@rbuj I hope my fix is OK?

It's because of cherry-picking the commit https://github.com/mate-desktop/mate-power-manager/commit/d879a18a09e9cbdd43050365e08afd9f9bee72bd to 1.24 brach.

There is no GET_WIDGET macro on 1.24 branch:

https://github.com/mate-desktop/mate-power-manager/blob/50df11895cba8aac8f0d0bd52b97c835a2a4afc0/src/gpm-prefs-core.c#L43

just add the macro as follows:

 struct GpmPrefsPrivate

Yes, i saw the commit where you added #define GET_WIDGET(x) (GTK_WIDGET (gtk_builder_get_object (prefs->priv->builder, (x))))

So i think my fix is OK?
