Python nodeAndOutputFromScenegraphLocationString Examples

Example #1

File: depends_dag.py Project: yshaur/dependsworkflow

 def nodeInputComesFromNode(self, dagNode, input):
     """
     Given a node and one of its inputs, return a tuple containing which 
     dagNode and which of its outputs is connected to the input.
     """
     inputString = dagNode.inputValue(input.name)
     (connectedNode, connectedNodeOutput) = depends_data_packet.nodeAndOutputFromScenegraphLocationString(inputString, self)
     return (connectedNode, connectedNodeOutput)

Example #2

File: depends_property_widget.py Project: ljkart/dependsworkflow

	def dragEnterEvent(self, event):
		"""
		If the user is dragging a valid text object (correct DAG path format),
		let QT know it is okay to drop it (also, show a cute icon stating as much)
		"""
		if event.mimeData().hasFormat("text/plain"):
			outputType = self.dag.nodeOutputType(*depends_data_packet.nodeAndOutputFromScenegraphLocationString(event.mimeData().text(), self.dag))
			if outputType not in self.dagNode.dataPacketTypesAccepted():
				QtGui.QWidget.dragEnterEvent(self, event)
				return
