After working with the introduction to PySide6, I began to develop a simple GUI for an app. One thing I noticed is the requirement to add a component, like a QLabel, then having to determine where the Layout should lie.

When I'm working with a list of things that need to be input, I end up with stuff like

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # Many declarations of attributes         
        self.line_name = QLabel("Name")
        self.input_name = QInput("Example Name")
        self.line_email = QLabel("Email")
        self.input_email = QInput("[email protected]")
        self.radio1 = QRadioButton("Option 1")
        self.radio2 = QRadioButton("Option 2")
        self.radio3 = QRadioButton("Option 3")
        ...

        # Many calls to "add Layout" for each attribute
        self.layout.addWidget(self.line_name)
        self.layout.addWidget(self.input_name)
        self.layout.addWidget(self.line_email)
        self.layout.addWidget(self.input_email)
        self.layout.addWidget(self.radio1)
        self.layout.addWidget(self.radio2
        self.layout.addWidget(self.radio3
        ...

Question is: How can I avoid repetitive layout.addWidget() calls in PySide6?

    About the "why it isn't a default": 1. PyQt/PySide are bindings to the Qt library, the references you're creating are only relevant in Python and Qt has absolutely no awareness about them; 2. it's up to the developer to eventually create such attributes/references, as they're not automatically relevant (widgets can be added to a parent or layout without the need for any persistent reference, eg: self.layout.addWidget(QLabel('whatever'))); 3. it's not modular and may lead to inappropriate assumptions. For the "ways to do it better", sorry, but it's not the scope of SO to provide opinions. Commented Jul 14 at 0:52

    probably for many people it is not problem to put few lines with addWidget and others will use GUI programs to generate layout - i.e. QtDesigner, QtCreator Commented Jul 14 at 2:46
  • I would use function which returns reference to widget so I could do self.input_name = self.add(QInput("Name")). It allows to keep it also on list or in dictionary. Commented Jul 14 at 2:58

    There are many ways of solving this, all resulting in slightly different syntax and access methods after the fact - instead of being opinionated, PySide just gives you exactly what's behind and allows you to pick whatever you prefer, instead of making a specific choice like assigning to named attributes like you do. There's nothing wrong with that, it's just a choice that you can make for several reasons - it's a matter of opinion and context. Commented Jul 14 at 3:00
  • This has major disadvantage: autocompletion wont work for widget names Commented Jul 16 at 16:34
