This prevents any sort of error handling because this method returns too early.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Testing that invokeMethod worked is only half the story. If the QueuedConnection can be removed, you can use a return argument of type bool for error handling?
Or better, a KIO error code, so we can give the exact error message (I see that we didn't have "directory not empty" for rmdir, but if this is extended to other actions then it will be useful to have).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In fact, instead of invokeMethod this could be a set of if(method == "...")? Seems simpler to me, but I have no strong opinion.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch intends to demonstrate one possible approach to provide polkit support in kio. Here its only for the delete operation. This is based on the patch in task https://phabricator.kde.org/T5070.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The approach is as follows;
1. Whenever file ioslave gets access denied error it calls the method <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">execWithRoot</em> with the action that requires priviledge, the path of items
upon which action needs to be performed and a warning ID as arguments.
2. <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">execWithRoot</em> then executes the KAuth::Action <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">org.kde.kio.file.execute</em>.
3. This Kauth::Action has its Persistence set too 'session'. This means that after authentication the restrictions are dropped for a while, for <br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
about 5 minutes. This is similar to the behaviour of sudo command.
4. During this time we can perform any action as a privileged user without any authentication. So to prevent any mishap i added a warning box which
would popup before performing any action(only during this period).
5. After the said time interval the root privileges are droped and calling <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">execWithRoot</em> should show the usual authentication dialog.</p></pre>
