Usage​

OnChanged is an Seam index to be used in the New constructor. OnChanged detects when an instance changes, e.g. when it changes color or size.

You can use it like so:

local Object = New("Frame", {
    -- Properties

    [OnChanged] = function()
        -- When the frame changes, this function calls back
    end
})

You can also track states, like so:

local MyValue = Value(0)

local MyChangedConnection = OnChanged(MyValue, function()
    print(MyValue.Value) -- Prints MyValue.Value when it changes
end)

MyValue.Value = 1 -- Change value, which fires the callback

MyChangedConnection:Disconnect() -- Disconnects the signal
