I wasn't confused about the deprecation model. My question was more
about what the consequence of the eventual removal might be. How would
an application go about getting the same effect at GtkAlignment without
using it directly? Again assuming values for scale and alignment that
are fractional.

The proper way would be to use their own custom widget for that.

If the licensing terms allow it, you could even copy-paste
GtkAlignment in your project.

Alternatively, you bundle your own version of GTK+ and never update
it; or you never update to GTK+ 4.0 until you decide to redesign your

As I said, I personally think that using fractional alignments is
wrong and just a way to get around the fact that using pixel-precise
positioning is not something GTK recommends. When we implemented the
alignment properties for GtkWidget before releasing 3.0 we looked at
what people were using in open source projects, and we found that the
vast majority were using 0, 0.5, and 1.0 as alignment values — and the
few people that required different alignments were better served by
padding, margin, and spacing dependent on font size, not on fractions
of the parent widget's size.
