[SailfishDevel] QML Timer stops running

to avoid trial and error with Harbour for you: I don’t think you will make it into Harbour with this Audio Workaround :-(

This is a part of my last rejection reason:

“It seems that there are problems in audio usage. […] Also audio usage is blocking suspend when I press Power button .”

In my case there were a few Audio elements in my app that blocked suspend mode, allthough they had finished running or were paused. And at least in my case it seems to be a bug in Sailfishs QtMultimedia implementation that will (I hope so) get fixed some day.

So, I switched my shutdown logic to qml timers and they work just fine when the gstreamer pipeline is in paused state. And I got a bit curious so I also tested with the qml multimedia plugin and it worked just fine too. So basically all you need is one line (and one import) to make timers work in qml:

Audio { source: "file.mp3" }

That's it. I don't know which way is the best but I know which is the laziest. Just throw in a few cool sounds to complement the obnoxious beeper. :)

That's an interesting approach :) I just might try that if it doesn't pass QA.
