wxwidgets dynamic classes

I'm trying to learn this tutorial:

How come he never has to use delete after calling new? Shouldn't he add a destructor to the class?

well,
all process memory is reclaimed on exit, so for a simple fire and forget app
it's not such a big worry.

you could delete but as the prog is about to die anyway it's a waste of keystrokes!

remember tutorials generally get you up and running with
minimal checks and safety devices.
otherwise the examples get too long.

Okay. So in a bigger app where those dynamic things go out of scope, it would be important to free them. Just checking.

yes, for a long running daemon that stays on all the time it would be vital.

well, there are also things called smart pointers
