The problem is not that the project change, it's that there are many
projects open at the same time and I need to be able to tell which one the
plasmoid is targeting.
I thought I could use that data engine approach but looks like that all
projects would have to share the same DataEngine instance so I still need to
tell them separately what project do they have to target somehow.

</div>here's an example of how you could create an engine that knows when the<br>
project changes:<br>
<br>
QWeakPointer<MyDataEngine *> m_engine;<br>
<br>
DataEngine *MyPluginLoader::loadDataEngine(const QString &name)<br>
{<br>
if (name == "org.kde.kdevelop.project") {<br>
m_engine = new MyDataEngine;<br>
connect(m_projectManager, \
SIGNAL(projectChanged(QString)),<br> m_engine.data(),<br>
SLOT(projectChanged(QString)));<br>
return m_engine.data();<br>
}<br>
<br>
return 0;<br>
}<br>
<br>
remember that DataEngineManager will delete the engine when it is no longer<br>
used, so be sure to use a QWeakPointer.<br>
<br>
similar approaches to the above should give you all the flexibility needed.<br>
