Module Contents

class napari_track_edit.application_menus.visualization_widget.VisualizationConfigWidget(label: str, default_opacity: float, default_contour: bool, use_contour: bool = True)

Bases: qtpy.QtWidgets.QWidget

Sliders and checkboxes for adjusting the opacity and contour display.

update_visualization

opacity

contour = None

class napari_track_edit.application_menus.visualization_widget.ColorByWidget(tracks_viewer: napari_track_edit.data_views.views_coordinator.tracks_viewer.TracksViewer)

Bases: qtpy.QtWidgets.QWidget

A “Color by” label and the dropdown picking the feature to color by.

Selecting an entry goes through TracksViewer.set_color_feature, which updates the shared colormap and rebuilds the labels, points, tracks, tree and table.

Currently, only categorical features are offered (see categorical_feature_keys), plus “None”, which paints every node one flat color.

tracks_viewer

combo

showEvent(event)

_populate(*_args) → None: Rebuild the entries and show the feature currently in use.

_on_selected(index: int) → None

class napari_track_edit.application_menus.visualization_widget.ModeWidget

Bases: qtpy.QtWidgets.QWidget

Compact radio buttons for display mode.

update_mode

radio_group

property current_mode: str

button_for_mode(mode: str) → qtpy.QtWidgets.QRadioButton

_on_toggled(button, checked)

class napari_track_edit.application_menus.visualization_widget.VisualizationWidget(viewer: napari.Viewer)

Bases: qtpy.QtWidgets.QWidget

Widget to adjust opacity and contour display in different TrackLabels layer display modes.

viewer

tracks_viewer

mode_widget

highlight_widget

foreground_widget

background_widget

color_by_widget

show_ortho_views

show_viewer_overlay

cleanup() → None

Stop following the TracksViewer, which outlives this widget.

Called by MenuManager when the dock is destroyed.

toggle_viewer_text_overlay(checked: bool): Change the visibility of the text overlay

toggle_ortho_views(checked: bool): Show or hide the ortho views, creating them the first time.

_follow_ortho_checkbox(manager) → None

Keep our checkbox in sync with the ortho views’ own checkbox.

This is a Qt-to-Qt connection, so Qt drops it when either checkbox is deleted and nothing needs to be disconnected by hand.

_update_mode(mode: str) → None: Update the display mode on the Tracksviewer

_update_widget_availability(): Update the radio buttons, show/hide the contour checkboxes when changing between contour and normal mode. Disable the background widget when the display mode is ‘All’, as there are no background labels in that case.

_update_visualization()

Apply the values from the widget and send an update signal.

Returns without touching the layer when the widgets already agree with it. This runs on every mode_updated, which includes pressing Q - and there only the enabled state of these widgets changes, never their values. Applying them anyway triggers a second update_selection, and each one re-slices the whole displayed volume: 6 s in 3D on a 1.7e9-voxel timepoint, for a result identical to the refresh set_display_mode has already done.
