Help to implement Fly-Pie in hyprland

[Armando Escobar]

Hi, I am writing a program that seeks to implement the same functionality as fly-pie but for hyprland (A dynamic tiling Wayland composer), this composer solves the limitations listed here. The problem I've found is that I can't understand how you managed to create the visual part of fly pie in gtk, things like: the positioning of the items, the drag and drop function, where the rendering functions are executed ?
