Although the memory "leak" is not really an issue in this demo
program (memory is returned anyway), "fixing" the leak warning
issued by valgrind and address sanitizer demonstrates the new
feature to "bind" images.

Detected by valgrind :
==16102== Conditional jump or move depends on uninitialised value(s)

This widget offers the selection of all known FLTK schemes as a simple
widget based on Fl_Choice.
Some test and demo programs use Fl_Scheme_Choice to enable the developer
or user to switch schemes quickly for comparison.
Todo:
- add features to add new schemes during runtime (partially done)
- update status when the scheme is changed by Fl::scheme("...")

- Add internal fl_contrast_cielab() as the new default.
- 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.
- Add fl_lightness() convenience function for perceived lightness.
- Add fl_luminance() convenience function for physical luminance.

- replace enum value 'FRAMES' with 'const unsigned int frames'
- replace enum value 'DIM' with 'const unsigned int dim'
- remove commented statements that have never been used.
Note: this also changes uppercase enum values to lowercase constants.

Update unittest README
|
|
Change some method names to comply with FLTK style as discussed
in fltk.coredev, thread "Fl_Flex method name question".
* Rename Fl_Flex::margins(...) to Fl_Flex::margin(...)
(use singular form for all margin related methods)
* Remove Fl_Flex::setSize() and isSetSize() "backwards compatibility" methods
* Rename Fl_Flex::set_size(...) to fixed(...)
Note: the latter affects existing (pre-release) fluid (.fl) files: you may
want to edit and replace "set_size_tuples" with "fixed_size_tuples"

It was decided today it is ok to use utf-8 strings in source,
so consolidating.
|
|
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.

Many thanks to @darealshinji for contributing all the code
for this new FLTK image class (see branch Fl_ICO_Image of https://github.com/darealshinji/fltk).

This commit is similar to the patch given in STR 3477, oxy_v5.diff:
https://www.fltk.org/strfiles/3477/oxy_v5.diff
... with modifications, and updated to current FLTK code.

Only showing table's callbacks after table is initialized.
We're only interested in user interaction.

Add an invisible box as resizable() to 'demogrp' to avoid bad resizing
behavior while the debug terminal is enabled. The old version would
disable some buttons including the 'exit' button if the window was
resized to a smaller size.
Simplify the popup menu (remove strcmp()).
|
|
This new feature demonstrates that Fl_Flex can be used (almost) as
a drop-in replacement of Fl_Pack.
Add missing file to examples/.gitignore.
|
|
Support different margin sizes on all four edges. Default margin
and gap size is now 0 (compatible with Fl_Pack).
Doxygen: move the description from the constructor to the class
declaration which constitutes a "description".
Make some methods virtual and/or 'const'.
Clarify demo programs, make them even more "FLTK style".

This work is based on the repository and latest commit:

commit 36e4ed75a00daac825b87e81295818b4650991f5
Author: Karsten Pedersen <...>
Date: Fri Apr 23 12:06:16 2021 +0000
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.

|
|
Reorder buttons in the expected <tab> order (left to right, top down),
make window resizable, and remove unnecessary #include statements.
|
|
... to test the deactivated status of integrated widgets.
|
|
Also make clear that these options require, for now, Fl_Double_Window to work cross-platform.
|
|
- set variables UNITTEST_LIBS and UNITTEST_LIBS_SHARED appropriately
- use these variables in build instructions
This includes normal and shared builds with and w/o OpenGL.
|
|
- remove no longer used filenames
- reorder to separate generated files from executables
- add comment on how to create list of generated files
|
|
|
|
Note that this fix includes "../src/flstring.h" which makes the source
file no longer compileable without the full source code, e.g. by
using "fltk-config --compile ...". This might be fixed later. (?)
