I have installed GNOME Builder 42.1 version from Flathub. Also Glade 3.38 version from flathub too.
I’m trying to develop a GTK4 Vala GNOME application, but if I edit the .ui file with Builder’s internal “Glade”, it adds
<packing> tags, then the compilation is not working.
I’m using GtkTemplate to use .ui file inside .vala
I just checked the docs and I couldn’t find a method like “set_center_widget” in GTK3. I want a center widget in a Gtk.Box.
- How do I set a center widget in GTK4?
- How do I prevent the “internal Glade” of GNOME Builder is corrupting the .ui file?
- If I must write the .ui by hand, any tutorial for that or GTK4 xml reference?
