| nik90 | ahayzen, Hi | 18:24 |
| ahayzen | nik90, o/ | 18:24 |
| nik90 | ahayzen, where do I find online docs on MediaPlayer Playlist property? | 18:25 |
| ahayzen | in the music-app :') | 18:25 |
| nik90 | I looked at Qt Multimedia 5.5 MediaPlayer QML, and I couldn't find that property | 18:25 |
| ahayzen | it is 5.6 | 18:25 |
| nik90 | ah | 18:25 |
| nik90 | okay, so I will store my queue in localstorage and then pass that model to playlist and manage currentIndex and so on.. | 18:26 |
| ahayzen | nik90, although something like this looks close .. https://developer.ubuntu.com/api/apps/qml/sdk-15.04.1/QtMultimedia.Playlist/ | 18:26 |
| ahayzen | nik90, just copy what we do until save() works | 18:26 |
| nik90 | In your implementation, since you guys have Shuffle and Repeat modes, it is increasing the complexity of your implementation. | 18:26 |
| ahayzen | not for this bit.. | 18:26 |
| ahayzen | nik90, you need the saveQueue() method http://bazaar.launchpad.net/~music-app-dev/music-app/trunk/view/head:/app/components/Player.qml#L253 | 18:27 |
| ahayzen | nik90, then just add saveQueue() to onItem{Changed,Inserted,Removed} http://bazaar.launchpad.net/~music-app-dev/music-app/trunk/view/head:/app/components/Player.qml#L157 | 18:27 |
| nik90 | ahayzen, what's the need for pendingCurrentIndex? Do I need it as well? | 18:28 |
| ahayzen | that stuff is because addItem(s) is async | 18:28 |
| nik90 | Can't I just check the currentIndex position and use that to check if there are more items in the playlist to be played? | 18:28 |
| nik90 | hmm | 18:28 |
| ahayzen | so to get the setting of the currentIndex done at the correct time it has to be done *after* the first item is actually added etc | 18:28 |
| nik90 | ok | 18:29 |
| ahayzen | nik90, if you want to store the currentIndex ... | 18:29 |
| ahayzen | nik90, that is done here http://bazaar.launchpad.net/~music-app-dev/music-app/trunk/view/head:/app/music-app.qml#L59 | 18:30 |
| ahayzen | nik90, all the pendingCurrentIndex stuff is only for trackClicked() to work correctly | 18:30 |
| nik90 | ok | 18:31 |
| ahayzen | as you can't, or when we developed it you couldn't, set the index before adding the items up to that | 18:31 |
| ahayzen | so if you had currentIndex=5 ... you couldn't set that until there were 5 items in the queue | 18:31 |
| ahayzen | and as addItem(s) is async, you have to wait for the signal to be fired | 18:31 |
| nik90 | ah ok.. | 18:32 |
| ahayzen | if that makes sense ? | 18:32 |
| ahayzen | you probably won't notice it on small queue sizes | 18:32 |
| nik90 | Where do you guys check for the fired signal? | 18:32 |
| ahayzen | but when we got onto testing 100s of songs, without it weird stuff started happening | 18:32 |
| nik90 | yeah our queues should be much smaller | 18:32 |
| nik90 | I see processPendingCurrentState() | 18:33 |
| ahayzen | nik90, that is the onItemInserted .. http://bazaar.launchpad.net/~music-app-dev/music-app/trunk/view/head:/app/components/Player.qml#L137 | 18:33 |
| nik90 | ok, I think I have a basic idea of how this works. I will get a start on this for Podbird. Wish me luck :P | 18:33 |
| ahayzen | nik90, can you not just directly copy our Player.qml ? | 18:34 |
| ahayzen | or at least the Playlists part of it | 18:34 |
| nik90 | I will copy the Playlists part of it since we do some stuff in our MediaPlayer implementation already that I need to integrate it with. | 18:35 |
| ahayzen | yeah if you copy that part, at least you know everything should 'work' :-) | 18:35 |
| nik90 | yes | 18:36 |
| nik90 | thnx for the help. this should help me get started. | 18:37 |
| ahayzen | no problem, ping me if you need any extra help | 18:43 |
| danialbehzadi | Hi there. | 22:19 |
| danialbehzadi | When I click on the "Run" button in Qt creator, it just says "No executable specified.", But I can run the qml file with "$ qmlscene Main.qml" in terminal. What's the problem? | 22:19 |
