    Hi
    Widgets that do not get a parent assigned, will become windows.
    So normally you would insert the imported widgets into a
    layout on the mainwindow.

        well something like
        layout = QHBoxLayout()
        layout.addWidget(button1) // button1 would be your imported widget instance

        window.setLayout(layout)
        window.show()

        window most like being mainwindow

        its a good idea to read about layouts
        https://doc.qt.io/qtforpython/overviews/layout.html
        so you know what you are using :)

          But the imported widget is defined in a class so how do I use the class in the layout of the main window?

              Hi
              but a widget is a class. ?
              so you import, you create an instance and insert into layout.

              It should not be an issue to integrate it with the code you have.
              Maybe you already have a layout. else now would be a good time to use one :)

                  So how would I create instances of the classes which have multiple widgets and then insert into the layout?

                  Thanks

                    Hi
                    what you say, classes, you mean normal python classes that use widgets or what do you mean?
                    I can't answer that as it would be either you create the master class (composite) then (if its a widget) or
                    you would create each widget by itself if the "class" if not a widget and you don't want to show it.
                    However, it really depends on what you import.

                      Basically this is an widget created inside a class. So I am importing widgets which are inside a master class. How do I instantiate this, and then insert into a layout?

                      class App2(QWidget):
                      def init(self):
                      QMainWindow.init(self)
                          pybutton = QPushButton('hi', self)
                          pybutton.resize(200,70)
                          pybutton.move(900, 50)
                          self.show()

                        Well normally one would use App2 as that is the
                        composite widget.
                        So often that makes the most sense to use as it will then init the
                        widget it uses in a proper way.

                                  "app2" is a widget created from inside class.

                                    it has to inherit QWidget or be a QWidget to be used in a layout.
                                    Else its plain impossible and you must create the inner Widgets yourself. :)

                                        Because it is a QWidget it should be able to be shown but why do I get an error and is there another way to write this code because of an error.
