如何通過單擊Qt Designer中的按鈕來打印日期？

Question

我正在嘗試通過Qt設計器創建一個表單，該表單將由用戶頻繁更新。我想讓用戶選擇日期並保存該日期以跟蹤表單最後更新的時間。 The image is what my form currently looks like. If the user clicks the 'save date' button, the date selected just above will be saved.

我使用Python編程這一點，目前這是我的代碼如下所示：

from PyQt4 import QtCore, QtGui 
import sys 

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_Form(QtGui.QWidget): 
    def __init__(self): 
     QtGui.QWidget.__init__(self) 
     self.setupUi(self) 

    def setupUi(self, Form): 
     Form.setObjectName(_fromUtf8("Form")) 
     Form.resize(785, 596) 
     self.gridLayout = QtGui.QGridLayout(Form) 
     self.gridLayout.setObjectName(_fromUtf8("gridLayout")) 
     self.comboBox_2 = QtGui.QComboBox(Form) 
     self.comboBox_2.setObjectName(_fromUtf8("comboBox_2")) 
     self.gridLayout.addWidget(self.comboBox_2, 18, 0, 1, 1) 
     self.checkBox = QtGui.QCheckBox(Form) 
     self.checkBox.setObjectName(_fromUtf8("checkBox")) 
     self.gridLayout.addWidget(self.checkBox, 3, 0, 1, 1) 
     self.comboBox = QtGui.QComboBox(Form) 
     self.comboBox.setObjectName(_fromUtf8("comboBox")) 
     self.comboBox.addItem(_fromUtf8("")) 
     self.comboBox.addItem(_fromUtf8("")) 
     self.comboBox.addItem(_fromUtf8("")) 
     self.gridLayout.addWidget(self.comboBox, 19, 0, 1, 1) 
     self.lineEdit_3 = QtGui.QLineEdit(Form) 
     self.lineEdit_3.setObjectName(_fromUtf8("lineEdit_3")) 
     self.gridLayout.addWidget(self.lineEdit_3, 2, 0, 1, 1) 
     self.textBrowser_3 = QtGui.QTextBrowser(Form) 
     self.textBrowser_3.setObjectName(_fromUtf8("textBrowser_3")) 
     self.gridLayout.addWidget(self.textBrowser_3, 13, 0, 1, 2) 
     spacerItem = QtGui.QSpacerItem(20, 40, QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Expanding) 
     self.gridLayout.addItem(spacerItem, 4, 0, 1, 1) 
     self.lineEdit_2 = QtGui.QLineEdit(Form) 
     self.lineEdit_2.setObjectName(_fromUtf8("lineEdit_2")) 
     self.gridLayout.addWidget(self.lineEdit_2, 1, 0, 1, 1) 
     self.textBrowser_2 = QtGui.QTextBrowser(Form) 
     self.textBrowser_2.setObjectName(_fromUtf8("textBrowser_2")) 
     self.gridLayout.addWidget(self.textBrowser_2, 10, 0, 1, 2) 
     self.PrintDate_btn = QtGui.QPushButton(Form) 
     self.PrintDate_btn.setObjectName(_fromUtf8("PrintDate_btn")) 
     self.gridLayout.addWidget(self.PrintDate_btn, 16, 0, 1, 1) 
     self.textEdit = QtGui.QTextEdit(Form) 
     self.textEdit.setObjectName(_fromUtf8("textEdit")) 
     self.gridLayout.addWidget(self.textEdit, 7, 0, 1, 2) 
     self.lineEdit = QtGui.QLineEdit(Form) 
     self.lineEdit.setObjectName(_fromUtf8("lineEdit")) 
     self.gridLayout.addWidget(self.lineEdit, 0, 0, 1, 1) 
     spacerItem1 = QtGui.QSpacerItem(20, 40, QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Expanding) 
     self.gridLayout.addItem(spacerItem1, 8, 0, 1, 1) 
     spacerItem2 = QtGui.QSpacerItem(40, 20, QtGui.QSizePolicy.Expanding, QtGui.QSizePolicy.Minimum) 
     self.gridLayout.addItem(spacerItem2, 0, 1, 1, 1) 
     self.label = QtGui.QLabel(Form) 
     self.label.setObjectName(_fromUtf8("label")) 
     self.gridLayout.addWidget(self.label, 5, 0, 1, 1) 
     self.label_2 = QtGui.QLabel(Form) 
     self.label_2.setObjectName(_fromUtf8("label_2")) 
     self.gridLayout.addWidget(self.label_2, 9, 0, 1, 1) 
     self.label_3 = QtGui.QLabel(Form) 
     self.label_3.setObjectName(_fromUtf8("label_3")) 
     self.gridLayout.addWidget(self.label_3, 11, 0, 1, 1) 
     spacerItem3 = QtGui.QSpacerItem(20, 40, QtGui.QSizePolicy.Minimum, QtGui.QSizePolicy.Expanding) 
     self.gridLayout.addItem(spacerItem3, 12, 0, 1, 1) 
     self.dateEdit = QtGui.QDateEdit(Form) 
     self.dateEdit.setObjectName(_fromUtf8("dateEdit")) 
     self.gridLayout.addWidget(self.dateEdit, 14, 0, 1, 1) 


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

    def retranslateUi(self, Form): 
     Form.setWindowTitle(_translate("Form", "Enterprise Passport", None)) 
     self.checkBox.setText(_translate("Form", "1st Gen university", None)) 
     self.comboBox.setItemText(0, _translate("Form", "award1", None)) 
     self.comboBox.setItemText(1, _translate("Form", "award2", None)) 
     self.comboBox.setItemText(2, _translate("Form", "award3", None)) 
     self.PrintDate_btn.setText(_translate("Form", "SaveDate", None)) 
     self.label.setText(_translate("Form", "Activities", None)) 
     self.label_2.setText(_translate("Form", "Achievements", None)) 
     self.label_3.setText(_translate("Form", "Awards", None)) 
     self.PrintDate_btn.clicked.connect(self.PrintDate) 



    def PrintDate(self): 
     print(Ui_Form.setupUi(self.dateEdit)) 


if __name__ == '__main__': 
    app = QtGui.QApplication(sys.argv) 
    ex = Ui_Form() 
    ex.show() 
    sys.exit(app.exec_()) 

我已經嘗試了各種各樣的事情，但我似乎無法得到它的保存或甚至打印按下按鈕時所選的日期。有人能告訴我如何讓這個工作？

def PrintDate(self): 
     print self.dateEdit.text()
