What does "cb" stand for when using app_entries?

So I have been learning how to create GTK4 applications using Vala, I’m adding a little about dialog and I noticed GNOME projects follow the same method naming when it comes to showing them.

For example, that method contains the _cb part, and I’m curious to know what it stands for, thanks. :smiley:

This is not standard naming, or a requirement. Typically, _cb just means “this function or method is invoked as a callback handler in response to a signal emission”.
