Overview ¶
Package drmeglbackend provides a Dear ImGui backend for Linux DRM/KMS + EGL.
It is intended for embedded or kiosk-like environments where rendering happens directly on a TTY without X11 or Wayland. Unlike the GLFW/SDL backends, this backend does not expose a real desktop window, so several window-management methods are implemented as compatibility no-ops.
