如何使用pyqt4将数据设置为QscrollArea

from PyQt4.QtGui import QApplication, QWidget, QVBoxLayout, QScrollArea, QLabel

app = QApplication([])

window = QWidget()

layout = QVBoxLayout()

scroll_area = QScrollArea()
scroll_area.setWidgetResizable(True)
scroll_area_content = QWidget()
scroll_area.setWidget(scroll_area_content)

scroll_area_layout = QVBoxLayout(scroll_area_content)

data = ["Data 1", "Data 2", "Data 3", "Data 4", "Data 5"]
for item in data:
    label = QLabel(item)
    scroll_area_layout.addWidget(label)

layout.addWidget(scroll_area)

window.setLayout(layout)

window.show()

app.exec_()
