8 daysImprove documentation of functions dedicated to processing of emoji sequences.ManoloFLTK
11 daysEmojis: add support of keycap emoji sequences.ManoloFLTK
- It is expected that all emojis listed in the Wikipedia "emoji" article as of early 2026 are recognized as single glyphs by FLTK text widgets. - Document functions fl_utf8_{next|previous}_composed_char() relatively to the notion of "emoji sequence". - Remove signed/unsigned comparison compilation warnings.

2026-01-26Let text widgets handle gracefully composed unicode characters - Cont'd.ManoloFLTK
This commit adds support of another type of composed characters: flags. It also fixes Fl_Text_Buffer::prev_char() and Fl_Text_Buffer::next_char() that must use Fl_Text_Buffer::byte_at() to access to the content of the text buffer.
2026-01-24Let Fl_Text_Editor and Fl_Input handle gracefully composed unicode characters.ManoloFLTK
2026-01-21Improve handling of text containing context-dependent unicode points.ManoloFLTK
This commit makes platforms Windows and macOS compute string widths with the same mechanism as what is in place for platforms Wayland/X11: - the width of a string containing a single codepoint is computed and memorized in the table of character widths; - the width of a string containing several codepoints is computed as such rather than as the sum of the widths of its composing characters. The result is that FLTK text widgets input and draw correctly also complex emojis encoded with context-dependent codepoints. Function fl_utf8_remove_context_dependent() is no longer necessary.
2026-01-19All platforms use same code to remove context-dependent codepoints from text ↵ManoloFLTK
input. This commit introduces function fl_utf8_remove_context_dependent() that removes from an UTF-8 string its context-dependent codepoints. Platforms macOS, Wayland and X11 call this function to process UTF-8 text received from a character palette as input to FLTK text. This makes sure FLTK text-editing widgets process textual input equally and consistently across platforms, especially emojis entered via a palette. Platform Windows creates a series of separate system events to input an emoji via the character palette. For this reason, function fl_utf8_remove_context_dependent() is not used by this platform which does internally the same filtering of context- dependent codepoints.

2022-04-03Remove '#include <sys/stat.h>' from FL/platform_types.hAlbrecht Schlosser
- Add this include statement only where needed. - Rename Fl_System_Driver::stat() to flstat(). This fixes an issue when using some (!) MinGW 64-bit build systems that obviously '#define stat _stat64' or similar. This would result in compiler problems if 'stat()' is a member function of Fl_System_Driver.
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.

2016-03-29Remove the platform-dependent type xcharManolo Gouy
File fl_utf8.h defines the xchar type with a platform-dependent value (wchar_t or unsigned short). But it is used exclusively by WIN32 code (0 use in cross-platform code, 0 use in APPLE or in USE_X11 code). Thus, we can just get rid of this type and replace it by wchar_t where it is used. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11459 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

Searching for __APPLE, WIN32 or X11 did give me many false results.

2016-02-01Clean up fl_args for OS X.Matthias Melcher
Xcode and OS X have the annoying habit of adding the process number and debug information on the command line if an an app is inside a bundle. This is a little cleanup that I thought was useful while going through the code. A better solution would be to remove those system specific arguments from the argc/argv list entirely, as they appear totally unexpected for most developers. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11111 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2015-06-15Fix code indenting, remove dead code, improve documentation.Albrecht Schlosser
There was still old (dead) code that had been deactivated by '#if 0'. This code had been obsoleted by other functions, so it was time to remove the dead parts of the code. Many functions were not documented at all. I tried to add documentation, but I ran out of time. Todo: there are still some undocumented functions in src/fl_utf8.cxx. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10760 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
