Is it actually an issue (since the constructor should operate in the GUI thread)?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I commented this out to see if it resulted in any difference in function with Qt5; I didn't notice any difference, but did mean to comment it back in as I did not do a full examination of the code behind the scenes. I've put this line back in here locally.</pre>

We get the root window without having called qApp->desktop(). Quite sure about it, because I migrated QX11Info::appRootWindow() away from doing exactly what this line of code was doing.</pre>

When I tested without that line, everything seemed to work exactly as expected. I just didn't have time to delve into the code further to confirm the anecdotal evidence ;)
So... can I push? :)</pre>

This is due to NETEventFilter being a QWidget. This patch addresses the issue by using a QObject to create the NETEventFilter, which is itself first moved to the main application thread. </pre>
