mattiasb	Is it possible to put your own custom classes inside
		gtkbuilder ui-files? Or do you need to do work on the
		gtkbuilder side for that to work?
baedert		you mean custom widgets?
mattiasb	And if it works: does it also work for, say, gjs?
mattiasb	baedert: ah, yeah exactly
xjuan		mattiasb, yes you can
xjuan		what I do not remember is if you need to have your
		class referenced or not
mattiasb	What I'm after is to have a main-window.ui file be a
		template for my custom window widget (inheriting from
		GtkWindow) and then let that ui file use some other
		templated custom widgets inside them etc.
mattiasb	xjuan: that sounds encouraging.
xjuan		mattiasb, yeah as long as you have a properly named
		_get_type() function it should work automatically
mattiasb	xjuan: cool, I need to experiment with this a bit.
xjuan		I do not know how javascript bindings works
xjuan		I mean, does the binding create a new derived GObject
		class when you define your JavaScript class?
xjuan		I know that python binding does
xjuan		but I never used gjs
mattiasb	xjuan: I have no idea. :/
xjuan		mattiasb, so when you make your custom widget derive
		from GtkWindow for example
xjuan		newType.prototype = Object.create (parent.prototype);
xjuan		newType.prototype.constructor = newType;
xjuan		I assume you do something like that ^^
xjuan		or perhaps there is a special gjs function to derive
		from a Gtk class
xjuan		so I wonder if g_type_get_from_name("newType") returns
		a new GType :)
mattiasb	xjuan: yeah there's some special class-stuff there.
		Basically it looks like this:
		https://git.gnome.org/browse/gnome-maps/tree/src/notification.js#n29
xjuan		mattiasb, looks nice
mattiasb	but so yeah what I need to do is check whether the
		gtypes get registerred somewhere?
mattiasb	..that or just try it out and see if it fails :)
xjuan		yeah just try to create a widget using GtkBuilder
mattiasb	and if it doesn't work I know where to start and fix it :)
mattiasb	thanks a lot!
xjuan		if it does not work, try creating an instance manually
		before using GtkBuilder
