> 1) I want to write a GUI code once > 2.1) I want to ship something that looks the same on Windows / Linux / MacOS > 3.1) I want to ship a small and efficient binary well, with Qt I write my code once, which looks the same on windows / linux / osx / $nicheos and the result is fairly performant - I've got tables with tens of thousands of elements which update at rates greater than 100hz and the UI does not bat an eye. I'm not even using the GPU-based scene graph (QtQuick) but instead uses the CPU-based raster engine. Here's the software I'm developing : https://github.com/OSSIA/score/ https://github.com/OSSIA/score/ So what is missing ? For what it is, the binary is relatively small (and I also link against LLVM and a few other large libraries, and am not even doing global static linking + LTO...).
