2022-03-21Fix silly MSVC 2010 parser warningsAlbrecht Schlosser
Code like "void copy(const char */*stuff*/, ...)" would issue the warning "'*/' seen outside comment" which is formally true but ... These warnings don't appear with newer MS compilers, but I fixed them anyway.

2021-08-27Remove compiler warnings '-Wextra-semi' (see also PR #266)Albrecht Schlosser
I compiled with `-Wextra-semi -Werror=extra-semi` on Linux and Windows (cross-compiled on Linux) and removed all "extra semicolon" warnings I could find. I didn't check on macOS (yet). Note: Linux configured with and w/o Pango but not w/o Xft. Compilation with other options (e.g. Cairo) might still emit such warnings.

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.

2020-01-15Fix uninitialized vars in calls to fl_clip_box() (issue #6)Albrecht Schlosser
The main fixes are only to avoid static code analyzer warnings reported in issue #5, but there are also minor bug fixes included. These bug fixes are more of theoretical concerns though. Close #6.

2018-06-23Removed macro FL_PORTING, as it has been more confusing than helpful.Matthias Melcher
The original intention of FL_PORTING was to mark all places in the source code where changes are required to port FLTK to a new platform. Thanks to the driver system, this approach has become somewhat misleading, so I removed all references. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12969 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
