Silhouette

Creating a node graph widget in Silhouette FX.

Note

Requires Silhouette 7.x or above as previous versions don’t come built-in with its own PySide2 build or provide access to the QMainWindow object.

Here is an example where the NodeGraphQt.NodeGraph.widget can be registered as a dockable panel in the application .

import fx

from Qt import QtWidgets, QtCore
from NodeGraphQt import NodeGraph, BaseNode


# create the widget wrapper that can be docked to the main window.
class NodeGraphPanel(QtWidgets.QDockWidget):
    """
    Widget wrapper for the node graph that can be docked to
    the main window.
    """

    def __init__(self, graph, parent=None):
        super(NodeGraphPanel, self).__init__(parent)
        self.setObjectName('nodeGraphQt.NodeGraphPanel')
        self.setWindowTitle('Custom Node Graph')
        self.setWidget(graph.widget)


# create a simple test node class.
class TestNode(BaseNode):

    __identifier__ = 'nodes.silhouettefx'
    NODE_NAME = 'test node'

    def __init__(self):
        super(TestNode, self).__init__()
        self.add_input('in')
        self.add_output('out')


# create the node graph controller and register our "TestNode"
graph = NodeGraph()
graph.register_node(TestNode)

# create nodes.
node_1 = graph.create_node('nodes.silhouette.TestNode')
node_2 = graph.create_node('nodes.silhouette.TestNode')
node_3 = graph.create_node('nodes.silhouette.TestNode')

# create the node graph panel that can be docked.
sfx_graph_panel = NodeGraphPanel(graph)

# add the doc widget into the main silhouette window.
sfx_window = fx.ui.mainWindow()
sfx_window.addDockWidget(QtCore.Qt.RightDockWidgetArea, sfx_graph_panel)
