This allows FLTK apps to use the recent frameworks when they run on recent
macOS versions even if the minimum supported macOS version of these apps is more
ancient than the framework.
Some applications insist on sending XDND protocol version 5 and
rejected (ignored) FLTK as DND receiver because we allowed only
protocol version 4. Known apps: Google Chrome and Chromium.
This commit enables XDND protocol version 5 in FLTK programs as
DND receiver.
The previous procedure using CGWindowListCreateImageFromArray()
is obsoleted in macOS 15.0 .
The new procedure requires an additional framework: ScreenCaptureKit;
FLTK uses it only for macOS ≥ 15.0
A change to Fl_Input_Choice callbacks slipped into
fd791a068e.
This Commit removes that change. It may need to be
fixed and reapplied later in its own Commit.
- swap 3rd and 4th parameter of fl_contrast()
- change 'Fl_Fontsize fs' to a neutral 'int size' parameter
- clarify documentation of fl_contrast_level() and that different
contrast algorithms use different level values
- clarify that level 39 for the CIELAB mode results in "sufficient"
contrast, i.e. /readable/ text which is the only intention of
fl_contrast().
Reasoning: swapping the arguments looks more natural, i.e. the context
before another argument (size) is what one would usually expect. Since
the 'size' argument doesn't have be a font size, making it a simple
'int size' is more flexible and correct for future extensions.
- src/fl_contrast.cxx:
- FL_CONTRAST_LEGACY: reset black/white threshold from 55 to 50
- FL_CONTRAST_CIELAB: change default contrast level from 55 to 39
- test/contrast.cxx:
- set default contrast mode to CIELAB
- add "random color" button to test random foreground colors (text)
- slightly increase terminal size
- make the Fl_Terminal widget the resizable() of the window
- Remove find_library(LIB_GLEW ...) from 'resources.cmake'
- Use the variable FLTK_GLEW_DIR to "find" a user supplied GLEW library
for OpenGL3 example programs (examples/OpenGL3*.cxx).
Both static and shared libs (DLLs) are supported, but the static
library is preferred to avoid DLL dependencies.
- Define preprocessor macro 'GLEW_STATIC' by CMake compile definitions
if and only if the static glew library (glew32s) was found and linked.
The previous code defined 'GLEW_STATIC' unconditionally in the source
code which led to undefined references if a shared lib (DLL) was used.
- don't use pkg-config to find Cairo if FLTK_CAIRO_DIR is set
- use FLTK_CAIRO_DIR to locate Cairo headers and DLL if it is set
- otherwise try to find Cairo with pkg-config anyway
This prevents accidentally "finding" the system Cairo libs provided
by MSYS - which would tie the FLTK library and user programs to MSYS,
i.e. it would make FLTK programs depend on the MSYS installation.
