This is currently in a working stage I'd say. More tests are required though, and some features are not yet implemented. These include:
And possibly more. For reference, these were the main sources of implementation: |
This runs JS constructors on objects that were not constructed from JavaScript. These are effectively objects constructed from GtkBuilder. This is done by tracking all objects currently being constructed in a variable named `ConstructContext`. If an object's `TypeInfo`'s `instance_init` method (see https://docs.gtk.org/gobject/struct.TypeInfo.html) while it's gType is not the currently being constructed type (i.e. the last element of `ConstructContext`), it is assumed that the object is being constructed from GtkBuilder and the object's constructor is called, but instead of creating a new `GObject`, the constructed object's `gi:ref` (pointer) is passed instead, and the javascript "construction" continues.
fixes cases like `error instanceof GLib.UriError`
A very good example is `GFile` as returned by `Gio.File.new_for_uri` which is an interface. However, since it's also an object, the unbox function will incorrectly set it to `GObject`.
I'm very sorry for this huge commit. It turns out I was working in an entirely different repo while I was waiting for other necessary PRs to get merged, and hence all the history was lost.

Warning
The current code is incomplete and won't run; it is awaiting merge from other dependency pull requests. I'll push all the code after the required branches have been merged (so I can test against the
mainbranch)This PR will include code that will allow the use of
GObject.registerClassin a fashion similar to what GJS already does.GObject.registerClassallows the following:GTypeFlags.GParamSpecsobj.connect("signal_name")It also allows higher integration with
