GNOME Bugzilla – Bug 705488
API to indicate tab has new information
Last modified: 2018-05-02 15:45:00 UTC
Some uses of notebook tabs need a way to indicate the page has new information for the user. For instance, web browsers sometimes use color to indicate a page has a new notification or updates.
Isn't this a bit too specific for GTK+ to handle, and something the app dev should implement themselves?
Huh, maybe not; there is a :needs-attention child property on GtkStackSwitcher, which indicates a corresponding thing may be considered valid for GtkNotebook. https://developer.gnome.org/gtk3/stable/GtkStack.html#GtkStack--c-needs-attention
