GNOME's Wayland compositor draws no window frames (it offers no
zxdg_decoration_manager_v1), so winit drew its own fallback title bar,
which ignores GNOME's theme, dark mode and button layout. PdfCraft now
asks the compositor at launch (apps/pdfcraft/src/decorations.rs) and,
where it draws no frames, turns winit's frame off and makes the tab strip
the header bar, as in GNOME's own apps
(crates/ui-egui/src/window_controls.rs):
- Minimize, maximize/restore and close in Adwaita's style (round buttons,
symbolic glyphs drawn in code, no new assets), in the order and on the
side named by org.gnome.desktop.wm.preferences button-layout, read
through gsettings; Fedora's default `appmenu:close` shows only close.
Hidden in full screen.
- Resize zones along the window's edges and L-shaped corners, above the
rest of the UI so a press there resizes instead of reaching a
scrollbar; a hairline outlines the window while it isn't maximized.
- Preferences > Use system title bar (shown only where the app draws the
frame) gives the window back winit's frame at once, without a restart
(part of #1001). Named as in VectorCraft and PhotoCraft, but GNOME draws
no title bars for apps, so on GNOME this is winit's basic frame, not
GNOME's own; the tooltip says so. Saved as `system_title_bar`;
`system-title-bar` on the control channel.
- PDFCRAFT_TITLEBAR=app|system overrides the detection.
KDE, Sway, Hyprland, COSMIC and X11 offer server-side decorations and
keep the frame their desktop draws; macOS and Windows are unchanged.
Not done: right-clicking the header bar doesn't open GNOME's window menu
(egui has no command for it), the window has no shadow or rounded
corners, the resize zones lie just inside the window rather than outside
it, and Windows still uses its system frame (the rest of #1001).
The new labels (Minimize, Maximize, Restore, Use system title bar and its
tooltip) were added to all 21 translation catalogs. These translations
have not been checked by anyone fluent in those languages and should be
reviewed. The catalogs' hashes in ATTRIBUTION.toml are updated.
Made with Claude Code (Claude Opus 5.5, medium effort). It passes the
workspace quality gates (fmt, clippy, cargo test --workspace, xtask
assets) and was checked by hand on Fedora 44 GNOME (light and dark,
maximized and not, the preference toggled live), but it has not been
exhaustively regression tested.
