- add Fl_Scheme_Choice widget for quick scheme selection
- fix label alignment of selection box
- set selection_color()
- set selectbox()
- make the tree the resizable() of the window
FL_OVERRIDE is defined as `override` for C++11 and higher
FL_OVERRIDE is defined as `override` for VisualC 2015 and newer
Don't interfere with Fl_Widget::override()
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"
As reported in fltk.coredev in thread
"CMAKE build with build examples. On and test OFF fails"
$ cmake .. -D FLTK_BUILD_EXAMPLES=ON -D FLTK_BUILD_TEST=OFF
failed with: Unknown CMake command "FLTK_RUN_FLUID".
The code failed with 2 or more widgets when FLTK would trigger
partial redraws of the widgets, unless the Fl_Gl_Window was FL_DAMAGE_ALL.
This commit also adds a second FLTK widget to example/OpenGL3test to
check this multiple widget situation, and fixes an error where operator ! was used
instead of ~ .
This commit allows to switch between FL_DOUBLE / FL_SINGLE modes
in widget-containing GL3 windows.
Demo program examples/OpenGL3test is modified to show FLTK widgets
even if the platform does not support OpenGL 3.
Under non-macOS platforms, the key is to call glUseProgram(0); after having used OpenGL 3
which allows to then use OpenGL 1 and draw FLTK widgets over the OpenGL3 scene.
Under macOS, this is impossible because macOS GL3 contexts are not compatible
with GL1. The solution implemented here is to create an additional Fl_Gl_Window
placed above and sized as the GL3-based window, to give it a non opaque,
GL1-based context, and to put the FLTK widgets in that additional window.
Elaborated on Fl_Cairo_Window's use of FLTK style coordinates,
and how this differs from cairo's default native normalized
coordinate system, and shows how to switch from one to the other.
Also, small comment fix to the cairo example regarding the "X" color.
Albrecht submitted this in issue 358.
Tested the variations:
cmake .. -- examples and cairo off
cmake -D FLTK_BUILD_EXAMPLES=on -- examples on, cairo off
cmake -D FLTK_BUILD_EXAMPLES=on -D OPTION_CAIRO=on .. -- examples on, cairo on
When examples are 'on', they build into the bin/examples directory.
Since this is the first cairo example in the examples directory,
it necessarily involved changes to the Makefile and to fltk-config
to properly handle the absence/existance of the cairo libs.
TBD: Add docs to the cario widget describing coordinate system
and how it differs from the default cairo normalized coordinate system.
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.
