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.

2025-03-16Fix font termination bug from 2e1730d2f0f1 (#1221)Albrecht Schlosser
See also #1223, and thanks to Gonzalo for finding it.
2025-03-15Fix potential buffer overflow on Windows when loading fonts (#1221)Albrecht Schlosser
This commit is bigger than necessary to fix the buffer allocation but it also prevents some unnecessary string copies: the font name is converted from UTF-16 to UTF-8 directly in the buffer used later. Code reformatted and clarified as well, some duplicated code was removed.
2025-01-22Windows: replace "Arial" by "Microsoft Sans Serif" for the FL_HELVETICA ↵ManoloFLTK
font family Users who need the old behavior for strict backwards compatibility under Windows can load the previous (Arial) font at program startup with only a few lines of code: #ifdef _WIN32 // reset Windows fonts to pre-1.4.2 state Fl::set_font(FL_HELVETICA, " Arial"); Fl::set_font(FL_HELVETICA + 1, "BArial"); Fl::set_font(FL_HELVETICA + 2, "IArial"); Fl::set_font(FL_HELVETICA + 3, "PArial"); #endif

2022-01-16Rename FL/fl_string.h to FL/fl_string_functions.hAlbrecht Schlosser
This is part 1 of the final fix for a previous name clash on case insensitive file systems (fl_string.h vs. Fl_String.H).

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

This second step replaces FL/x.H with FL/platform.H in all source files. Dependencies have been adjusted as well. This commit completes the replacement of FL/x.H with FL/platform.H. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12641 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2017-05-17Introduce HiDPI + rescaling support for the X11 platform (+ partial support ↵Manolo Gouy
for WIN32) Corresponds to STR #3320 1) HiDPI support consists in detecting the adequate scaling factor for the screen on which FLTK maps a window, and scaling all FLTK units by this factor. FLTK tries to detect the correct value of this factor at startup (see more details below). Environment variable FLTK_SCALING_FACTOR can also be used to set this value. 2) Rescaling support consists in changing the scaling factor of all FLTK windows in reply to ctrl/+/-/0/ keystrokes. More details for the various platforms : - X11: Support is very advanced. Some details need still to be improved. Automatic detection of the correct starting value of the scaling factor works well with the gnome desktop. The present code contains no support for this on other desktops. FLTK_SCALING_FACTOR provides a workaround. -WIN32: Support is incomplete at this point, although many test applications have partial or complete HiDPI and scaling support. The current value of the system's scaling factor is correctly detected at application startup. Apps respond to changes of this value in real time. Support needs to define the FLTK_HIDPI_SUPPORT preprocessor variable at compile time. This way, standard builds produce a code with the default WIN32 HiDPI support, that is, where all graphics goes to an internal buffer that gets enlarged by the system and then mapped to the HiDPI display. To experiment with (or develop) the new HiDPI support requires a modified build procedure in which FLTK_HIDPI_SUPPORT is defined at compile time. When the support will be complete, the requirement for the definition of this preprocessor variable will be removed. The present commit contains support for a single scaling factor. Eventually, per-screen scaling factors should be implemented, as done for X11. - MacOS: this commit does not give new HiDPI for this platform. Eventually, window rescaling in reply to command/+/-/0/ is desirable. Per-screen scaling factor makes no sense on this platform because the OS itself takes care of the difference between the resolutions of traditional and retina displays. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12239 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

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

2016-02-09Fix MSWindows issues from last refactoring.Matthias Melcher
During the last refactoring on OS X, a few thing were relocated into new files, mainly to avoid ifdef's and use C++ inheritance in a driver system instead. This commit makes FLTK compile again under VC2013 with IDE files generated by CMake. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11141 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
