<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">And honestly I have no idea how one could get the information whether the window manager processed it in a reliable way. What might be the most reliable is to wait for the window being added to KWindowSystem::stackingOrder (there's a changed signal). It would give at least the hint that the window manager processed the window being shown.</p></pre>

It looks at kwindowsystem::activeWindow which indirectly comes from looking a property on the root window. KWindowsystem only updates changes from the root window system every event loop. So we can't use the value directly after we've opened our dialog.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Given we're calling forceWindowActive in policykitlistener when we show, so I don't actually need to see what the window manager has to say as I know we'll always be on top. To some extent we don't need this notification code at all, and I could just remove it.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">However, for the case that forceWindowActive doesn't work (such as running on Wayland) I left the code in.</p></pre>

It will also not (even less) guarantee that it's the top most window.</p></pre>
