Re: [Libreoffice-commits] Adapt SwSrcEditWindow's SyntaxTimerHdl to being used in an Idle now

So yeah SetTimeout should be deletet, but it should be replaced with
SetPriority (and of course set with an appropriate Priority), because
otherwise it gets the default priority: HIGH.

The taks should be stopped if there is absolutely no more work to do. If
stop is called it gets completely removed of the tasklist. So if you think
that it has no more work todo you can stop it by yourself.

But i think i get your point, because i see that i missed to ask if the
task is active (i only check if it should be delete). I wil change this and
then you could set the task as inactive if you think that for now it has no
more work to do and if it comes to the position:


  if (... !pIdle->IsActive()) pIdle->Start();

it should be reactivatet.
