schrodinger.ui.qt.network_visualizer module

network_visualizer.py

Description: This package is meant to visualize network-connection data. A good example of the type of data this is meant to visualize is at: http://networkx.lanl.gov/index.html While this module will allow for import of networkx files, it will not be written in such a way as to be limited to those files.

The main visualizer widget expected to be used is:

class NetworkViewer(QWidget)

Copyright Schrodinger, LLC. All rights reserved.

schrodinger.ui.qt.network_visualizer.calculateArrow(end_point, arrow_end_point, mag=4, skew=4)

Calculate how to draw an arrow at the end_point of a line, this requires the line’s other endpoint so that we know the angle at which the arrow is to be drawn.

Returns

a QPolygonF containing the arrow

Parameters

mag (int) – controls the magnitude of the arrow head smaller value smaller smaller head

class schrodinger.ui.qt.network_visualizer.NetworkNode(model, network)

Bases: PyQt5.QtWidgets.QGraphicsRectItem

This is an abstract class for the Node’s of the graph, you can subclass from this class to render the data “val”, whatever it may be.

model_scale = 1200
default_size_factor = 50
__init__(model, network)
Parameters

  • model – the model node corresponding to this view node

  • network (NetworkViewer) – the graph view to which this node view belongs

getEdges()

Retrieve all the edges connected to this node.

syncModel()
scalePosToModel(pos)
scalePosFromModel(pos)
contextMenuEvent(e)

This is triggered when right clicking on a node

hoverEnterEvent(self, QGraphicsSceneHoverEvent)
hoverLeaveEvent(self, QGraphicsSceneHoverEvent)
mousePressEvent(e)

Accept mouse events so that selection doesnt get lost (QTBUG-10138)

Without this fix, when context menu is up, mouse events get propagated to the parent and it behaves as if you did not click on a node. This causes th

mouseMoveEvent(e)

Move the item and tell the network to redraw connection lines

class schrodinger.ui.qt.network_visualizer.Graph(ggraph=None, node_class=None, edge_class=None)

Bases: object

A model class for an undirected graph. This wraps around the NetworkX Graph class and provides QT signals, a easier-to-use API, and access control.

All persistent data should be stored in self._ggraph.

Note that Graph itself cannot be pickled; Graph has Graph.signals, which is a QObject and cannot be pickled. For this reason selection information (which contains references to Graph) is not placed in self._ggraph, so that self._ggraph can be pickled.

__init__(ggraph=None, node_class=None, edge_class=None)

Constructs a new Graph object

Parameters

  • ggraph (networkx.Graph) – The graph underlying this graph.

  • node_class (class) – The class to represent the graph’s nodes (should be subclass of Node)

  • edge_class (class) – The class to represent the graph’s edges (should be subclass of Edge)

class schrodinger.ui.qt.network_visualizer.Node(name, graph=None)

Bases: object

Model class for Node. Wraps the NetworkX Graph.node dictionary.

x_key = 'storedX'
y_key = 'storedY'
__init__(name, graph=None)

Construct a Node object. Most of the time, this will be constructed around an existing NetworkX node (i.e. an entry in the networkx.Graph.node dict). If a graph is specified, a node of the same name must exist in the graph, or a ValueError will result.

QT signals will only be emitted if a graph is specified.

Parameters

  • name (hashable) – a unique identifier for this node

  • graph (Graph) – the graph object to which this node belongs

Variables

  • _gnode – the underlying graph node that this node wraps. In this class, we use the node name as the graph node, but any hashable object can be used.

  • _gdata – dictionary that stores data belonging to the underlying graph node.

property gnode

Return the underlying graph node object wrapped by this Node instance (not the data dictionary _gdata).

property name

Return unique string associated with this node. Convert to string for subclasses which do not necessarily use strings as graph nodes.

x()
y()
pos()

Returns the Node’s current position coordinates. Returns None if there are no coordinates.

Return type

tuple (float, float)

setX(x, signal=True)
setY(y, signal=True)
setPos(x, y, signal=True)

Set the node’s position coordinates

Parameters

  • x (float) – x coordinate

  • y (float) – y coordinate

gdata()

Directly access the node data dictionary. Use this object carefully, as directly altering its contents can lead to internal inconsistencies.

