如何在pyqt5中将内容调整到主窗口，当它的几何形状固定或改变时？

Question

I am creating a custom control and want to create a row of buttons. For the beginning I started with two buttons, the code looks like that:

class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
        self.setWindowTitle("Python ")
  
        self.setGeometry(500, 600, 200, 200)

        self.UiComponents()
  
        self.show()

    def UiComponents(self):
      
            button1 = QPushButton( "", self)
            button2 = QPushButton( "", self)
            button1.setGeometry(10, 150, 100, 100)
            button2.setGeometry(150, 150, 100, 100)

The problem is that the buttons don't fit into the window (because of the geometry setting I guess). My purpose is when running the code that the main window shows for example 20 buttons in a row without being cut off (meaning regardless of the number of buttons).

How do I get the buttons or window to the correct size or how can I adjust the buttons to the main window or the main window to the content?

How do I get a row of circular buttons that meet the same requirements?

def Function(self):
xpos = 10

for i in range(5):

    button = QPushButton("".format(i+1), self)
    button.setGeometry(xpos, 150, 50, 50 )
    xpos = xpos + 50
    button.setStyleSheet("border : 1px solid black;background-color : green; border-radius : 25px")
    button.clicked.connect(lambda ch, i=i+1: self.function(i))     
    button.clicked.connect(lambda ch, i=button : self.color(i))

You need to use a layout. A simple implementation of one might be

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

        mainWidget = QWidget()
        mainLayout = QHBoxLayout()
        self.setCentralWidget(mainWidget)
        mainWidget.setLayout(mainLayout)

and then pack your buttons in like

        button1 = QPushButton("")
        button2 = QPushButton("")
        button3 = QPushButton("")
        mainLayout.addWidget(button)
        mainLayout.addWidget(button2)
        mainLayout.addWidget(button3)

In this example, they would appear in order in a horizontal column, but you there are several layout managers .
