<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">But in fact I wonder if it should really be a member variable. Can the Helper be reused for more than one action? In that case the error from one operation will pollute the next one.</p>

<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>
