        As already suggested, the mouse handling methods for rubber shall not be in the MainWindow but in your class that shows the image.

            Hi
            Nope, it don't work like that. the mouse function overrides that Qt must call and
            they cant be in another function.

            under
            class MyMplCanvas(mpl_qt.FigureCanvasQTAgg):
            def mousePressEvent(self, event):
            print("PRESS")

            and see if it types "PRESS" if you click on the "image"

            If it won't compile it means mpl_qt.FigureCanvasQTAgg is not a QWidget and
            its not really possible.

              @mrjj I have just tried it. It prints "PRESS"!

              But again if I move the rubberband methods under MyMplCanvas and these:

                  super().__init__(parent)
              
                  self.rubberBand = None
                  self.origin = None
              

              again the initial error...!!!

                  Ok that's good news so it is a QWidget. Then there is hope :)
                  It reacted to the mousepress!

                  What error ?

                  the set_canvas one ?

                      You do realize that your OrthoView does not have such a method ? That its base class (QMainWindow) does not either ?

                      Therefore since you are taking your code from another project, you might want to check the code of said project for that method.

                        @john_hobbyist said in Merge two pieces of code:

                        set_canvas

                        But this is not related to the RubberBand thing. ?

                        if i look in the ORG project
                        https://github.com/kklmn/OrthoView/blob/master/OrthoView.py

                        there is no such method?
                        So did you add it or where does it come from ?

                          @SGaist, @mrjj : I have posted the code previously. But again I got the code form github repository and I inserted inside the code for rubberband (all those I have posted in my initial post) I execute the python code and again the same error.... Any ideas??

                                    Hi

                                    Ok so it has NOTHING to do with the rubberband at all.
                                    Even before you try to insert that, the app was not working.

                                    So it complains about
                                    figure.set_canvas(self)

                                    So perhaps you didnt copy the figure class etc ?

                                      @mrjj I have copied everything from the github repository. The only small modification I did in rubberband code is that I changed this part:

                                      import sys
                                      
                                      from PySide2.QtCore import QRect
                                      from PySide2.QtCore import QSize
                                      from PySide2.QtWidgets import QWidget
                                      from PySide2.QtWidgets import QRubberBand
                                      from PySide2.QtWidgets import QApplication
                                      

                                      to this one:

                                      import rubberband
                                      import sys
                                      
                                      
                                      from PyQt5 import QtWidgets
                                      from PyQt5 import QtCore 
                                      
                                      
                                      from PyQt5.QtWidgets import * 
                                      from PyQt5 import QtCore, QtGui
                                      from PyQt5.QtGui import * 
                                      from PyQt5.QtCore import * 
                                      

                                      Could this be the source of the strange errors?

                                        Rather than just copying it, did you try to run the application from the repo as is ?
