WxWidgets - Event table vs Connect ()?

Question

I just started learning wxWidgets, version 3.0, with C ++. I noted that event handling in wxWidgets is done using event tables. But one tutorial also mentioned Connect () - in fact, it simply said: "Event tables will be used in this tutorial, not Connect ()."

I would like to know what is the philosophy of Event tables and for Connect ()? What is the difference when one more suitable than the other ... Thank you.

First, do not use Connect() , which has been replaced by Bind () , which is the best.

Secondly, both static (using event tables) and dynamic (using Bind() ) event handling methods work, and you can use whatever you prefer. Personally, I recommend using Bind() because

• It is much more flexible: it can be used to connect events on one object to any other object or even to a free function or, in C ++ 11, lambda .
• This is safer and catches the most common errors, such as using the wrong signature of the event handler at compile time.
• It is "dynamic", i.e. You can connect and disconnect the handler at any time.

The main advantages of event tables are:

• They are slightly shorter, especially in versions prior to 3.0.
• They are much more common in documentation, examples, textbooks, ... just because they had a 15-year start on Bind() .

However, they are inconvenient to use because they require a subclass (getting a new class) of the object to handle non-command events in it, and they do not detect all errors during compilation, which allows you to write code that compiles normally, but fails during fulfillment.