This may be wrapped to restrict access.

getData(key)

Return the requested item from the node’s data dictionary. Returns None if the key is not found.

setData(key, value, signal=True)

Set the value of an item in the node’s data dictionary.

property degree
Returns

the degree (number of edges) of the node

Return type

int

class schrodinger.ui.qt.network_visualizer.Edge(gedge, graph)

class schrodinger.ui.qt.network_visualizer.ConnectionValidator

Bases: object

Create a subclass of this and assign it using NetworkViewer.setConnectionValidator( ) to do extra work making sure node’s are compatible to connect. val1 and val2 are node1.val and node2.val

__init__()

Initialize self. See help(type(self)) for accurate signature.

validate(node1, node2)
firstNode()
setFirstNode(node)
validateSecondVal(val)
class schrodinger.ui.qt.network_visualizer.AbstractNetworkView

Bases: object

A base class for views on Graph models. Use setModel to replace the model object. Signals from the model are automatically connected to appropriate synchronization slots.

The abstract view does not provide any built-in support for effecting changes back into the model (ex. deleting nodes, changing selection). Any such operations should be implemented in the subclass by making calls directly to the model. These changes will then be automatically synchronized forward to all views.

self.nodes is a dictionary mapping model node objects to view node objects.

self.edges is a dictionary mapping pairs of model node objects to view edge objects. There is no such thing as a edge model object.

Note that all references to the word node and edge in method names refer to view objects. For example, makeNode() will make a view node, addEdge() will add an edge view object to the view.

Variables

  • MODEL_CLASS (Graph or subclass of Graph) – an instance of this class will be created as the default model when setModel

  • _sync_with_model (bool) – whether to automatically synchronize this view (and its subviews) with the model

MODEL_CLASS

alias of Graph

__init__()

Initialize self. See help(type(self)) for accurate signature.

syncAll()

Synchronize the full model and selection state.

syncRecursive()

Synchronize the full model and selection state on this view and all subviews.

setModelSyncEnabled(enable)

Enable or disable automatic synchronization with the model for this view and all subviews.

Set the model for this view and synchronize to it. Any subviews will have the model set on them as well.

Parameters

model (Graph) – the graph model

getSignalsAndSlots(model)

Get a list of signal/slot pairs for a model. This list will be used when setting a new model to disconnect the old model signals from their slots and connect the new model’s signals to those slots.

Override this method to modify or extend signals/slots in derived classes.

Parameters

schrodinger.ui.qt.network_visualizer.perp(a)
schrodinger.ui.qt.network_visualizer.seg_intersect(a1, a2, b1, b2)

Checks whether two line segments cross each other.

Parameters

  • a1 (numpy.array) – first endpoint of line segment a

  • a2 (numpy.array) – second endpoint of line segment a

  • b1 (numpy.array) – first endpoint of line segment b

  • b2 (numpy.array) – second endpoint of line segment b

Returns

whether the line segments intersect

Return type

bool

schrodinger.ui.qt.network_visualizer.fruchterman_reingold_layout(G, dim=2, pos=None, fixed=None, iterations=50, weight='weight', scale=1)

Position nodes using Fruchterman-Reingold force-directed algorithm.

Parameters

  • G – NetworkX graph

  • dim (int) – Dimension of layout

  • pos (dict) – Initial positions for nodes as a dictionary with node as keys and values as a list or tuple. If None, then use random initial positions.

  • fixed (list) – Nodes to keep fixed at initial position. optional

  • iterations (int) – Number of iterations of spring-force relaxation

  • weight (str or None) – The edge attribute that holds the numerical value used for the edge weight. If None, then all edge weights are 1.

  • scale (float) – Scale factor for positions

Return type

dict

Returns

A dictionary of positions keyed by gnode

Examples:

>>> G=nx.path_graph(4)
>>> pos=nx.spring_layout(G)

# The same using longer function name
>>> pos=nx.fruchterman_reingold_layout(G)
