Merge lp:~artem-anufrij/snap-elementary/Bugfix-1365978 into lp:snap-elementary

[Artem Anufrij]

Show a message when no camera detected

[Cody Garver (codygarver)]

Does not compile

review: Needs Fixing

[Cody Garver (codygarver)]

Also some code style violations, function() should be function ()

NoCamera.vala added

[Artem Anufrij (artem-anufrij)]

Hey Gody,

sorry, I forgot to add "NoCamera.vala".

[Corentin Noël (tintou)]

You don't need to translate the second argument in stack.add_named, the name is internal to Gtk and is used to identify the widget

[Artem Anufrij (artem-anufrij)]

Hey Cody,
"Gallery" and "Camera" are translated, too. Should I fixed them?

"
78. this.stack.add_named (this.gallery, _("Gallery"));
79. this.stack.add_named (this.camera, _("Camera"));
"

[Artem Anufrij (artem-anufrij)]

Sorry. I mean Corentin.

[Corentin Noël (tintou)]

Yes, please fix it

Second argument in 'stack.add_named' will not be translated.

[Artem Anufrij (artem-anufrij)]

done

[Cody Garver (codygarver)]

Code style is still wrong

Also the copyright should be attributed to something like "elementary Developers", not Mario

262. By artem-anufrij on 2014-10-03

License text was changed. Code style was corrected.

263. By artem-anufrij on 2014-10-03

Code style was corrected.

[Cody Garver (codygarver)]

The warning could look better but design team can deal with that later
