margin documentation

[Igor Korot <ikorot01 gmail com>]

Hi,
In the https://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget--margin-xxx
it says :

[quote]
Allowed values: [0,32767]
[/quote]

However, it does not explain which value correspond to what alignment.

Does 0 mean the widget should be expanded to fill the space allocated
or its used to be a minimal
allocated size?

Thank you.
