Re: Can a Multi-Threaded GTKMM Application Use std::thread Rather Than Glib::Thread?

[Chris Gordon-Smith <c gordonsmith gmail com>]

Hello Harry

Thanks for the response.

What I want to do is minimise the dependencies that my code has on
various libraries other than the C++ standard library. 

Since the C++ standard library does not include a GUI, I use GTKMM,
which I'm very happy with. I have separated out my GUI presentation code
from the rest of the code, and only the GUI presentation code has to
include <gtkmm.h>. But to get the multithreading for the GUI working, I
have now had to introduce a dependency on Glib <glibmm.h> in other parts
of my code. I have used wrapper classes to limit the scope of the
dependency to a small section of code, but I would have preferred not to
do this at all.

My question is: Could I have avoided use of Glib::Thread altogether, and
just used std::thread?

I think probably not, but thought I would ask.
