How to find replacements for deprecated functions

[Erik de Castro Lopo <mle+gtk mega-nerd com>]

HI all,

I am an occassional GTK user, and often I work on resurrecting code
bases for which I am not the original author. As such I often run
into reprecation warnings. When I go to the documentation I find
things like this:

    https://developer.gnome.org/gtk3/stable/GtkUIManager.html#gtk-ui-manager-get-widget

    "gtk_ui_manager_get_widget has been deprecated since version 
     3.10 and should not be used in newly-written code."

How is someone like me supposed to figure out what to replace that
function with in the code I'm hacking on?

Erik
