Question

我正在尝试通过Qt设计器创建一个表单，该表单将由用户经常更新。我想允许用户选择日期并保存该日期，以便跟踪表单上次更新的时间。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.

我正在使用python对此进行编程，目前这就是我的代码：

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_())

我已经尝试了各种各样的东西，但我似乎无法保存甚至打印按下按钮时选择的日期。有人可以告诉我如何才能让它发挥作用吗？

Answer 1

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

如何通过单击Qt Designer中的按钮来打印日期？
