我創建了一個pyqt5具有vertical布局的窗口。在這個垂直布局中，我添加了 2 個按鈕。默認情況下，它們垂直對齊，如下所示：如何調整按鈕的幾何形狀以在上方移動。預期輸出如下：這樣，如果我添加第三個按鈕，它就會位于按鈕 2 的下方。以下是代碼：import sysfrom PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QPushButtonclass MainWindow(QMainWindow): def __init__(self, *args, **kwargs): super(MainWindow, self).__init__(*args, **kwargs) layout = QVBoxLayout() widget = QWidget() widget.setLayout(layout) self.setCentralWidget(widget) button1 = QPushButton('Button 1', self) layout.addWidget(button1) button2 = QPushButton('Button 2', self) layout.addWidget(button2)app = QApplication(sys.argv)main_window = MainWindow()main_window.show()sys.exit(app.exec_())

您需要設置布局的對齊方式并在添加的小部件之間添加一些間距，如下所示：
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QPushButton
from PyQt5 import QtCore
class MainWindow(QMainWindow):
def __init__(self, *args, **kwargs):
super(MainWindow, self).__init__(*args, **kwargs)
layout = QVBoxLayout()
#set spacing between your widgets
layout.setSpacing(5)
#set alignment in your vertical layout
layout.setAlignment(QtCore.Qt.AlignTop)
widget = QWidget()
widget.setLayout(layout)
self.setCentralWidget(widget)
button1 = QPushButton('Button 1', self)
layout.addWidget(button1)
button2 = QPushButton('Button 2', self)
layout.addWidget(button2)
app = QApplication(sys.argv)
main_window = MainWindow()
main_window.show()
sys.exit(app.exec_())
