As a follow-up to the discussion I used the posted screenshot demo
(thanks to Greg), redesigned it using Fl_Grid, and added it as a
new test program, including Makefiles and CMakeLists.txt.
New file: test/line_style_docs.cxx to create screenshot. Note that the
old test/line_style.cxx is not obsolete, it can be used to test the
line styles interactively.
Docs have been updated in both chapter "Drawing Things" and the
function description.
Also added the new demo to test/demo.menu under "Images for Manual...".
- FL/Fl_Grid.H: header file
- src/Fl_Grid.cxx: implementation
- examples/grid-simple.cxx: simple example program
- test/cube.cxx: use Fl_Grid for layout
- test/grid_alignment.cxx: test cell alignment and other functions
- test/grid_buttons.cxx: demo program as discussed in fltk.general
- test/grid_login.cxx: like test/flex_login.cxx but with Fl_Grid
- test/flex_login.cxx: modified to match test/grid_login.cxx
... "when there's no current window".
Silently ignore GLUT function calls that need a current window if the
current window is NULL, return 0 from functions that return an 'int'.
Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers().
This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise.
Note: the chosen implementation to ignore GLUT calls silently appears
to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error
messages and exit. The latter could be implemented as well but would
be much more work.
- remove separate libfltk_cairo to avoid cyclic dependencies, but
- keep a dummy libfltk_cairo in 1.4.0 for backwards compatibility
- move cairo/Fl_Cairo.cxx to src/Fl_Cairo.cxx
- add preliminary Cairo support for Visual Studio (MSVC)
Static linking is not affected by this change, but users building
with hand-made Makefiles will have to remove libfltk_cairo starting
with FLTK 1.4.0. The dummy library can be linked for backwards
compatibility but it will be removed later (in 1.4.x or 1.5.0).
The shared FLTK library libfltk.{so|dylib|dll|..} depends on libcairo
if and only if FLTK is built with one of the Cairo options. This has
always been the case for OPTION_CAIROEXT but is now also true if only
OPTION_CAIRO is selected, i.e. FLTK programs linked with a Cairo
enabled shared FLTK library will also be linked with libcairo. The same
is true for configure options --enable-cairo and --enable-cairoext,
respectively.
Preliminary Cairo support for MSVC now detects a Cairo installation
using the CMake variable FLTK_CAIRO_DIR which must be set by the user.
Note that this feature is temporary and may be changed in the future
for a better and more comfortable version.

- Keep old function as internal fl_contrast_legacy().
- Add fl_contrast_mode() to switch between fl_contrast() functions.
- Add fl_contrast_level() to fine tune fl_contrast() per mode.
- Add option to register and use a custom contrast function.
- Add test/contrast.cxx test program.
- Move all fl_contrast() related code to a new file src/fl_contrast.cxx.

This test helps check for issues with multiline widgets
drawing text properly.
The README-unittests.txt was added to help developers
add new unit tests easily.
This work is based on the repository and latest commit:

Added Fltk (LGPL) license.
This widget is similar to Fl_Pack and supports either one row or one
column of widgets but has some more features. Test and demo programs
are included:
test/flex_login.cxx: simple "login window" demo program
test/flex_demo.cxx: slightly more complex demo program
The original demo programs can still be compiled and built with
the new widget provided you '#include <FL/Fl_Flex.H>'.
Backwards compatible methods are included (except debug()).
The original widget has been modified to match FLTK standards and
enhanced in several ways, including:
- support box frames
- add HORIZONTAL and VERTICAL enum values (as in Fl_Pack)
- add horizontal() method (as in Fl_Pack)
- use type() rather than internal 'direction' variable
- add standard widget constructor (x, y, w, h, label)
- add margin and gap accessors rather than hard coding constants
- improve test and demo programs
- add documentation
- replace <vector> with array as required by FLTK CMP
- rename camelCase method names, keeping old names for compatibility:
- change 'setSize(Fl_Widget*, int)' to 'set_size(Fl_Widget*, int)'
- change 'bool isSetSize(Fl_Widget*)' to 'int set_size(Fl_Widget*)'
- remove debug() method
- add a way to "unset" fixed size: set_size(Fl_Widget *, 0)
- add layout() method to force recalculation of children
- unify resizeRow() and resizeCol() methods to avoid code duplication
- improve widget size calculation.

