Hello,<br><br>I&#39;ve been trying to write my first Plasmoid in python, and I&#39;ve been stuck on using the DataEngines [1].  I&#39;m working off of the microblog applet [2] to try and understand how to interact with that engine.  My problem comes when I try to get a service from my engine.  I&#39;m getting an error:<span style="font-family: courier new,monospace;"> <b>AttributeError: &#39;DataEngine&#39; object has no attribute &#39;serviceForSource&#39;</b></span> even though the api says it should be there [3]<br>
<br>Here is the chunk that is erroring out on me:<br><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">  self.engine = self.dataEngine(&quot;microblog&quot;)</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">  if not self.engine.isValid:</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">    self.setFailedToLaunch(True, &quot;Could not get DataEngine&quot;)</span><br>
<span style="font-family: courier new,monospace;">  service = self.engine.serviceForSource(&quot;Timeline:Jmhobbs@<a href="https://twitter.com/">https://twitter.com/</a>&quot;)</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">  cg = service.operationDescription(&quot;auth&quot;);</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">  cg.writeEntry(&quot;password&quot;, &quot;SuperSecret&quot;);</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">  service.startOperationCall(cg);</span><br><br>I&#39;m running  Python 2.5.4, and KDE - 4.2.4  (Debian sid)<br><br>My questions are,<br><ol><li>Is there something fundamentally wrong with my understanding on how to use DataEngines?</li>
<li>Is there just a version mismatch between the bindings (as documented) and my system?</li><li>Is there documentation on the microblog engine and how to use it?</li><li>Do I have an alternative? I tried QThreads/urllib (crashes unpredictably), and KIO (KUrl seems to ignore setUser() and setPass()) already to no avail.<br>
</li></ol>Thanks so much in advance for your assistance.  I&#39;m looking forward to creating more community content once I iron this stuff out :-)<br><blockquote style="margin: 1.5em 0pt;"></blockquote>[1] - <a href="http://techbase.kde.org/Development/Tutorials/Plasma/Python/Using_DataEngines">http://techbase.kde.org/Development/Tutorials/Plasma/Python/Using_DataEngines</a><br>
