I'm trying to get a GTK-3.0-based app to build and I need to modify some code so that it uses the "master" property in a struct:
https://developer.gnome.org/gdl/stable/GdlDockLayout.html#gdl-dock-layout-new
I have little experience programming with GTK, so I don't know how to access these properties. And unfortunately "property" is such an overloaded term that Google yields nothing useful.
