What is the meaning of this piece of code?

@handler : (GObject, Base) ~ Nil;

@objeck What does (GObject, Base) mean? handler has two data types? This poc is confusing!

[objeck]

It's the callback handler for a GTK event. Here's an example.

Hi @iahung2, it has been months since I have looked at the generated code. I would start with this demo, which worked on Linux and Windows. The demo was used as a guide for code generation.

It may be picked up if needed. As time permits, I want to create an ML framework based on TensorFlow or MXNet.

Is @handler : (GObject, Base) ~ Nil; valid Objeck code? What does it mean? Which data type is (GObject, Base)?

[ghost]

@objeck Noted that ~ on Objeck is used for the return type of methods and functions. I think this syntax is one of the obscure feature of Objeck called alias. Please correct me if I'm wrong.

[objeck]

You are correct. The alias keyword is used to reference complex functional types. Here's an example.
