[tokyob0t]

So, im trying to make a custom GObject.Object with custom props/signals but idk how to

atm i know how to define custom props

local MyClass = GObject.Object:derive('MyClass')

MyClass._property.my_property =
    GObject.ParamSpecString('my_property', 'my_property', 'my_property', '', { 'READWRITE' })

MyClass._signal.my_signal = {} -- ????? idk what goes here

local obj = MyClass { my_property = 'Hello, World!' }
obj.my_property = 'New Value'

obj.on_my_signal = function() end -- do something

Huh, looks like LuaGObject lacks a way to define custom signals.

I'll have to study how PyGObject does it so I can adapt it to LuaGObject.

Ideally, I'd also want some syntactical sugar for defining signals because it seems to be quite complicated. Regardless, this is a glaring absence from LuaGObject and I'll try to rectify.

I wanted to note that I did give this a go for a few days, did a lot of reading to try to understand what's going on and didn't make any significant progress. This item is unfortunately stalled for now, but I'll probably pick it up again some time in the future.
