python - Pyqt4年龄计算器不在标签上输出

问题描述

我的 python/QT (Pyqt4) 程序应该在按下计算按钮后输出一个人的年龄，但它没有，我哪里出错了。特此附上我的代码和程序运行时的截图。我的 python 代码不显示标签中的文本。

这是我的 .pyw 文件

import sys
from ass2q2 import *

class MyForm(QtGui.QDialog):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)
        QtCore.QObject.connect(self.ui.calculateBtn, QtCore.SIGNAL('clicked()'),self.dispmessage)

    def dispmessage(self):
        bd=(self.ui.calBD.selectedDate())
        curr= QDate.currentDate()
        yourAge = bd.daysTo(curr)        
        self.ui.labelOutput.setText("Your Age (in days) is: " +yourAge.toString())


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = MyForm()
    myapp.show()
    sys.exit(app.exec_())
