}

The tray icon struct, describing the complete visual state.

Fields

volmeter: RefCell<Option<VolMeter>>

The volume meter to draw on the actual Pixbuf, if requested.

audio_pix: RefCell<AudioPix>

The actual Pixbuf tray icon.

status_icon: StatusIcon

The gtk StatusIcon widget, used to register callbacks.

icon_size: Cell<i32>

Methods

impl TrayIcon

fn new(prefs: &Prefs) -> Result<TrayIcon>

Constructor. audio_pix is initialized as empty GdkPixbuf, to save one iteration of png decoding (update_all() is triggered immediately on startup through tray_icon.connect_size_changed usually, otherwise we have to trigger it manually).

fn update_all(
    &self,
    prefs: &Prefs,
    audio: &Audio,
    m_size: Option<i32>
) -> Result<()>

Update the whole tray icon state.
