polychron.presenters.ManageGroupRelationshipsPresenter Module

ManageGroupRelationshipsPresenter

Bases: PopupPresenter[ManageGroupRelationshipsView, Model]

Presenter for managing Residual vs Intrusive contexts

prev_dict instance-attribute 

prev_dict = {}

A dictionary containing the group relationship type between a group and the previous group

post_dict instance-attribute 

post_dict = {}

A dictionary containing the group relationship type between a group and the next group

group_relationship_dict instance-attribute 

group_relationship_dict = deepcopy(group_relationships_dict())

A dictionary of the group relationship type, indexed by (group, prev_group)

removed_nodes_tracker instance-attribute 

removed_nodes_tracker = []

A list of nodes which have been removed from the copy of the stratigraphic dag due to an absence of node or phase information

__group_relationship_dag instance-attribute 

__group_relationship_dag = DiGraph([rel for rel in (keys())])

A graph of relationships in the graph

dag instance-attribute 

dag = node_del_fixed(dag, j)

The DAG being modified throughout the group management process. Initially a copy of the stratigraphic_dag, which is mutated to become the chronological_dag

context_no_unordered instance-attribute 

context_no_unordered = [x for x in (list(nodes())) if x not in removed_nodes_tracker]

An unordered list of contexts in the modified stratigraphic dag copy

context_types instance-attribute 

context_types = ['normal' for _ in (context_no_unordered)]

The type of each context in the modified dag. normal, residual or intrusive

__group_box_drag_x instance-attribute 

__group_box_drag_x: float | None = None

x coordinate for the start of the current dragging event, in canvas coordinate space?

__group_box_drag_y instance-attribute 

__group_box_drag_y: float | None = None

y coordinate for the start of the current dragging event, in canvas coordinate space?

__group_box_widget instance-attribute 

__group_box_widget: Any | None = None

The tkinter label being dragged. Todo: This is a tkinter leak into the presenter, but that's required if the presenter is handling mouse events...

__init__ 

__init__(mediator: Mediator, view: ManageGroupRelationshipsView, model: Model) -> None

Construct a presenter for managing group relationships.

Parameters:

Name Type Description Default
mediator Mediator

The mediator for switching windows etc

 required
view ManageGroupRelationshipsView

the ManageGroupRelationshipsView

 required
model Model

The models.Model to manipulate groups within

 required

Raises:

Type Description
RuntimeError

if the Model contains an invalid set of defined group relationships. Groups must have 1 incoming relationship, 1 outgoing relationship or 1 relationship in each direction and must not form cycles

compute_box_placement 

compute_box_placement() -> dict[str, tuple[float, float, float, float]]

Compute the (initial) location of group boxes for the current model

Returns:

Type Description
dict[str, tuple[float, float, float, float]]

A tuple dictionary of tuples (x, y, w, h), keyed by the label.

on_back 

on_back() -> None

Callback for when the back button is pressed (when it exists), which updates the view to show the first phase

Formerly popupWindow3.back_func

get_coords 

get_coords() -> None

Triggered when confirming the provided layout of phase relationships.

Builds prev_dict, post_dict and group_relationship_dict based on the relative positions of the phase boxes before updating the view to the 2nd stage.

Formerly popupWindow3.get_coords

full_chronograph_func 

full_chronograph_func() -> None

renders the chronological graph and forms the prev_phase and past_phase vectors

Formerly popupWindow3.full_chronograph_func
