Model Exercise Solution

The model should now contain the following top level function:

def line_colours():
    colour_table = ["red", "blue", "black"]
    return colour_table

The view should contain the following method:

def setColours(self,options):
    self.colours.clear()
    self.colours.addItems(options)

The presenter initialisation should now be:

def __init__(self, view, data_model, colour_list):
   self.view = view
   self.data_model = data_model

   self.view.setColours(colour_list)
   # connect statements
   self.view.plotSignal.connect(self.updatePlot)

And the Main module should now pass the two models into the presenter:

def __init__(self, parent=None):
    super().__init__(parent)

    self.window = QtWidgets.QMainWindow()
    my_view = view.View()
    data_model = model.DataGenerator()
    colour_list = model.line_colours()

    self.presenter = presenter.Presenter(my_view, data_model, colour_list)
    # set the view for the main window
    self.setCentralWidget(my_view)
    self.setWindowTitle("view tutorial")
