Hi!

What’s the correct way to handle custom window decorations on Linux with glfw? (Both under X11 and Wayland)

Currently, implementing these is very platform dependent. For example, on Windows I’m using a custom windowProc function to handle Aero and draw window shadows on a borderless window. On macOS, I’m using a regular window but use Apple’s cocoa API to make the title bar transparent and move it into the client area.  
On Linux however, I can’t seem to find a proper way to do it. From what I can tell, glfw uses libdecor to draw the decoration client sided but there’s no way to customize it I believe.

My goal is to achieve something similar to this, just on Linux. Resizing, moving and drawing of the window border/shadow being handled by libdecor but drawing the title bar ourselves.

Hi!

I didn’t initially answer this as I’m not that familiar with Wayland decorations, however given no-one else has responded I think the initial place to look at might be the fallback decorations GLFW uses:

Perhaps there might be some way to combine this with an undecorated GLFW window, drawing these decorations over the client area?
