src/ui/preferences.ui is an AdwPreferencesDialog whose rows are libadwaita's own -- AdwEntryRow, AdwSpinRow, AdwSwitchRow, AdwComboRow, AdwButtonRow -- instead of a label and a bare GtkEntry in a GtkBox. There is no Apply button: a row applies as it changes, which is what those widgets are designed around, and [prefs-probe] reads the settings file back after every change. The folder chooser is cancellable now, so a picker still open when the dialog closes cannot write into a row that is gone; the cancellable is also how the probe takes the cancel path without a mouse. Two traps cost a run each and are recorded in docs/claude/invariants-gtk-and-chrome.md: an AdwDialog is not a GtkWindow (it cannot parent a GtkFileDialog, and in floating mode it adds a native surface to gtk_window_get_toplevels() that is neither a widget nor a window), and a .ui that is not listed in the GResource is a Gtk-ERROR at runtime rather than a build failure -- which is exactly what the probe opening every window is for.

- (1) fix vertical lines to small to be seen: in some cases (e.g. rect waveform in @mock_upstreamer.py) the vertical lines are to thin to be visible (sometime they glitch in and out of existence):
- the antialisaing strategy with phosphore effect should be applied with more stregth
- the lines should be more tick
- the sample points should be bigger
- (2)
relative timingdone:--relative-time; see README and SPECS.md for the measured history cost.- in order to avoid problem with time jitter user can decide to go in relative time mode
- in this mode absolute signal time is only use for export
- the plot time depends just on signal sample rate and frame number, e.g.:
- user is acquiring a signal with 1MSps and 100_000 samples per udp frame
- last frame as number and previous in this case a 100_000 indexes must be skipped
- time is simply:
((<N_frame> - <N_last>) * <n_samples_per_frame> - <sample_index>) / <sample rate>(or something like that)
- (3)
named configurationsdone: one directory per source holding<name>.tomlper configuration plusactive; a configuration carries a note and the startup settings (buffer_mb,relative_time,capture_packets); the chooser lists them and the menu's Configurations… opens/saves/deletes them. - (4)
optional udp frame storage for debugging of strange behavioursdone:--capture-packets N; see README and the design note indocs/superpowers/specs/for the ring file, the popover toggle andtools/capture_to_pcap.py. - (5)
open exported binary waveforms to view/analysedone:--open FILEand the chooser's Waveforms page (the files opened before, newest first, plus Open…); the.npy's dtype names the columns, so a load restores the signals, the samples and the axis the export had, and every instrument works on it — see README anddocs/claude/invariants-data-path.md. - (6)
imporve right click menu on the plotsdone: the plot's context menu uses the main menu's row style (menu_button+.udpscope-menu, asserted byUDPSCOPE_PROBE_ROWMENU_MS: uniformlabel_x=26,h=18, the shortcut flush right), and deleting a signal is a Remove signal submenu listing that plot's traces plus All traces on this plot. - (7) in layout edit mode add the option to drag plot border to resize them (sizing should be persistant between sessesions as the layout)
- (8)
add option to automatic save the last triggered acquisitions in a cache folder and let the user replay themdone: every latch is written to<cache>/<source>/events/as a.npy(the export format), a.txtsidecar and a.bmppreview drawn from the samples; the events pane (revealed with trigger mode, switchable) lists them with time, duration, signals and rate, shows the preview, replays one through the--openloader and has Live to go back -- see README anddocs/claude/invariants-trigger-and-pinning.md. - (9)
preferences dialogdone:src/settings.{hpp,cpp}(the store: load/save/defaults, GTK-free) +src/ui_prefs.cpp(the dialog, opened from the overflow menu); the cache directory and keep count reachEventStore, the cache directory (oneevents/directory for every source, each source a folder inside) and the keep count reachEventStore, and relative time is a start-up default; whether anything is cached at all stays the trigger pane's own switch. The same dialog opens from the host selection dialog too (aPrefsFormhas no owner, so both windows hold one), where a change still reaches the run about to start.- user can choose evnt cache directory (default /.cache/udpscope//events/)
- maximum number of events to cache
- disable completly the events storage option
- enable/disable relative time mode
- interface dark/light/auto color
- defaults
- other parameters
- move the interface into
.uiresources, and to current GTK4/libadwaita widgets while doing it:
- the shortcut overview is done (
src/ui/shortcuts.ui, with the mouse gestures drawn as icons, and[help]'sui=againsttables=as the guard) - the preferences are done (
src/ui/preferences.ui:AdwPreferencesDialogwithAdwEntryRow/AdwSpinRow/AdwSwitchRow/AdwComboRow, applying as they change, no Apply button) - next: the preferences (
AdwPreferencesDialog+AdwEntryRow/AdwSpinRow/AdwSwitchRow), the help window's chrome, the source chooser and its host form, then the main window's skeleton - plan, conventions and acceptance for each slice:
