…ion, context menus - Screen reader announcements for amplitude, SNR, pick details at cursor - Announce markers when navigating between picks (Alt+Left/Right) - Ctrl+Shift+D announces detailed pick info for current position - Audio sonification of seismic waveforms via WAV file + system aplay/paplay - Ctrl+Shift+A toggles sonification, Ctrl+Space plays full trace at 160x - Interactive cursor-tracking audio: 15s window at 80x on cursor stop (300ms debounce) - Ctrl+Shift+Space stops playback - DC offset removal and absolute-max normalization for clean audio - Keyboard-accessible context menus (Menu key) for picks with polarity/onset/uncertainty - Fixed context menu marker lookup via nearestMarker fallback when cursor text is stale - Fresh QActions per context menu instance to avoid state corruption from shared actions
…tion changes - itemSelected now announces 'Station N of M' with station/channel/distance/azimuth - changeFilter announces the filter name (or 'No filter') - changeUnit announces the unit type - changeRotation announces the rotation mode
- Zoom in/out announces level (Ctrl+Left/Right) - Amplitude up/down announced (Ctrl+Up/Down) - Maximize amplitudes announced (S key) - Scale reset announced (W key) - Default view restored announced (Ctrl+N) - Show all/single component toggled announced (T key)
- Sort by distance/azimuth/residual/alphabetically announced - Align on origin time / P arrivals / S arrivals announced - Show/hide theoretical arrivals, unassociated picks, spectrogram announced - Reset pick announced
- Origin committed with N phases - Arrival toggled on/off with station code - Imported N picks from other origins - Added/removed station NET.STA - Location computed: M X.X, RMS X.XX, gap X - Plot tab switches (Distance/Azimuth/TravelTime etc.) - Focal mechanism committed
- Data loaded: loaded N origins, M focal mechanisms - Journal entry success/failure - Event type and certainty combo changes - Tree selection: origin ID+time, FM ID, magnitude type+value - Fix/release origin, magnitude, focal mechanism - Preferred origin/magnitude/FM changed
- Mag type tab switches: 'Showing MLv magnitude' - Recalculate result: 'Recalculated MLv 5.2 ± 0.3 with 12 stations' - Channel activate/deactivate with counts - Station checkbox toggles: included/excluded from magnitude - Diagram hover/click: station and value info - Evaluation status changes - Tab close: magnitude removed - Magnitude created announcement - Suppression flag for programmatic updates
AmplitudeView: - Component selection, station selection, filter changes - Amplitude create/set/confirm/delete/recalculate - Amplitude commit with count, trace values at cursor CalculateAmplitudes: - Computation config on accept, filter state/type changes
- Audio sonification with WaveformAudio: Ctrl+Shift+A toggle, Ctrl+Space play full trace at 160x, Ctrl+Shift+Space stop - Interactive cursor-tracking audio: 15s window at 80x speed on cursor stop (300ms debounce), also on scroll/move - Keyboard context menu via Menu key for markers - Screen reader announcements from previous commit
AmplitudeView (QMainWindow): uses statusBar()->showMessage() for visual feedback and QAccessibleAnnouncementEvent for screen readers. OriginLocatorView, EventEdit, MagnitudeView, CalculateAmplitudes (QWidget): use QAccessibleAnnouncementEvent + SEISCOMP_DEBUG log. All were previously no-op stubs.
announceToScreenReader no longer calls statusBar()->showMessage(). Screen reader announcements are silent to sighted users, using only QAccessibleAnnouncementEvent. Direct statusBar calls for audio sonification and error states are preserved as legitimate UI feedback.
Commit dialog: announces on open and accept with evaluation status, event type, and phase count. SelectStation: filter results count, station selection in table. PickerSettings: slider release values (pre/post offset, amplitude offsets), settings saved confirmation. OriginDialog: origin coordinates on accept.
- Set QToolButton::MenuButtonPopup mode on btnCommit so the dropdown arrow is focusable and accessible via keyboard - Add Ctrl+Shift+Return shortcut to open commit options dialog directly - Update tooltip to inform users about both access methods
- Set InstantPopup mode on commit button: Space/Enter opens the menu instead of committing directly, preventing accidental commits - Menu now has 'Commit' (Ctrl+Return) for direct commit and 'With additional options...' (Ctrl+Shift+Return) for the dialog - Both accessible via keyboard without needing mouse
- Space/Enter on commit button commits immediately (original behavior) - Ctrl+Return opens 'With additional options...' commit dialog - MenuButtonPopup mode gives dropdown arrow for mouse users too
- Enter/Space: commit directly - Ctrl+Enter: show the commit popup menu - Ctrl+Shift+Enter: open 'With additional options...' dialog directly
