2024-04-17Separate FLUID user documentation, screen shot automation (#936)Matthias Melcher
* CMake integration, no autotiools * alignment panel is now correctly renamed to setting panel * source view is now correctly renamed to code view * Merge FLTK FLUID docs into FLUID user manual. * Add two simple entry tutorials * Remove FLUID chapter form FLTK docs. * GitHub action to generate HTML and PDF docs and make the available as artefacts
2022-11-27macOS+OpenGL3: remove "warning: gl.h and gl3.h are both included"ManoloFLTK
2022-09-29Doc: more details about installation of GLEW.ManoloFLTK
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.

2022-02-06OpenGL 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.
2020-11-08Clarify offscreen drawing documentationAlbrecht Schlosser
... and rename drawing chapters (sections + subsections) according to our documentation conventions (prefix "drawing_"). documentation/make_pdf: fix copyright year.
2020-07-06Remove $Id$ tags, update URL's, and moreAlbrecht Schlosser
- remove obsolete svn '$Id$' tags from all source files - update .fl files and generated files accordingly - replace 'http://www.fltk.org' URL's with 'https://...' - replace bug report URL 'str.php' with 'bugs.php' - remove trailing whitespace - fix other whitespace errors flagged by Git - add and/or fix missing or wrong standard headers - convert tabs to spaces in all source files The only relevant code changes are in the fluid/ folder where some .fl files and other source files were used to generate the '$Id' headers and footers.

2018-02-09Replace "WIN32" with "_WIN32" or "Windows".Albrecht Schlosser
Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32". Replace "WIN32" in text and documentation with "Windows". Replace "MSWindows" with "Windows". To do: README.Windows.txt (and maybe other documentation as well) needs updates. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12655 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2009-03-21converted html tags to doxygen commands in documentation/src/opengl.doxengelsman
This was just the first round. A lot more work will be needed here because none of the gl_* functions are doxygenated, and there are a lot of html links to other pages to be tidied up! git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6706 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
