Since FLTK 1.4.0 inclusion of FL/Fl.H is no longer a requirement
unless class Fl is used (e.g. Fl::run()) or if it is used to include
other headers like FL/Enumerations.H
Add Doxygen-formatted description of the Wayland backend
Add bundled-libs.dox
Delete README.bundled-libs.txt
Move "Development" page to "Development of FLTK" chapter
Some Wayland specific files are generated by the build process with
configure + make in the source tree.
These files are now ignored by the Doxygen documentation process.
This file is now compatible up to Doxygen 1.9.5, i.e. there are
no warnings about obsolete parameters when generating the docs.
Current git 'master' of Doxygen (1.9.6: not yet released) issues
some warnings but these will hopefully be fixed in Doxygen.
Oldest tested Doxygen: 1.8.17 - older versions may emit warnings.
Ignore error if docs are not generated using a git working tree, for
instance from a downloaded tarball or zip file. This is only a
temporary solution for issue #499 (see "FIXME" comment).
Execute doxygen only if it is available. i.e. found by CMake.
Under non-macOS platforms, the key is to call glUseProgram(0); after having used OpenGL 3
which allows to then use OpenGL 1 and draw FLTK widgets over the OpenGL3 scene.
Under macOS, this is impossible because macOS GL3 contexts are not compatible
with GL1. The solution implemented here is to create an additional Fl_Gl_Window
placed above and sized as the GL3-based window, to give it a non opaque,
GL1-based context, and to put the FLTK widgets in that additional window.
Note: the syntax of command/switch `sed -i` is slightly different
on macOS vs. Linux and should not be used.
Move .gitignore parts referring to /documentation/ to their own file
'documentation/.gitignore' and add new generated file(s).
This removes the need to edit the copyright year before generating
the documentation (every year, in several files) and adds some
technical information (doxygen generation date, doxygen version,
and FLTK Git revision) in both HTML and PDF docs.
- auto-generate copyright year (current year) used in several places
- include FLTK Git revision in HTML and PDF docs
- include generation date and doxygen version
- replace special html footer which didn't work well with default footer
Support different margin sizes on all four edges. Default margin
and gap size is now 0 (compatible with Fl_Pack).
Doxygen: move the description from the constructor to the class
declaration which constitutes a "description".
Make some methods virtual and/or 'const'.
Clarify demo programs, make them even more "FLTK style".
