    Hello,

    How do I insert this code:

    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
    
    class Widget(QWidget):
        def __init__(self, parent=None):
            super().__init__(parent)
    
            self.rubberBand = None
            self.origin = None
    
        def mousePressEvent(self, event):
            self.origin = event.pos()
            if not self.rubberBand:
                self.rubberBand = QRubberBand(QRubberBand.Rectangle, self)
            self.rubberBand.setGeometry(QRect(self.origin, QSize()))
            self.rubberBand.show()
    
        def mouseMoveEvent(self, event):
            self.rubberBand.setGeometry(QRect(self.origin, event.pos()).normalized())
    
        def mouseReleaseEvent(self, event):
            self.rubberBand.hide()
            # determine selection, for example using QRect.intersects()
            # and QRect.contains().
    
    if __name__ == "__main__":
        app = QApplication(sys.argv)
        widget = Widget()
        widget.show()
        sys.exit(app.exec_())
    

    inside this code:

    code_2

    so that when I insert an image to be able to select a part of the image with a red rectangle. I tried inserting the code under this class without any success:

    class MyMplCanvas(mpl_qt.FigureCanvasQTAgg):
    

    Basically I get this error:

    Traceback (most recent call last):
      File "code.py", line 653, in <module>
        window = OrthoView()
      File "code.py", line 279, in __init__
        self.plotCanvas = MyMplCanvas(self)
      File "code.py", line 109, in __init__
        super().__init__(parent)
      File "/home/john/Desktop/test/venv/lib/python3.8/site-packages/matplotlib/backends/backend_qt5agg.py", line 21, in __init__
        super().__init__(figure=figure)
      File "/home/john/Desktop/test/venv/lib/python3.8/site-packages/matplotlib/backends/backend_qt5.py", line 214, in __init__
        super().__init__(figure=figure)
      File "/home/john/Desktop/test/venv/lib/python3.8/site-packages/matplotlib/backend_bases.py", line 1722, in __init__
        figure.set_canvas(self)
    AttributeError: 'OrthoView' object has no attribute 'set_canvas'
    

    Any idea/help?

      I don't know what you mean or intend by "insert ... inside this code".

      Your Widget(QWidget) declares a standalone, new class named Widget which derives from QWidget and overrides some methods. But your OrthoView derives from QMainWindow, and has nothing to do with that Widget class.

      Depending on what you are trying to achieve, maybe you want to move the methods you have overridden in Widget so that they are methods in your OrthoView?

          @JonB: Ok, I will try it!! Thank you...

          UPDATE: I did what you suggest. I got this error (which I am trying to solve):

          Traceback (most recent call last):
            File "code.py", line 505, in <module>
              widget = Widget()
          NameError: name 'Widget' is not defined
          

          it indicates the error in the line

          widget = Widget()
          

          from here:

          if __name__ == "__main__":
              app = QApplication(sys.argv)
              widget = Widget()
              widget.show()
              sys.exit(app.exec_())

            hi
            But what did you do ?
            Did you move the
            def mousePressEvent(self, event):
            def mousePressEvent(self, event):
            def mouseReleaseEvent(self, event):

            to OrthoView class ?

              @mrjj Yes

              And this:

              class OrthoView(QMainWindow):
                  def __init__(self, parent=None):      
                      super().__init__(parent)
                      self.rubberBand = None
                      self.origin = None
                  .  .  .
              

              and this:

               .  .  .
              if __name__ == "__main__":
                  app = QApplication(sys.argv)
                  icon = QIcon(os.path.join(selfDir, '_static', 'orthoview.ico'))
                  app.setWindowIcon(icon)
                  window = OrthoView()
                  window.show()
                  widget = Widget()
                  widget.show()

                Hi
                Then you dont need the lines
                widget = Widget()
                widget.show()

                as that was the "old" class and now all code that it had is moved to OrthoView
                so those lines are not needed anymore.

                  Ok, the application runs, but when I try to choose area on the image with the mouse, I do not see any rectangle from rubberband...

                    Hi
                    Yes. but now you are in training of moving the code around :)

                    I think the reason that it don't work is that the OrthoView is not the one that stuff is drawn on.
                    I think it might be the Canvas class.
                    Which means that canvas class might cover the MainWindow (OrthoView)
                    and hence it gets all the mouse events.
                    But you knows best. What class actually display the image ?

                        Hi
                        I drew on top of a picture i found.
                        i dont have python so i cant run it.

                        Anyway, what class draws the image ?

                        You must have teh mouse function in that class. since its not OrthoView
                        it seems. it must be another class.

                        I tried to read the code from
                        https://github.com/Axel-Erfurt/OrthoViewLite/blob/main/OrthoViewLite.py

                        but it seems to set "Widget" as central widget so Im not sure that code is
                        current. Did it used to be that class MyMplCanvas ?

                          @mrjj: I do not know.

                          When I put the rubberband methonds on class

                          MyMplCanvas(mpl_qt.FigureCanvasQTAgg):
                          

                          I get the errors I posted on first post.

                          When I put the code on class:

                          class OrthoView(QMainWindow):
                          

                          I do not get any errors but the execution never reach the rubbeband methods. I identified it with "prints" throughout the code.

                            Hi
                            its odd.
                            what is mpl_qt.FigureCanvasQTAgg ?

                            is that a Widget class ?

                            I cant find the source of it.

                              @mrjj I do not know. However, the initial code (where the one we talk about was based) is here:
                              https://github.com/kklmn/OrthoView/blob/master/OrthoView.py

                                Hi,

                                The method override must be added to the widget that you click your mouse on. That is not the main window.

                                As for your original error, you copied the name of the class but not its implementation hence the error. QMainWindow does indeed not have a set_canvas method.

                                      Both on

                                      MyMplCanvas(mpl_qt.FigureCanvasQTAgg)
                                      

                                      and

                                      OrthoView(QMainWindow) 
                                      

                                      the methods do not run.
                                      So where else should I put the methods?

                                      "QMainWindow does indeed not have a set_canvas method." ---> What should I do in this case? I am based on ready code, I cannot build a set_canvas method

                                      Thanks!
