Generate FL/fl_config.h rather than FL/abi-version.h
... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0

This indicates that -any Cairo calls are available. In this case you get something like this: - -// static variable holding the last Cairo context FLTK set: -cairo_t* Fl::cr; - -// Make cr draw in this window. This hides the ugly platform-dependent -// part of getting Cairo going: -void Fl::cairo_make_current(Fl_Window*) - -*** POST 1.3 potential Cairo use: -// Set cr to something you made yourself. This lets you reuse functions -// that use cr, and also tells FLTK that cr is not one of its own and -// thus cannot be destroyed or reused for a different window: -void Fl::cairo_make_current(cairo_t*) - -Second there is the FLTK_USE_CAIRO configuration option. This means that all -drawing is done using Cairo. In this case when a widget draw() method is -called, it is exactly as though cairo_make_current(window) has been done. -*** - -Note that it should be possible to compile so FLTK_HAVE_CAIRO works even -if FLTK_USE_CAIRO does not, and so that turning on FLTK_USE_CAIRO does not -break any programs written for FLTK_HAVE_CAIRO. - - PLATFORM SPECIFIC NOTES ========================= |
