PyQT：通過QTextEdit進行LineEdit

Question

好的，我真的需要幫助……我有一個dockwidget，在那個dockwidget中，我有一個textedit。 好的，到目前為止一切都很好，這是代碼：

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_())

現在，我想做的是在窗口（或dockwidget）的底部放置一個行編輯，該行與文本區域重疊，在調整dockwidget的大小時不會移動，並填滿整個dockwidget。 我已經試過了：

        self.dockWidget.setWidget(self.textEdit)

        QtGui.QLineEdit(self.dockWidget)  # Line edit

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

   Form.show()
   sys.exit(app.exec_())

但這不是我想要的。 我真的需要使此工作正常進行，因此任何幫助都將非常有用。 謝謝。

這是一個如何在另一個窗口小部件上顯示窗口小部件的示例：
