python Qt4 Comment lier l'action sur le bouton cliquez sur

Question

J'essaie de faire ma première application python. Je veux faire un simple formulaire d'expéditeur d'email. Dans concepteur qt créer un dialog.ui, puis générer dialog.py de dialog.ui et écrire il fonctionne

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() 

et essayez connecter à l'emplacement

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

lorsque je tente commencer cette application , je ne vois pas une forme, sur mon e-mail un message relancer, et dans la console

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)

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

Il est comment le système fonctionne SIGNAL-SLOT. Votre signal "clicked()" n'a pas de paramètres - donc votre slot ne doit pas avoir de paramètres. Et vous devez passer une référence à callback, ne pas appeler cette fonction dans connect.

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

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