How should icons be set for Appindicators? Can unique icons be used or should window manager icons be used?
On the appindicator dev page, it states:
It seems from this, that programs should use standard icons. What are the icons that can be used?
The icons need to use icon names from themes, direct paths to icon files are not supported. For example, icon names used with gtk_status_icon_new_from_file() won’t work.
From the example code:
Where is "indicator-messages-new" defined?
app_indicator_set_attention_icon (indicator, "indicator-messages-new");
