python Qt4 How to bind action on button click
<p>I'm trying make my first python app. I want make simple email sender form.
In qt designer create a dialog.ui, then generate dialog.py from dialog.ui
and write there function</p>

<pre><code>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()
</code></pre>

<p>and try connect to the slot</p>

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

<p>when I try start this app, I don't see a form, on my email revive message, and in console</p>

<pre><code>Traceback (most recent call last):
File "C:\Documents and Settings\a.ivanov\My Documents\Aptana Studio Workspace\test1\src\wxtest.py", line 61, in &lt;module&gt;
