- Automatically show nav bar and thumbnail panel when loading PDF files
- Hide nav bar when switching to single-page documents
- Apply auto-toggle on initial load and document navigation
- Thumbnails are already generated via DocumentManager.open_document()
- Cache rendered image handle on startup to fix 'No document loaded' issue
- Set ViewMode::Fit as default for initial load and navigation
- Disable tooltips in header (too ugly)
- Temporarily disable main menu button (needs proper implementation)
The fix: cursor.position_in(bounds) returns RELATIVE coordinates,
but we were drawing at those relative positions directly.
Solution: Add bounds.x and bounds.y offset when drawing.
- selection.region stores relative coords (from cursor)
- when drawing: absolute = relative + bounds offset
This fixes the Y-position being too far up.
KISS principle: Widget is in stack over canvas, uses SAME coordinates!
- Mouse position = exact position to draw
- selection.region = canvas pixel coordinates
- NO relative/absolute conversion needed
- NO bounds offset calculations
Removed all the over-engineered coordinate math.
Keyboard events (Enter/Escape) are already handled globally in app.rs
subscription and work correctly with Crop mode detection.
Widget-level keyboard events don't work without focus anyway.
Only mouse events (click, drag, double-click) stay in the widget.
B1: Fixed handle positions - now uses relative coordinates correctly
- Handles are drawn at correct positions (relative to bounds)
- Conversion between screen and relative coords
B2: Added Enter and Double-click for Apply
- Enter key applies crop when selection exists
- Escape key cancels crop
- Double-click on selection center applies crop (400ms window)
- CropRegion moved to domain/document/operations/crop.rs (pure model)
- crop_types.rs renamed to crop_model.rs (honest UI model name)
- DragHandle and CropSelection stay in UI layer (where they belong)
- Clean separation: Domain has no UI concerns, UI imports from Domain
- crop(): Universal crop for all document types (delegates to type impl)
- extract_meta(): Extract metadata from any document type
- Both methods work via type erasure pattern
Refs: Migration Step 1.5
- Inspired by cosmic-viewer's crop implementation (https://codeberg.org/bhh32/cosmic-viewer)
- Add crop support for all document types (Raster, Vector, Portable)
- Implement PDF and PDF thumbnail generation with incremental loading
- Add UI refresh mechanism (tick counter + RefreshView message)
- Improve fl! macro with named parameters
- Clean up code organization (mod.rs: wiring, model.rs: state only)
Add ability to set current image as desktop wallpaper with keyboard
shortcut 'W' and icon button in Properties panel.
Supports COSMIC, GNOME, KDE, XFCE, and tiling window managers via
automatic detection and fallback mechanism.
Implementation uses wallpaper crate with custom COSMIC config file
integration and gsettings/feh fallbacks.
Mark unused message variants with #[allow(dead_code)] to indicate
they are intentionally kept for future implementation:
- OpenPath: for file dialog integration
- RefreshMetadata: for metadata panel updates
- ShowError/ClearError: for error handling UI
- NoOp: fallback/placeholder message
- Add explicit lifetimes to Element return types
- Remove unused imports (Length, button, horizontal_space, icon, Handle, self)
- Mark unused parameter with underscore prefix
This eliminates all 'hiding a lifetime' and 'unused import' warnings.
- Fork cosmic::iced viewer widget to enable external state control
- Add bidirectional state synchronization between viewer and AppModel
- Implement ViewerStateChanged message for mouse interaction feedback
- Fix pixel-perfect rendering at 100% zoom (ActualSize mode)
- Ensure smooth interaction between mouse, keyboard, and button controls
This allows zoom/pan to work via:
- Keyboard shortcuts (+/-, Ctrl+arrows)
- Future toolbar buttons
- Mouse wheel and drag (existing functionality preserved)
The viewer state now properly syncs in both directions:
- External controls (keyboard/buttons) → update viewer state via diff()
- Mouse interactions → update AppModel via ViewerStateChanged message
Closes: Zoom/pan via keyboard and buttons now functional
Replace hardcoded \"~/Pictures\" with dirs::picture_dir() which resolves
to the actual absolute path (e.g. /home/user/Pictures).
The tilde (~) in paths is not automatically expanded by Rust's PathBuf,
causing path.exists() to return false for \"~/Pictures\".
Using dirs::picture_dir() provides:
- Proper absolute path resolution
- XDG Base Directory compliance
- Fallback to home directory if Pictures doesn't exist
Note: Users with existing config files need to delete
~/.config/cosmic/org.codeberg.wfx.Noctua/v1/default_image_dir
to apply the new default."
EXIF support and display in the right panel.
New features:
- Extract basic metadata (filename, format, resolution, file size, color type)
