v0.1.22

The window chrome a platform without a titlebar hands over: a frame where the compositor draws none, caption buttons where the desktop puts them, and a bar that drags by its grip.

New

• ui::window::frame wraps an app's root in the frame its window owes — a border, Theme::surface_radius corners, a shadow, and a Theme::CLIENT_INSET band that resizes from all eight directions. It reads Window::window_decorations per frame: under Decorations::Server the child comes back untouched, which is macOS, Windows, X11 and KDE. GNOME's Wayland session has never implemented xdg-decoration and answers Client whatever was asked for, and that is the case this paints. An edge tiling reports flush keeps its square corner and gives up its band.
• ui::window::resize_edge is which edge a press resizes, or None for a press on the content. The corners take their inset square and the edges take what is left between them, so the hitboxes the frame lays down need no order between them.
• titlebar::controls is the caption cluster off macOS — minimize, maximize or restore, and close. Call it at both ends of the bar with CaptionSide and the desktop decides which end fills: App::button_layout reads GNOME's gtk-decoration-layout, and a platform reporting no layout puts the three on the right. Empty in full screen, and short whatever Window::window_controls says the compositor refuses.
• titlebar::grip is the bare stretch of a bar that moves its window, zooms it on a double click and opens the desktop's window menu on a right press. It takes the free space the content leaves.
• keys::printed writes a chord nothing is bound to the way the platform writes it — secondary-s is ⌘S against Ctrl+S, while cmd-s, super-s and win-s name the platform key itself and print ⌘S against Win+S. For a label naming a chord the keymap does not own; where there is a binding, keys::shortcut cannot drift and this can.
• Theme::CLIENT_INSET is the band a client-decorated window keeps outside its content, and Theme::CAPTION_BUTTON_WIDTH one caption button.
• ui::stats reads CPU time and memory on Windows, through GetProcessTimes and GetProcessMemoryInfo. Both were blank there.

Changed

• titlebar::titlebar no longer moves the window and no longer takes a DragState — put a titlebar::grip in the bar and give it the state instead. The bar used to be one WindowControlArea::Drag, which is how Windows answers WM_NCHITTEST, and the platform takes the first control area the pointer falls in: every interactive child then had to occlude() to stay clickable, and occluding takes the scroll wheel from everything behind it. Naming the drag surface costs the controls nothing.
• The default mono face on Windows is Cascadia Mono, which ships with Windows 11 and with Terminal, in place of Consolas.
• ctrl-y redoes off macOS, beside ctrl-shift-z, in both the text field and the editor keymaps.
• bezel-ui turns on a fourth bezel-icons category, shapes, for the square a caption button maximizes with. Cargo unions features, so it is the floor for anything depending on ui.

Fixed

• ctrl-shift-c in a terminal view no longer sends ETX. It was reaching the control-byte table, so copying interrupted the foreground process; it and ctrl-shift-v now fall through for the app to bind, and ctrl-c stays SIGINT.
