I couldn't test this though.

This file was not in use and we currently don't intend to use CDash.

Make sure that the first chart entry is not zero because this wouldn't
show the first part of FL_SPECIALPIE_CHART separated from the circle.
|

Add forgotten parameter docs and some minor code fixes.

This commit makes the local, static drawing functions in the source
file available for subclasses by converting them to static protected
methods as requested by STR 2022.
The source and header files have been reformatted according to the
CMP, documentation for the new protected methods was added.
Source code *functionality* has not been changed.
This resolves and closes STR 2022.
Todo:
- investigate whether these drawing methods wouldn't better be
member functions and "convert" them if applicable
- investigate whether the internal struct FL_CHART_ENTRY could become
a local part of the Fl_Chart class, maybe Fl_Chart::Entry.
- rename private member variables with trailing underscore (see CMP)

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.
|
|
For some reason, the \file Doxygen command is absolutely required.
|
|
The new name reflects better the role of this bool member variable.
Also, add explanatory comments about the use of this variable.

Helper function convert_crlf() from file fl_wayland_clipboard_dnd.cxx has been
repaired by commit a4b33f8 (13 jan 2023). But the same function was also in
file Fl_cocoa.mm. This commit moves the repaired code to class Fl_Screen_Driver
and has both fl_wayland_clipboard_dnd.cxx and Fl_cocoa.mm use it.

Add two auxiliary source files needed to properly build libpng
for the ppc64 architecture.

src/drivers/Cairo/Fl_Cairo_Graphics_Driver.cxx:
- fix font_name_process() out of bounds memory access
- unify/align font_name_process() code (see also Xlib/xft)
- fix font name string allocation
src/drivers/Xlib/Fl_Xlib_Graphics_Driver_font_xft.cxx
- unify/align font_name_process() code (see also Cairo_Graphics)
- fix font name string allocation
Todo: move common code to Fl_Graphics_Driver or another common file.

- replace strchr() with memchr() because buffer is not nul-terminated
- fix '*(p+1)' potentially accessing memory out of bounds
This fix also prevents
- multiple memmove() calls
- multiple searches from the beginning of the string
|
|
- add newline (\n) before string output
- remove quotes (')

- 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
|
|
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("...")
|
|
This basic version of class Fl_Scheme contains only static methods that
are needed for Fl_Scheme_Choice and further extensions.