macOS Big Sur 11.3 introduced a new "security feature" such that
app bundles created from existing bundle templates in downloaded
files (tar distibutions, expanded) could no longer be executed
without unsetting the "quarantine" attribute. This commit fixes
this by creating all bundles from scratch.
Known *workaround* for older tarballs and snapshots:
$ xattr -d -r com.apple.quarantine xxx.app
- rewrite to use pkg-config with both autoconf + CMake
- remove hardcoded library names
- fix build dependencies and search directories
- remove or replace old and unused variables
- update README files
To be done:
- implement fallback for autoconf/configure if pkg-config is missing
- fix pango build (uses cairo internally)
- 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.
Test programs device and pixmap_browser use these new classes.
Class Fl_SVG_File_Surface can be optionally made non functional using the
--disable-svg configure option or turning off OPTION_USE_SVG in CMake.
Class Fl_EPS_File_Surface can be optionally made non functional using the
--disable-print configure option or turning off OPTION_PRINT_SUPPORT in CMake.
Some of the test programs were linked with libfltk_forms which was
unnecessary. The only one requiring this is the forms demo.
[CMake] reordered linked FLTK libs in dependency order.
We use the host system's `fluid` when cross-compiling. This must be
executable as `fluid`, i.e. it must be in the PATH or otherwise
defined, for instance as an alias.
This adds source png and xcf files for checkers pieces.
Also adds Makefile rules using xxd to convert .png -> .h as requested by Albrecht
in issue #29, (hmm, no comment numbers github?)..message dated "June 22nd 2019 4:22am PDT".
OP noticed our one-bit xbm images demonstrated an X11 driver bug
on certain hardware. While it's good that our test programs show the bug
(e.g. test/bitmap), it's bad that our games do.
Removed the 16 xbm files used by checkers which simulated transparency
with dithered images, and replaced with 4 "hexdump" png files that are
cleaner/simpler looking for such lores pieces (46x46 pixels).
Will follow up with a separate commit for the source .png and gimp .xcf
file I used for making the pieces.
The intention is to improve (and minimize) diffs when dependencies
are changed and `make depend' is executed.
(1) use `makedepend ... -w 20'
(2) `sort -u' the resultant file with some more "magic".
(1) makes sure that there is only one dependent file per line,
(2) makes lines unique since `makedepend' can output one file
many times which is redundant and makes diffs hard to read.
This uses 'mv', 'grep', and 'sort' in all FLTK library Makefiles.
Image libraries are intentionally left for a later update.
test/fracviewer.cxx wouldn't be compiled if the ABI version was
changed with configure and `make' was executed w/o `make clean'.
Add 'fracviewer.cxx' to list of source files to fix this.
Also add missing unittest_scrollbarsize.cxx to dependencies of
unittests.o.
Finally run `makedepend' to update dependencies.
Note: cherry-picked from branch-1.3 and adjusted to fit master (1.4)
The svn contained empty directories, e.g., test/blocks.app/Contents/MacOS/
Git apparently can't store empty directories.
The test/Makefile is modified to create these directories at build-time.
This change avoids a name conflict with CMake's auto-generated target 'help'
for "Unix Makefiles", "Ninja", and supposedly other generators as well.

so it is launchable by dropping any file on its icon. This is
done both for the configure/make and the CMake build systems
(the Xcode build system did that already).
The editor demo is the only one calling fl_open_callback().

The new XRender code uses 21 times less cpu than the old
read-back-and-manually-blend option. The blending is also
GPU-accelerated where possible, but works in software on
vesa/fb drivers.
