How can I add other widgets by pressing a button on PyQt5?

ClarkyBr

Basically I'm trying to make the "Add New Row" to create another row exactly like the others above and with all those widgets (timeEdit, comboBox, doubleSpinBox). The user will add as many as they want based on their necessities.

Where do I even begin to code the button's method and how can I make use of the newly generated objects' data?

I searched online but couldn't find much, and I don't know if this is possible on PyQt 5.

Do you already know how signals/slots work?
Connect a slot to buttons clicked() signal. In that slot create the widgets you need and add them to your layout.

Yes, I know, I did it like this:

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        # ...
        self.addRowButton.clicked.connect(self.clicked)
        # ...

    def clicked(self):
       # This is the part where I'm struggling

In the slot you would append a new row to whatever layout type you are using and create new instances of widgets to put there. You will need to understand how to code to create widgets and add them to layouts.

As a separate point you probably ought to do this using a QTreeWidget or QTreeView, which have columns and allow for row insertion.

What exactly is the Problem?
You create widgets like any other objects in Python and then add them to the layout.
Take a look at the examples: https://github.com/pyqt/examples?tab=readme-ov-file

Thank you for all the help guys! I just needed to search about "Adding new widgets dynamically", but I didn't know it was called like this. This is the final result:

def addRow(self, r):
   
       self.newLayoutRow = QtWidgets.QHBoxLayout()
   
       self.newLayoutRow.setObjectName("newLayoutRow_" + str(r))
   
       self.newTimeEdit = QtWidgets.QTimeEdit(self.sorting0)
       self.newTimeEdit.setObjectName("newTimeEdit_" + str(r))
       self.mainGrid.addWidget(self.newTimeEdit, r, 0, 1, 1)
   
       self.QComboBox1 = QtWidgets.QComboBox(self.sorting0)
       self.QComboBox1.setObjectName("QComboBox1_" + str(r))
       self.newLayoutRow.addWidget(self.QComboBox1)
   
       self.QComboBox2 = QtWidgets.QComboBox(self.sorting0)
       self.QComboBox2.setObjectName("QComboBox2_" + str(r))
       self.newLayoutRow.addWidget(self.QComboBox2)
   
       self.QSpinBox = QtWidgets.QSpinBox(self.sorting0)
       self.QSpinBox.setObjectName("QSpinBox_" + str(r))
       self.newLayoutRow.addWidget(self.QSpinBox)
   
       self.mainGrid.addLayout(self.newLayoutRow, r, 1, 1, 1)

Now just need to add some for loops and it's good to go
