gtk3 Volume Control for tint2

[misko_2083]

My attempt to make a volume control context menu that launches from tint2.
Uses amixer
It wasn't showing properly untill I've installed libgtk-3-0
Here is the launcher =>
/usr/local/bin/tint2launchers/07-sound.desktop

The script closes when clicked outside of the menu.
There is a mute switch but will work as a button also.

This is really cool misko_2083

I am going to play with this and get it to work on the top right tint2 and make it a default in VSIDO if that is all right with you

Well done mate, good solid work!

[zephyr]

@misko_2083: Dang, works very well and easy to configure. Great addition, thanks - z

[VastOne]

@ misko_2083

You should let everyone know in your first post that the menu.py file must be made executable... 

Most know this or would figure it out, but having it there will save a step for you and for them...

Thanks

[VastOne]

Here it is in the Panel Tint2 on VSIDO

Cool. Thank you. I'm not using tint2 currently, but this one goes directly to the goodies stash.

Sure, I'm Ok with that VSIDO get's a Volume control.

If they are launching with python3 there is no need.

That's cool. Minimalistic approach but sometimes it takes some time to launch. It's faster if it stays in the memory. I'll post in the next comment, it probably won't fit in this one. 

Cool. Thank you. I'm not using tint2 currently, but this one goes directly to the goodies stash.

Welcome.

[misko_2083]

@VastOne I've been playing with this and made a lot of changes. Script makes an icon in the tray area, while it's in the memory the icon will be there.
Launches faster.
There is a right and left click menu now. Left click menu is the same except the label is added.
Right-click menu can launch PulseAudio Volume Control, Alsamixer and About dialog. Also there is a Quit option.

Incredible... These are the exact enhancements I was going to recommend to you

That is fantastic, thank you for this. This will be a standard on the next ISO's I build

Great work!

[PackRat]

about this line:

Code Select Expand

vsido_icon = "//usr/local/bin/images/vsidoorb_blk_sm_140.png"

is "//usr" a typo, or does the "//" mean something in python3?

[VastOne]

Good catch PackRat... the line just below that also has one where:

Code Select Expand

notification_icon="/usr/share/icons/LinuxLex-8/status/24/notification-audio-volume-high.png"

has no spacing after the icon= area here

notification_icon="/usr/share/icons/LinuxLex-8/status/24/notification-audio-volume-high.png"

should be

notification_icon = "/usr/share/icons/LinuxLex-8/status/24/notification-audio-volume-high.png"

... but I ran the code with the errors and without and the code works just the same

Ah, it was a typo. 
Nice catch @PackRat
It's working because UNC paths can be used. Those are used when accessing directories and files on a network, but works on local files too.
It should be like this:

@VastOne Python doesn't care about spaces just the indent. Though it looks better if it's properly formated.

Not sure what the cause is, I searched for a solution but came up empty ... It works flawlessly on this machine which leads me to believe there is a dependency this machine has met but the build environment does not have

I have a new install of this ready for any testing ... Let me know what is needed

That was it... that brought in several more dependencies but we can live with their size
