I am working on the UI library and bindings for Go. Still not finished, but currently, the same app can be compiled for Win32, Cocoa, GTK2, GTK3, GTK4, Qt5, Qt6, and Motif. There is a web browser control, a GL canvas, and a regular canvas. I still work on the native table control, though.

Does IUP have a table control? I looked at the IUP website and didn't see one.

Treeviews are where the rubber meets the road, IMHO.

Impressive work!

IUP has custom-drawn controls for tables and cells (additional controls), and it uses another CD (canvas draw) library for that, not internal IUP Draw functions. I also started rewriting that to use the core IUP drawing functions instead. I also added a few more drawing functions, for rounded rectangles, bezier curves, and gradients. But ALL drivers, including Motif, have native table controls, so I really want to add one. Edit: Also, the GLcanvas control now has an EGL driver, with native Wayland support for GTK3, GTK4, and Qt6 (needs private headers). I modernized a bit of everything, added support for APPID, DARKMODE, etc. Linux uses xdg-open rather than hardcoding browsers. Win32 driver is not using the Internet Explorer web control but the WebView2 with custom loader, on GTK, you do not have to worry about the WebKitGTK, it will find the correct library with dlopen, etc, etc. But, there is still a lot to do.
