Re: [boost] [ANN] Boost.UI - a new C++ GUI library

I appreciate that someone has taken the (huge) step towards a cross platform gui for c++ within boost, it's really something that I think it's a big step forward for both boost and C++. (I havn't had the time to more than glance through the examples) It would be really great if it's crossplatforminess event extended to android\ios\web assembly. /Viktor On Fri, Sep 29, 2017 at 7:51 PM Nat Goodspeed via Boost < boost@lists.boost.org> wrote:

Yup, that's pretty much the subset of the io_service API I had in mind.

The point is to open up your event dispatch so it can coexist with whatever existing system the user is already using.

Yes. Many applications and even frameworks want to own the main loop. By default, Asio is one of them. Fortunately it does have these integration-friendly alternatives.

Since you propose a Boost library, it would be a valuable exercise to consider how best to integrate your framework with Asio -- especially considering that something very like Asio is well on its way to becoming part of the C++ Standard.
