Question

我正在尝试制作我的第一个python应用程序。我想制作简单的电子邮件发件人表格在qt designer中创建一个dialog.ui，然后从dialog.ui生成dialog.py 并写下函数

def SendEmail(self,efrom,eto,esubj,ebody):
    msg = MIMEText( ebody.encode('UTF-8'),'html', 'UTF-8')
    msg['Subject'] = esubj
    msg['From'] = efrom
    msg['To'] = eto
    s = smtplib.SMTP()
    s.connect("mail.driversoft.net", 25)
    s.login("info@mysite.net", "1234567")
    s.sendmail(efrom, [eto], msg.as_string())
    s.quit()

并尝试连接到插槽

QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL("clicked()"), self.SendEmail("info@mysite.net", "test@mysite.net", "subject", "bodytext"))

当我尝试启动此应用时，我没有在电子邮件复原消息和控制台中看到表单

Traceback (most recent call last):
File "C:\Documents and Settings\a.ivanov\My Documents\Aptana Studio Workspace\test1\src\wxtest.py", line 61, in <module>
ui.setupUi(Dialog)
File "C:\Documents and Settings\a.ivanov\My Documents\Aptana Studio Workspace\test1\src\wxtest.py", line 33, in setupUi
QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL("clicked()"), self.SendEmail("info@mysqite.net", "test@mysite.net", "subject", "bodytext"))
TypeError: arguments did not match any overloaded call:
QObject.connect(QObject, SIGNAL(), QObject, SLOT(), Qt.ConnectionType=Qt.AutoConnection): argument 3 has unexpected type 'NoneType'
QObject.connect(QObject, SIGNAL(), callable, Qt.ConnectionType=Qt.AutoConnection): argument 3 has unexpected type 'NoneType'
QObject.connect(QObject, SIGNAL(), SLOT(), Qt.ConnectionType=Qt.AutoConnection): argument 2 has unexpected type 'bytes'

我怎么办表格我写主题和文字然后按发送按钮并通过电子邮件收到消息？谢谢！

QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL("clicked()"), self.SendEmail("info@mysite.net", "test@mysite.net", "subject", "bodytext"))

SIGNAL-SLOT系统的工作原理并非如此。你的信号“clicked（）”没有参数 - 所以你的插槽也必须没有参数。并且您必须传递对回调的引用，而不是在连接中调用该函数。

QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL("clicked()"), self.pushButtonClicked)

def pushButtonClicked(self):
    self.SendEmail("info@mysite.net", "test@mysite.net", "subject", "bodytext")
