WindowScreen - How To Set Window To Current Screen Resolution Using LGI (Lua + Gtk)

WindowScreen.lua

local lgi = require('lgi')
local Gtk = lgi.require('Gtk', '3.0')
local Gdk = lgi.require('Gdk', '3.0')

--- I collect the value of the screen resolution
-- and I pick up its width and height
local screen = Gdk.Screen:get_default()
local width, height = screen:get_width(), screen:get_height()

-- Creates the window
local window = Gtk.Window {
	title = 'Window Screen',
	application = self,
	default_width = width,
	default_height = height,
	{
		Gtk.Label {
			use_markup = true,
			label = ('My resolution is: <b>%sx%s</b>'):format(width, height)
		}
	}
}

function window:on_destroy()
	Gtk.main_quit()
end

window:show_all()
Gtk.main()
