title: Python. Return current cursor position and position last left mouse click
body: <p>I want to be able to define the cursor position of the last left mouse click as a point and the current cursor position as a point in real-world coordinates. The code I have so far has the Tkinter import and Math import. I have the GUI all sorted out for this part but I don't know how to define the functions to be able to display it as a label for my GUI. </p>
  
  <pre><code>class PointFrame(Frame):
      def __init__(self, master):
          Frame.__init__(self, master)
  
          self.LastClick= Label(self, text= "Last Point Clicked:")
          self.LastClick.pack(side= LEFT)
  
          self.CurrentPosition= Label(self, text="Cursor Point:")
          self.CurrentPosition.pack(side= LEFT)
  </code></pre>
  
  <p>Need to create the functions below. </p>
