Popover constrain API is not exposed

[Susurrus]

The Popover class is missing set/get_constrain_to and the related PopoverConstraint. This code is commented out in the gir-generated files, but I'm not certain why. But re-running Gir locally within this repo doesn't regenerate any code for versions newer than 3.12. Is this because the Gtk.gir file needs to be updated for the Popover class?

[EPashkin]

In line //fn get_constrain_to(&self) -> /*Ignored*/PopoverConstraint; /*Ignored*/ means that PopoverConstraint don't generated. Normally you need add "Gtk.PopoverConstraint", to generate = [ array in config.
Don't understand why you don't get 3.14++ versions by generate (may be your installed gtk too old)?

[Susurrus]

Okay, I added the missing type. I definitely have Gtk3.20 on this machine (Runing Fedora 25). Do you know how Gir decides what version to generate for? I don't know where I'd even check what version it's trying to generate files for.

[EPashkin]

If I don't forgot anything, for gir just uses .gir files and add all versions from it.

[Susurrus]

When running make gir after adding the PopoverConstraint type to Gir.toml I got WARN:gir::config::gobjects: Configured object Gtk.PopoverConstraint missing from the library. But I don't actually understand what that means. In the Gtk-3.0.gir file the PopoverConstraint value is defined there.

@Susurrus, can you clone gtk to new place and do make in it? May be your gir \ gir-files submodules gone wrong.

[Susurrus]

Indeed, a git clean in the submodules and a submodule update fixed things. See the PR I just made that fixes this. Thanks for your help!

I'm closing this in light of #427.
