fl_gc not available on wayland

[Mo_Al_]

Hello

It seems the fl_gc global variable is not available when building for wayland. I'm wondering if this was just an oversight, or if there's another way to check for graphics context?

Thank you

Wayland uses a different API: https://fltk.gitlab.io/fltk/osissues.html#osissues_wayland

See:

/** Returns the Wayland display in use */

extern FL_EXPORT struct wl_display *fl_wl_display();

/** Returns the wl_surface associated to a shown window */

extern FL_EXPORT struct wl_surface *fl_wl_surface(struct wld_window *xid);

/** Returns a platform-specific reference associated to a shown window */

extern FL_EXPORT struct wld_window *fl_wl_xid(const Fl_Window *win);

See

extern FL_EXPORT cairo_t *fl_wl_cairo();
Defined in Fl/platform.H
