Alright, I have hacked away and continued the GTK3 conversion - It was
way more work than I anticipated, but an initial version is buildable
(Nowhere near release quality yet though).
It is not finished, but it is good enough to get an impression of what
a GTK3 version would look like.
I have moved the images from the pixmaps folder to the src folder, and
include them in a gresource file. (This is the modern way to build
resources to C code, so you don't have to load it from disk by hand and
have the resources loaded from file on program start, they are included
in the compiled binary - it's the more modern way of what was done with
xpm images, and can include all resources, not just images).
All menus and toolbars needed to be converted to this new way, and
menus in GTK3 cannot contain images, so that is a change. Toolbars can,
and I have used toolbars, but the toolbar widget is being removed in
GTK4, and should be replaced with a GtkBox with the proper layout and
settings. I have stayed with the standard GtkToolbar for now.
I think I have changed the places needed, but I haven't fully connected
all signals yet, and there are surely places where I have done mistakes
or simply not come to yet, there is still more work to be done, but you can
build and test the program with your current GTK3 theme. (One theme I
have tested I didn't get separators in the toolbar, but that is
theme-specific, using the Elementary theme all looks really nice).
All can be found at https://github.com/gusnan/gpa , and
pull-requests and suggestions would be greatly appreciated.
