init_models()

connect_signals()

Connects signals.

_refresh_icons(item_type, db_map_data)

Runs when entity classes are added or updated in the db. Refreshes icons of entities in graph.

Parameters

db_map_data (dict) – list of dictionary-items keyed by DiffDatabaseMapping instance.

_all_pruned_db_map_entity_ids()

_accepts_entity_item(item, db_map)

_graph_handle_entities_added(db_map_data)

Runs when entities are added to the db. Adds the new entities to the graph if needed.

Parameters

db_map_data (dict) – list of dictionary-items keyed by DiffDatabaseMapping instance.

_graph_handle_entities_removed(db_map_data)

Runs when entities are removed from the db. Rebuilds graph if needed.

Parameters

db_map_data (dict) – list of dictionary-items keyed by DiffDatabaseMapping instance.

_graph_handle_entities_updated(db_map_data)

Runs when entities are updated in the db.

Parameters

db_map_data (dict) – list of dictionary-items keyed by DiffDatabaseMapping instance.

_db_map_ids_by_key(db_map_data)

add_db_map_ids_to_items(db_map_data)

Goes through entity items and adds the corresponding db_map ids. This could mean either restoring removed (db_map, id) tuples previously removed, or adding new (db_map, id) tuples.

Parameters

db_map_data (dict(DiffDatabaseMapping, list)) – List of added items keyed by db_map

Returns

tuples (db_map, id) that didn’t match any item in the view.

Return type

list

_handle_entity_graph_visibility_changed(visible)

_handle_entity_tree_selection_changed_in_graph(selected)

Stores the given selection of entity tree indexes and builds graph.

rebuild_graph(_checked=False)

build_graph(persistent=False)

Builds graph from current selection of items.

Parameters

get_vertex_radius(db_map, entity_id, time_line_index)

_get_item_property(db_map, entity_id, pname, time_line_index)

Returns a tuple of (min_value, value, max_value) for given entity and property. Returns self.NOT_SPECIFIED if the property is not defined for the entity. Returns None if the property is not defined for any entity.

Returns

tuple or None

_get_fixed_pos(db_map, entity_id)

_make_layout_generator()

Returns a layout generator for the current graph.

Returns

GraphLayoutGeneratorRunnable

static convert_position(x, y)

_get_entity_offset(db_map_entity_ids)

_make_new_items(x, y)

Makes new items for the graph.

Parameters

Returns

True if graph contains any items after the operation, False otherwise

Return type

bool

_add_new_items()

start_connecting_entities(db_map, entity_class, ent_item)
