Thanks for great player app.

Should pebble volume control work as well? For me peblled just logs error:
ERROR WatchCommands - "Property org.mpris.MediaPlayer2.Player.Volume is read-only"

No that doesnt work yet. I have yet to figure out how to influence the system volume on the jolla via an app. But once I do I will implement those functions properly and do some other cool stuff as well.

D-Bus interface hey, sounds like a good target for little library and blog post, unless someone has already done so?

Re: [WiP] SirenSong v0.3 - Music Player for SailfishOS

The point of dbus is that you can talk to programs with any language (able to send dbus message), without nailing your app to a specific library.

Re: [WiP] SirenSong v0.3 - Music Player for SailfishOS

Which makes perfect sense from a systems perspective. but from an encapsulation and code reuse perspective writing a cpp library that handles the interface makes sense.

of course you can write your own, but for most people they're going to want some object that has the current volume, volup and voldown methods.

Re: [WiP] SirenSong v0.3 - Music Player for SailfishOS

Every good D-Bus access library (Qt included) automates wrapping D-Bus objects to library objects. D-Bus was modelled after KDE kbus to enable exactly this ease of use.
You just create QDBusInterface object wrapping /com/meego/mainvolume2 d-bus object com.Meego.MainVolume2 interface - and bam!, you have a local object to fiddle with its properties, sending signals - all with D-Bus messages working quietly in background.
No additional library needed.

Well there you go, learnt something new. Thanks Smoku

I tried it and I got:

Re: [WiP] SirenSong v0.3 - Music Player for SailfishOS

Believe it or not smoku that actually looks fine.

you can watch the progress using tracker-control
