Hey, I’m trying to create a custom window title bar. I noticed there’s a flag for undecorated windows (glfwWindowHint(GLFW\_DECORATED, GLFW\_FALSE)), but the issue is, I can’t resize it by dragging the edges of the window. I saw there are lots of solutions for solving this for Windows OS, but i can’t find any solution for MacOS.

Hi @Nic-Urb, welcome to the GLFW forum,

The only solution I can think of is to add a resizing control yourself. This is how the [Dear ImGui docking branch](https://github.com/ocornut/imgui/issues/2109) gets undecorated resizable windows with GLFW.
