Question

def run(self):
        """Run method that performs all the real work"""
        # show the dialog
        self.dlg.show()
        # Run the dialog event loop
        x = self.dlg.lineEdit.text()
        y = self.dlg.lineEdit_2.text()
        z = int(x)+int(y)
        result = self.dlg.exec_()
        # See if OK was pressed
            # Do something useful here - delete the line containing pass and
            # substitute with your code.
        QMessageBox.information(self.iface.mainWindow(),"sum is =", "%d" %z)

但它显示了z=int(x)+int(y).x中的ValueError，y来自x的行编辑box..type，y是unicode…我应该如何将x和y相加？

定义运行(自身)：

    """Run method that performs all the real work"""
    # show the dialog
    self.dlg.show()
    self.dlg.spinBox.clear()
    self.dlg.spinBox_2.clear()

    # Run the dialog event loop


    result = self.dlg.exec_()
    if result:
        x = self.dlg.spinBox.value()
        y = self.dlg.spinBox_2.value()
        z = x+y
    # See if OK was pressed
        # Do something useful here - delete the line containing pass and
        # substitute with your code.
        QMessageBox.information(self.iface.mainWindow(),"sum is =","%d" %z)
