除了明显的错字(我确定您的意思是QScrollArea
)之外,我看不出您发布的内容有任何问题。所以问题一定出在代码的其他地方:可能是缺少布局?为了确保我们在同一页面上,下面的最小脚本按我的预期工作:

PyQt5
from PyQt5 import QtWidgets
class Window(QtWidgets.QWidget):
def __init__(self, val):
super().__init__()
mygroupbox = QtWidgets.QGroupBox('this is my groupbox')
myform = QtWidgets.QFormLayout()
labellist = []
combolist = []
for i in range(val):
labellist.append(QtWidgets.QLabel('mylabel'))
combolist.append(QtWidgets.QComboBox())
myform.addRow(labellist[i],combolist[i])
mygroupbox.setLayout(myform)
scroll = QtWidgets.QScrollArea()
scroll.setWidget(mygroupbox)
scroll.setWidgetResizable(True)
scroll.setFixedHeight(200)
layout = QtWidgets.QVBoxLayout(self)
layout.addWidget(scroll)
if __name__ == '__main__':
app = QtWidgets.QApplication(['Test'])
window = Window(12)
window.setGeometry(500, 300, 300, 200)
window.show()
app.exec_()
PyQt4
from PyQt4 import QtGui
class Window(QtGui.QWidget):
def __init__(self, val):
QtGui.QWidget.__init__(self)
mygroupbox = QtGui.QGroupBox('this is my groupbox')
myform = QtGui.QFormLayout()
labellist = []
combolist = []
for i in range(val):
labellist.append(QtGui.QLabel('mylabel'))
combolist.append(QtGui.QComboBox())
myform.addRow(labellist[i],combolist[i])
mygroupbox.setLayout(myform)
scroll = QtGui.QScrollArea()
scroll.setWidget(mygroupbox)
scroll.setWidgetResizable(True)
scroll.setFixedHeight(200)
layout = QtGui.QVBoxLayout(self)
layout.addWidget(scroll)
if __name__ == '__main__':
app = QtGui.QApplication(['Test'])
window = Window(12)
window.setGeometry(500, 300, 300, 200)
window.show()
app.exec_()
