Hi all,
I'm trying to update from gtkmm-2.24 to gtkmm-3.18. As a dinosaur of a
previous age, I'm trying to move from manual menus to Gtk::Builder and
Gio::Resources. I've been through section 12 of the tutorial several
times, and have looked at the 3.18 source /demo/Makefile as a
reference. I'm using the example_builder.cc to learn how to load
resources int an app.
So far, the program compiles, but I'm getting a runtime error:
marty@builder$./x
main 0:
Error loading example_builder.ui: The resource at
'/builder/example_builder.ui' does not exist
I'm obvioysly mis-understanding something about resources, and would
appreciate any help you can provide. I've been stewing over this for
weeks.
Thanks,
Marty
