在QScrollArea中对齐QGridLayout行

from PyQt5.QtWidgets import QApplication, QWidget, QScrollArea, QVBoxLayout, QGridLayout, QLabel
from PyQt5.QtCore import Qt

app = QApplication([])

# 创建主窗口和滚动区域
window = QWidget()
scroll_area = QScrollArea(window)
scroll_area.setWidgetResizable(True)

# 创建QGridLayout布局管理器
grid_layout = QGridLayout()
grid_layout.setAlignment(Qt.AlignTop)  # 设置整体对齐方式为顶部对齐

# 向QGridLayout中添加子控件
for i in range(10):
    label = QLabel(f"Label {i}")
    grid_layout.addWidget(label, i, 0)  # 添加到第i行，第0列

# 将QGridLayout添加到滚动区域中
scroll_widget = QWidget()
scroll_widget.setLayout(grid_layout)
scroll_area.setWidget(scroll_widget)

# 创建垂直布局管理器，并将滚动区域添加到主窗口中
layout = QVBoxLayout(window)
layout.addWidget(scroll_area)

window.show()
app.exec()
