Hi,
I just released the bindings for Go at https://github.com/gen2brain/iup-go.
I know there were previous attempts, my bindings include IUP C source code
that is compiled together with bindings.
That means it is enough to just `go build` your app, or add tags like `gtk`
to force GTK+ on macOS and Windows, and even `motif` tag, to build for
Motif.
I also rewrote many examples and added some new ones, like postmessage,
which uses goroutine, and an image example that shows how to use Go
standard libraries to load images.
These are only bindings for core IUP, IM is not needed as Go has jpeg, png,
gif, etc. in the standard library. CD I cannot include easily and it needs
many dependencies, so no additional controls.
I just added the support for GLCanvas, but I really miss Matrix and Cell
controls.
I added the Cocoa code and sample screenshot on purpose, hope it can
attract contributions. Native controls I believe are more relevant than
ever.
There was some attempt, libui/ui project in C, with Go bindings, some
Googler started, but there is no progress for years, I guess it is not an
easy task to do from scratch.
Btw. I noticed that postmessage crashes in Motif, there is an easy fix,
user_data is just not passed:

NULL);

user_data);
}
I also have issues with the IupThread example I wrote, it seems to
start/stop correctly, but it crashes on IupClose.
It is a simple example, I will try to rewrite it in C to see if it happens
there.
Thank you for the amazing UI toolkit.
Milan
