<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">sometimes you call this directly not via the Qt meta system. (i.e processHide)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">what calls processHide? could be the user pressing close, could be a timeout. If so the sender() will be that timer. It's the sender of the last signal we're processing, not the last method call made.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I suggest maybe </p>

Basically processQueues works as sort of dispatcher and processHide just returns the control back to it, it will then simply process next item in the queue. It's perfectly safe as processQueues is ever only called either manually (sender() == 0) or by the timer (sender() == QTimer). The lambda slot is maybe nicer, I just thought that it makes the code a bit harder to read...but I don't care that much.</p></pre>

This patch rewrites the notifications so that all actions such as show/reposition/hide are handled from a one single place and every action is properly queued and protected around, which makes it more robust, more predictive and less chaotic. There's also a slight delay between every action so it's also visually much more cleaner and easier to see what's going on. </p></pre>
