EventControllerFocus::connect_leave was firing whenever the pointer left
the launcher surface because Hyprland's focus-follows-mouse hands keyboard
focus back to the window under the cursor (OnDemand mode).
Fix: introduce a full-screen transparent backdrop window at Layer::Top.
The launcher sits at Layer::Overlay (above it), so the backdrop never
intercepts launcher clicks. Clicking anywhere outside the launcher hits
the backdrop and closes both windows via a shared Rc<dyn Fn()> callback.
The launcher returns to KeyboardMode::Exclusive so the compositor can no
longer steal focus on pointer leave. EventControllerFocus is removed.
- KeyboardMode::Exclusive → OnDemand: with Exclusive the compositor
never sends wl_keyboard::leave, so EventControllerFocus::connect_leave
never fires. OnDemand lets Hyprland hand focus back on click-outside.
- Move EventControllerKey from search to window, capture phase: bubble
phase on SearchEntry let its own handlers consume Enter and arrows
first. Capture phase on the window intercepts all keys before any
widget sees them, so Enter/Up/Down/Esc always reach our handler.
Switch KeyboardMode to Exclusive so Hyprland hands keyboard focus to
breadbox immediately on creation. Add an EventControllerFocus on the
window that calls close() the moment focus leaves (click outside,
alt-tab, compositor focus change, etc.).
Remove the wofi subprocess entirely. The launcher now renders its own
Wayland overlay window via gtk4 + gtk4-layer-shell: a SearchEntry at
the top with live fuzzy filtering, a ListBox of results below, and
keyboard navigation (Enter/Esc/arrows). Toggle (keybind press while
open closes it) is handled via a PID file in $XDG_RUNTIME_DIR.
Zero-dependency Rust rewrite of the breadboard launcher. Parses
.desktop files in-process (no awk subprocesses), builds a tab-separated
cache for wofi dmenu, and supports stale-while-revalidate background
rebuilds. Apps-only for now; icon support to be added later.
