从几个类一起构建Qt Gui

Question

下面是我的Gui的一个简短示例。我试图将Gui分成几个部分。InputAxis的元素应该与self具有相同的高度(水平分割)。收件人应该在他们的下面(垂直分割)。

在InputAxis我试图放置QLineEdit，但在我的Gui中我没有看到它。

import sys
from PySide import QtCore
from PySide import QtGui
class InputAxis(object):
    def __init__(self):
        self.frame = QtGui.QFrame()
        self.input_interface = QtGui.QLineEdit()
        self.form_layout = QtGui.QFormLayout()
    def genAxis(self):
        self.frame.setFrameShape(QtGui.QFrame.StyledPanel)
        self.form_layout.addRow('&Input:', self.input_interface)
        return self.frame
class Window(QtGui.QWidget):
    def __init__(self):
        QtGui.QWidget.__init__(self, parent = None)
        self.layout = QtGui.QVBoxLayout()
        self.form_layout = QtGui.QFormLayout()
        self.axes = list()
        self.axes.append(InputAxis())
        self.axes.append(InputAxis())
        self.splitter1 = QtGui.QSplitter(QtCore.Qt.Horizontal)
        for axis in self.axes:
            self.splitter1.addWidget(axis.genAxis())
        self.form_layout.addWidget(self.splitter1)
        self.setMinimumWidth(400)
        self.recipient = QtGui.QLineEdit(self)
        # Add it to the form layout with a label
        self.form_layout.addRow('&Recipient:', self.recipient)
        # Add the form layout to the main VBox layout
        self.layout.addLayout(self.form_layout, 0)
        # Set the VBox layout as the window's main layout
        self.setLayout(self.layout)
        QtGui.QApplication.setStyle( QtGui.QStyleFactory.create('Cleanlooks') )
    def run(self):
        self.show()
def main():
    qt_app = QtGui.QApplication(sys.argv)
    window = Window()
    window.run()
    sys.exit(qt_app.exec_())
if __name__=="__main__":
    main()

不工作的原因是这一行:

self.form_layout = QtGui.QFormLayout()

应该是:

self.form_layout = QtGui.QFormLayout(self.frame)
