Hi, I try to upgrade the user interface files of my package galvani (https://salsa.debian.org/science-team/galvani)from gtk3 to gtk4. I used glade so far to build the user interface and I made an attempt to convert the XML files by using gtk4-builder-tool with command simplify and options --3to4 and --replace. But the output is just garbage. Has anyone the same problem and found a good solution? Best regards Burkard
