Re: [Tinycc-devel] Newcomer to TCC (and C) with a couple of questions..

[Joshua Phillips]

Hello.

- As far as I know, wxWidgets is exclusively a C++ library. Tcc is a C 
compiler. So tcc won't work with wxWidgets. The usual example of a C widget 
library is GTK+.

- I am unaware of wxWidgets doing garbage collection, but this doesn't make it 
very clear: http://wapedia.mobi/en/wxWidgets#3.

- You speak of GDI resources, which is a Windows concept. If you're dealing 
with GDI resources yourself, then no, they will not get garbage-collected.

- There is no garbage collection in C. Having said that, there's libgc - the 
Boehm Garbage Collector, which works with C.

Firstly, you can keep objects you don't need any more for as long as you want, 
before deleting them. This might make sense if you don't know you're not 
going to need an object again until you run a certain procedure.

Secondly. the only GUI example I can find in the TCC repository is an X11 one. 
Maybe I'm not looking in the right place. If there is a GDK example, it is 
probably very simple, and doesn't bother deleting the GDK objects, because 
they'll be deleted when the program exits. I don't advocate such programming 
style.

Hope this helps.
