2022-09-27Simpler code to support FLTK widgets in macOS OpenGL 3 windows.ManoloFLTK
Also, the application-level code to add widgets to a GL3 window becomes platform-independent.
2022-09-25Add cross-platform support for adding widgets to an OpenGL3-based Fl_Gl_Window.ManoloFLTK
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.

2022-08-12Improve automatic documentation generationAlbrecht Schlosser
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
2022-08-07Fl_Flex: support different margin sizes, improve docsAlbrecht Schlosser
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".

2022-04-13Make Fl_Image::copy() 'const', including all derived classesAlbrecht Schlosser
Copying an image does not (and must not) change the original object, hence copy() should always be 'const'. This is *necessary* if the given Fl_Image object is 'const'.

2022-02-06OpenGL implementation of all `fl_` "Drawing Fast Shapes" graphics calls (#385)Matthias Melcher
* Fix build system for unites, * Updated unittest to check OpenGL drawing. Making sure that OpenGL drawing is exactly the same as native drawing to make FLTK widget rendering look the same in GL windows. * Make OpenGL optional. * Implemented clipping in OpenGL * unites drawing fast shapes * Fixed CMake * Updating unittest. Added tests for fl_pi and fl_arc (int) Renamed tab to render complex shapes. * Improved OpenGL FLTK drawing emulation. * Fixed GTK ROUND DOWN BOX * Fixing Makefile for unittest * Correctly aligning OpenGL text. * Fixed text alignment in GL windows. Explained the "FLTK over GL " example in Cube. * Overlapping test. * Better GL graphics alignment. * Drawing the focus rect. * Adding Alpha Channel support for GL. * Added FLTK-on-GL documentation.

2020-09-21PDF docs: generate LaTeX header file from sourceAlbrecht Schlosser
The LaTeX header file used when creating PDF documentation depends on the doxygen and latex versions, respectively. The old header file 'documentation/src/fltk-book.tex.in' had been generated manually and needed to be updated for new doxygen versions which made the PDF documentation generation dependent on the doxygen/latex versions on the build system. The new LaTeX header file 'fltk-book.tex' is generated by doxygen, i.e. taking into account the doxygen and latex versions on the build system and "edited" to include the page title defined in the new file 'documentation/src/fltk-title.tex.in'. This makes the PDF documentation independent of the doxygen and latex versions of the build system.
