How to connect signals with builder?

[diamondburned]

I'm not sure; I'm not very familiar with the Builder API. Perhaps you'd want to grab each object and attach a signal to them manually?

There is an internal mechanism to allow storing Go data inside any GObject, which can be useful here, but it's not exposed at the moment. If that eases using Builder, I can consider exposing it for the user.

Yes, manual connecting works.

Like

obj := builder.GetObject("about_button")
obj.Connect("clicked", onAboutButtonClicked)

But it's not as nice as if I can see the handler in the xml file.

I found something about this topic in gnome forum: https://discourse.gnome.org/t/gtk-4-how-to-replace-gtk-builder-connect-signals/3561/3
It says that the language binding needs to implement GtkBuilderScope interface in an ancillary object. (And also some detailed info.)
Does that mean anything to you?

gotk4 doesn't have the right code to create custom objects that implement GLib
interfaces yet, so that won't work.

GLib interfaces are horribly painful to implement without the caked-up C macro
monstrosity, so it might take me at least half a year of fiddling around before
I can even get a working prototype.

OK I understand, it's a lot of work.
So it's out of scope now - it's ok!

Thank you for checking!

I'm reposting this comment that I accidentally made on gotk3/gotk3, thinking
it's gotk4:

This seems valid. If you ever want to PR this directly into the library, you can open one for adding a new function NewSignal in pkg/core/glib.
