    Hi,

    Import the class(es) from that file, instantiate this and then call show on them for example. Or put them in a layout, etc.

            So you know how to import a class from another file. The same applies to the widgets you implement in a different file.

            mywidget.py:

            from PySide2.QtWidgets import QWidget
            
            class MyWidget(QWidget):
                """My Cool Widget"""
            
            def doSomething(self):
                """Do something cool"""
            
                print("Done something cool")
            

            main.py:

            import sys
            
            from PySide2.QtWidgets import QApplication
            
            from .mywidget import MyWidget
            
            if __name__ == "__main__":
                app = QApplication(sys.argv)
                widget = MyWidget()
                widget.show()
                sys.exit(app.exec_())

              Hi

              How would I import all classes and functions at the same time and show the widgets?

                Hi how would I import all classes and functions at the same time when I have more than one widget I want to show from another file using pyqt2 instead of pyside2.

                Thanks

                  What exactly are you trying to achieve ? It looks as if you want to use something you know nothing about so please explain your use case.

                    Hi

                    I have three different types of widgets in a python file in the form of classes and functions and I want to know how I can import them all at once to another python file so that I can show them in the python file. I need to use pyqt5. Please give me examples. The types of widgets you use does not matter to me.

                    Thanks

                      Hi
                      Did you try something like
                      from .name_of_file import *

                      Also, did you see

                        Thanks I understand that now. But how would I show all the widgets once I have used the import statement.

                        Thanks

                          Hi
                          There is no magic to it.
                          The import merely makes the types (classes) known.
                          You must create instances of the classes you wish to use

                          widget = MyWidget()

                          MyWidget will of cause be another name, depending on what you import.

                              Then you open the py file and look what they are called ?
                              In any case, you need to know the classnames or function names to use them.
                              However, i think you can enumerate them as to list their names or similar in a list
                              https://stackoverflow.com/questions/1796180/how-can-i-get-a-list-of-all-classes-within-current-module-in-python
                              However, concrete names must be used to actually use them.

                                So I must no the class names if I want to import them? There is no way to import and show all the classes without having to know what they are called?

                                Thanks

                                  well you can use the * syntax to import all, but
                                  you must create instances to show them so you cant say
                                  "Import all and show them " as that is not how it works.
                                  Also if the module contains multiple widgets. Then the only option it would
                                  have was to show all widgets as separate windows as there would be no
                                  way to know in what way to combine them into a single window.
                                  However, the module could internally have multiple widgets defined and
                                  and have one widget that uses the tother so you would only need to create
                                  an instance of that one.

                                  Can you explain why you seem to hook on not using the class names?

                                    well you can use the * syntax to import all, but
                                    you must create instances to show them so you cant say
                                    "Import all and show them " as that is not how it works.

                                    Hi

                                    I want to be able to import and show widgets from any other file in current python file but the condition is I have no idea what that file contains but I should be able to still show the widgets from that file. Please show me how to do this. As simple as possible would be great.

                                    Thanks

                                      It seems you can use a string as class name and in that way maybe do it
                                      with
                                      https://stackoverflow.com/questions/553784/can-you-use-a-string-to-instantiate-a-class
                                      combined with
                                      https://stackoverflow.com/questions/1796180/how-can-i-get-a-list-of-all-classes-within-current-module-in-python
                                      so you import module , build stringlist and
                                      then use the

                                       def construct(self, builderName):
                                              targetClass = getattr(idClasses, builderName)
                                              instance = targetClass()
                                              self.allClasses.append(instance)
                                      

                                      to actually construct a list of instances.

                                      Then you can insert into your main window to show.

                                          @sdf1444 you do realise that you are basically asking us to do your work for you ? You were already given several good starting points but you didn't even show anything you tried to get things working.
