Question

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，但事实并非如此，我哪里出错了。特此附上我的程序运行时的代码和屏幕截图。我的python代码未在标签中显示文本。

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_())

Pyqt4年龄计算器未在标签上输出
