好的，我真的需要帮助...我有一个dockwidget，在那个dockwidget我有一个textedit。好的，到目前为止一切都很好，以下是代码：

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _fromUtf8(s):
        return s

try:
    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig)

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName(_fromUtf8("MainWindow"))
        MainWindow.resize(320, 240)
        self.centralwidget = QtGui.QWidget(MainWindow)
        self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
        MainWindow.setCentralWidget(self.centralwidget)
        self.dockWidget = QtGui.QDockWidget(MainWindow)
        self.dockWidget.setFeatures(QtGui.QDockWidget.NoDockWidgetFeatures)
        self.dockWidget.setObjectName(_fromUtf8("dockWidget"))

        self.textEdit = QtGui.QTextEdit()
        self.textEdit.setGeometry(QtCore.QRect(40, 10, 104, 71))
        self.textEdit.setObjectName(_fromUtf8("textEdit"))
        self.dockWidget.setWidget(self.textEdit)

        MainWindow.addDockWidget(QtCore.Qt.DockWidgetArea(8), self.dockWidget)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None))

if __name__ == "__main__":
   import sys
   app = QtGui.QApplication(sys.argv)
   Form = QtGui.QMainWindow()
   f = Ui_MainWindow()
   f.setupUi(Form)
   Form.show()
   sys.exit(app.exec_())

现在，我想要做的是在窗口（或dockwidget）的底部放置一个行编辑，它与文本区域重叠，在调整dockwidget大小时不会移动，并填充整个dockwidget。我试过这个：

但这不是我想要的。我真的需要让这个工作，所以任何帮助都会很棒。谢谢。

以下是如何在另一个之上显示小部件的示例：

class MyWindow(QtGui.QWidget):
    def __init__(self, parent=None):
        super(MyWindow, self).__init__(parent)

        self.pushButtonInput = QtGui.QPushButton(self)
        self.pushButtonInput.setText("Toggle the QLineEdit widget!")
        self.pushButtonInput.clicked.connect(self.on_pushButtonInput_clicked)

        self.textEditInput = QtGui.QTextEdit(self)
        self.textEditInput.setText("This is a QTextEdit widget.")
        self.textEditInput.installEventFilter(self)

        self.lineEditInput = QtGui.QLineEdit(self)
        self.lineEditInput.setText("This is a QLineEdit widget.")
        self.lineEditInput.hide()

        self.layoutVertical = QtGui.QVBoxLayout(self)
        self.layoutVertical.addWidget(self.pushButtonInput)

    app = QtGui.QApplication(sys.argv)
    app.setApplicationName('MyWindow')

    main = MyWindow()
    main.show()

    sys.exit(app.exec_())

PyQT：LineEdit超过QTextEdit
