after typing until manually toggled off - Label: `shift` (off) / `SHIFT` (on) - `enum class SpecialKeyType { Shift, Mode, Space, Del, Ok }` replaces plain `enum` (`SpecShift`, `SpecMode`, etc.) for type safety - All switch cases updated to `SpecialKeyType::*` with `static_cast<int>()` for array indexing - `onExit()` reverted to simple `Activity::onExit()` call (half-refresh removed) - **Bottom row column mapping**: navigating up/down between content rows and bottom row uses `col/2` and `col*2` formulas for consistent positioning (10 cols ↔ 5 cols) - **URL mode column mapping**: `bottomCol - 1` / `urlCol + 1` (3 cols ↔ 5 cols) - **Wrap-around**: row 0 → up → bottom row and bottom row → down → row 0 both apply correct column mapping - **Space key**: underscore-style horizontal line (60% of key width, 3px thick) - **Delete key**: arrow `←` drawn with lines (3px thick) instead of "DEL" text - **Secondary label** (ABC row 0): small hint in top-right corner with separation from primary number - **BaseTheme**: selection uses **inverted fill** (black rect + white text) instead of `[bracket]` markers - **BaseTheme**: text field brackets drawn as **stretchable lines** that adapt to multi-line input (1px normal, 3px cursor mode) - **LyraTheme**: text field uses **fixed-width underline** (16px margins, 8px each side) instead of stretchable line (2px normal, 3px cursor mode) - **Both themes**: special keys (shift, mode, space, del, OK) have bordered/bordered-rounded rectangles - **Font size**: keyboard uses `UI_12_FONT_ID` in both themes (was `UI_10` in Base) - **Key height**: 40px in all themes for better proportions - **Layout unification**: text and password toggle are left-aligned in all themes (`keyboardCenteredText = false` for Lyra/Lyra3Covers) - **`primaryOffset` removed**: dead code eliminated from BaseTheme and LyraTheme `drawKeyboardKey` - `keyboardVerticalOffset`: per-theme vertical adjustment of keyboard position - Base: `-13`, Lyra: `-7` - `keyboardBottomKeySpacing`: independent spacing for bottom row keys - Base: `5`, Lyra: `5` - Bottom-aligned keyboard in both themes for consistent vertical positioning - Bottom row total width calculated to match content rows width (10-col based, consistent across modes) - 4px extra gap between content rows and bottom row when `bkSpacing > 0` - `keyboardCenteredText`: `false` for all themes (unified left-aligned text) - **State reset on re-entry**: `onEnter()` resets all mutable state (`symMode`, `urlMode`, `cursorMode`, `togglePos`, `passwordVisible`, `shiftState`, `selectedRow`, `selectedCol`, `rightHeld`, `rightLongHandled`, `savedCursorPos`, `rightStartCursorPos`, `delPressCount`, `hintVisible`, `hintShowTime`) — prevents stale state when re-entering the keyboard - **Bounds checking**: `insertChar`/`insertString` clamp `cursorPos` to `text.length()` before inserting - **Empty string guard**: `insertString` returns early on empty string - **`std::string::npos`**: used instead of `SIZE_MAX` for size_t sentinel (proper C++ idiom) - **`<algorithm>` header**: included for `std::max` | File | Changes | |------|---------| | `src/activities/util/KeyboardEntryActivity.h` | `InputType` enum, `KeyDef` struct, 10-col layouts, cursor/password/URL/toggle state, hints (`delPressCount`, `hintVisible`, `hintShowTime`), held vars (`rightHeld`, `rightLongHandled`, `savedCursorPos`, `rightStartCursorPos`), `mapColContentBottom` helper | | `src/activities/util/KeyboardEntryActivity.cpp` | Complete rewrite: layout rendering, symbol/cursor/password/URL modes, toggle position, long-press, contextual tips, hint phases, block cursor kerning alignment, defensive bounds checks, state reset | | `src/components/themes/BaseTheme.h` | `KeyboardKeyType` enum, new `drawTextField`/`drawKeyboardKey` signatures, `keyboardVerticalOffset`, `keyboardBottomKeySpacing` metrics | | `src/components/themes/BaseTheme.cpp` | Redesigned `drawTextField` (stretchable brackets), `drawKeyboardKey` (inverted selection, space/delete graphics, secondary label, inactive selection), removed `primaryOffset` dead code | | `src/components/themes/lyra/LyraTheme.h` | Override signatures, `keyboardVerticalOffset`, `keyboardBottomKeySpacing`, `keyboardKeyHeight` adjustments | | `src/components/themes/lyra/LyraTheme.cpp` | `drawTextField` (fixed underline), `drawKeyboardKey` (rounded rects for special keys, space/delete graphics, secondary label, inactive selection), removed `primaryOffset` dead code | | `src/components/themes/lyra/Lyra3CoversTheme.h` | `keyboardCenteredText = false`, `keyboardVerticalOffset = -7`, inherits Lyra overrides | | `src/activities/network/WifiSelectionActivity.cpp` | `bool isPassword` → `InputType::Password` | | `src/activities/settings/KOReaderSettingsActivity.cpp` | `bool isPassword` → `InputType::Text`/`InputType::Password`/`InputType::Url` | | `src/activities/settings/CalibreSettingsActivity.cpp` | `bool isPassword` → `InputType::Text`/`InputType::Password`/`InputType::Url` | -

CrossPoint Reader ++
This firmware is based on the crosspoint-reader for the XTEINK X4, a great piece of software by Dave Allie and others
Why this fork
Unfortunately the official repository suffers from too many good ideas floating around and a lack of clear governance how to deal with these contributions, so it's lacking fundamental fixes for a proper reading experience (rendering issues, sub-par sync capabilities with KOReader, a popular multi-platform open-source epub reader).
Trying to contribute enhancements / fixes became increasingly difficult as the lack of progress effectively prevented further development.
Therefore this branch focuses on real fixes and real improvements while trying to keep up to pace with developments in the main branch.
What's different
- Proper KOReader Snychronisation (including https TLS OOM fix)
- Fixes for a lot of css rendering issues
- Additional sleep screens support (information overlay, transparent pictures over current reader screen)
- Clock-Support
- Weather information panel
- Multiple under-the-hood performance improvements
- Book information screen
- Markdown-support
- WiFi captive portal support
- ...
