Apple clang version 12.0.5 (clang-1205.0.22.9)
Target: arm64-apple-darwin20.4.0
Warning appeared after upgrade to Xcode 12.5 in several files,
example:
In file included from Fl_Scroll.cxx:19:

Most coordinate calculations are done with the new inline function
int Fl_Scalable_Graphics_Driver::floor(int coord)
that is used by both the Windows and X11 platforms.
The issue lies in details how floating point scaled coordinates are converted
to integer values and its impact on the drawing of large SVG images.
This commit fixes the X11 platform.
The macOS platform is immune because drawing uses floating point
coordinates.
The Windows platform still needs fixing.
Use cairo-PostScript to output PostScript when pango is available.
This allows to draw in vectorial form any script.
Before, only the Latin script could be drawn to PostScript in vectorial form.
The deprecated methods are now calling the new methods to be
entirely compatible.
These methods should be removed in 1.5.0
(fix unrelated whitespace as well)
Previously (FLTK 1.3.x) the return value of a checked menu item
was FL_MENU_VALUE (4) but the docs warned explicitly:
"You should not rely on a particular value, only zero or non-zero."
* Fix Fl_Check_Browser.{H|cxx} indentation (#121)
... and some more whitespace errors as proposed by Greg
... in issue #121: Fl_Check_Browser--whitespace-patch.txt
Fixes#121
* Fix copyright years
Make maximum box corner radius and shadow width configurable.
See Fl::box_border_radius_max() and Fl::box_shadow_width().
Documentation: update image of box types.
Fixes#130
These unused typedefs are not used anywhere and should not be defined
at all.
Remove typedef 'Fl_String' as decided in fltk.coredev.
Remove typedef 'Fl_CString' as well for the same reason.
fix dead links to Fl_Group::resizable(Fl_Box *box)
reorder paragraphs to highlight different behaviour
add link to new "How does resizing work?" chapter in dox
A lot of code touched because low level functions needed to pass up
error messages reliably, and this had to propagate up the entire
driver hierarchy.
Tested OK *in English* on:
> Linux
> OSX 10.10.x
> Windows VS2017
> Windows mingw64
I have no way to test on Android, but it might work.
TODO: Needs testing in other languages to verify proper UTF8 error messages,
esp. with Windows VS, due to complexities with FormatMessage() -- see get_ms_errmsg()
Amended by Albrecht:
- rename union member variables as discussed
- add comments to new array_ union members
Fixes#96
Signed-off-by: Albrecht Schlosser <albrechts.fltk@online.de>
- 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.
- add 'can_expand' optional parameter to scale()
- don't expose name and e-mail of the nanosvg author in docs
- format example code according to the FLTK coding style
- fix (some) trailing spaces
FTR: all examples compile and work well with current FLTK 1.4.
(1) The new virtual method Fl_Image::release() which is equivalent to
'delete this' automatically extends to Fl_Shared_Image::release()
which makes the latter method virtual.
This new method in the base class makes Fl_Image::release() callable
on all objects derived from Fl_Image.
(2) Add virtual method Fl_Shared_Image *Fl_Image::as_shared_image()
This new method can be used to detect whether an Fl_Image instance
is an Fl_Shared_Image or not.
Add argument 'center' to position the message box centered over
the given x/y coordinates.
Add another method to supply a widget or window to center the
message box over.
Fix documentation and don't use INT_MIN to avoid having to
include limits.h in user code.
Add new function to set (x,y) position.
Reset to previous mode after innards is called by fl_* function.
Use magic number for preferred position state.
Note: several commits squashed and commit messages edited by AlbrechtS.
Metrowerks CodeWarrior was an ancient macOS compiler (discontinued
since 2005) that defined the macro __MWERKS__. Code using this macro
and several comments have been removed.
According to the documentation fl_font(face, size) may be called
"outside a draw context if necessary to call fl_width()".
This worked in 1.3.5 but did not in 1.4 (so far). I reworded the
docs to make clear that other measurement functions can be called
as well and refactored the code to make sure that fl_font(face, size)
will open the display if necessary.
The X11 specific overloaded function fl_open_display(Display *)
has never been documented but exposed (and "exported" in the ABI)
in FL/platform.H which is not necessary. This internal function
is now static and no longer exposed in the ABI.
Don't confuse with fl_open_display() w/o arguments which is still
exported and declared in FL/platform.H.
Unfortunately this typedef for shortcuts in Fl_Menu_Items etc.
can currently not be used with the full (21-bit) range of Unicode.
These restrictions are now documented but should be removed in a
future version, if possible.
Clarify functionality of fl_not_clipped() and fl_clip_box().
Add developer documentation for Fl_Graphics_Driver::clip_box().
Documentation only, no code changes in this commit.
This new class is explicitly internal and undocumented. We can
rename and/or redefine or extend it as we need.
This work is based on Matt's recent update with separate internal
classes BMPReader and GIFReader which have been replaced by
Fl_Image_Reader.
