Usage :

- In an overridden widget draw method, do

and obtain the cairo context value adequate to draw with cairo to

- Creation of a new Cairo based scheme for FLTK

2 WAYLAND SUPPORT FOR FLTK
==========================
It is possible to have your FLTK application do all its windowing and drawing
through the Wayland protocol on Linux or FreeBSD systems.
All graphics is done via Cairo or EGL. All text-drawing is done via Pango.
On Linux and FreeBSD systems, and provided a Wayland compositor is available at run-time,
it is possible to have your FLTK application do all its windowing through the
Wayland protocol, all its graphics with Cairo or EGL, and all text-drawing with
Pango. If no Wayland compositor is available at run-time, FLTK falls back to
using X11 or OpenGL for its windowing. Cairo and Pango remain used for graphics
and text, respectively.
Environment variable FLTK_BACKEND can be used to control whether Wayland or
X11 is used at run time as follows:
- if FLTK_BACKEND is not defined, Wayland is used when possible, otherwise
X11 is used;
- if FLTK_BACKEND equals "wayland", the library stops with error if no
Wayland compositor is available;
- if FLTK_BACKEND equals "x11", the library uses X11 even if a Wayland
compositor is available;
- if FLTK_BACKEND has another value, the library stops with error.

The FLTK Wayland platform uses a library called libdecor which handles window decorations

this form of libdecor. Optionally, OPTION_USE_SYSTEM_LIBDECOR can be turned on to have FLTK

with FLTK 1.4 and the Wayland platform, X11-specific code will not compile. In particular,
the common FLTK 1.3 construct :
3 PREPARING PLATFORM-SPECIFIC CODE FOR THE WAYLAND PLATFORM
===========================================================
While platform-independent source code prepared for FLTK 1.3 is expected
to be compatible with no change with FLTK 1.4 and the Wayland platform,
platform-specific code may require some attention.
3.1 Handling X11-specific source code
-------------------------------------
If an FLTK 1.4 application contains X11-specific code, execution of this code
in the context of an active Wayland session can produce malfunctions or program crashes.
To ensure that X11-specific code gets called only when an X11 connection is active,
check that function fl_x11_display() returns non-NULL before using any X11-specific
function or variable.
3.2 Handling X11- and Wayland-specific source code in the same app
------------------------------------------------------------------
The recommended way to prepare and use platform-specific code that would contain
both X11-specific and Wayland-specific parts is as follows :
a) Organize platform-specific code as follows :
#include <FL/platform.H>
#ifdef __APPLE__
*** macOS-specific code ***
#elif defined(_WIN32)
*** Windows-specific code ***
#else
*** X11-specific code ***
*** Wayland-specific code ***
#endif
will choke at compile time because it exposes X11-specific code to the non-X11, Wayland
environment. This should be written instead :
#include <FL/fl_config.h>
#ifdef __APPLE__
*** macOS-specific code ***
#elif defined(_WIN32)
*** Windows-specific code ***
#elif defined(FLTK_USE_X11)
*** X11-specific code ***
#endif
Moreover, the new FLTK_USE_WAYLAND preprocessor variable is available to bracket
Wayland-specific source code.
b) Make sure to use distinct names for global variables and functions
in the X11- and the Wayland-specific sections.
c) Check that function fl_x11_display() returns non-NULL before using any X11-specific
function or variable, and that fl_wl_display() returns non-NULL before using any
Wayland-specific function or variable. Make sure that fl_open_display() was called
directly or indirectly before using any such symbol.
3.3 Forcing an app to always use the X11 mechanism
--------------------------------------------------
Alternatively, it's possible to force an FLTK app to use X11 in all
situations by calling function fl_disable_wayland() early in main(), before
fl_open_display() runs. FLTK source code and also platform-specific
code conceived for FLTK 1.3 should run under 1.4 with that single change only.
