I’m trying to change the size of my grid whenever I add a new row and keep the sizes of the prev rows, but the rows keep getting slightly squished vertically. How can I fix this?

GUI

class MyForm(Ui_Form):
    def __init__(self, parent=None):
        super().__init__()
        self.setupUi(parent)
        self.gridLayoutWidget.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding)
        self.gridLayoutWidget.setLayout(self.gridLayout)
        self.pushButton.clicked.connect(self.addNewRow)
        

    def addNewRow(self):
        new_line = QLineEdit("New Course")
        new_line.setSizePolicy(QSizePolicy.Fixed, QSizePolicy.Fixed)
        g_widget = self.gridLayoutWidget
        row_count = self.gridLayout.rowCount()
        self.gridLayout.addWidget(new_line, row_count, 0)
        self.gridLayoutWidget.resize(g_widget.width(), g_widget.height() + new_line.sizeHint().height())
        
    def addNewColumn(self):
        newLine = QLineEdit("New Course ID")
        colCount = self.gridLayout.columnCount()
        self.gridLayout.addWidget(newLine, 0, colCount)

I used .resize() to keep it from getting squished vertically, and it made the squishing slightly less but it didn’t solve the full problem.
