We need to get the error message in "wide character" format and
convert it to UTF-8. The conversion would truncate it if the
buffer was too small, hence we don't need to check for overflow.
Tested on Windows 10 with VS 2010, including (faked) error codes with
non-ASCII characters (German).

This change ensures errors in local language.
See issue #99 for discussion on why this is needed.

strerror_r() sounds like the better thing to use, but if you
read the man page carefully, there are pitfalls of competing
GNU vs POSIX versions of the same function, with different
return values.
GNU version returns a pointer to the error string, which may
or may not use the error string supplied to use. Makes no sense.
Why not use the buffer the user prepared? Makes returning errors hard.
One thing GNU does underline is the string is always NUL terminated.
POSIX version doesn't return a string at all, it returns an int,
making handling the GNU cases impossible. POSIX /doesn't/ say
one way or the other about the string being NUL terminated, so
you have to make sure when you use it.
I trawled the net, seems this is a big annoying issue.
For now, leaving the code with strerror(), but we should change it.

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()

add resize chapter to documentation, plus images,
based on Article #415: How does resizing work?

Also small but unnecessary code change to reset row_edit/col
to zero after editing for example clarity.
Unnecessary b/c those vars are ignored anyway when input
visibility turned off, so change is more cosmetic codewise.

Fluid would write trailing whitespace at some points when generating
.cxx and .h files from .fl files.
This was an old issue but became obvious since we removed trailing
whitespace from source and header files recently.
This commit fixes all whitespace errors in files generated from .fl
files in the FLTK repository, i.e. in fluid/, src/, and test/ folders.
I can't guarantee that I found all possible whitespace errors, but
this commit:
Fixes #100

A user was having trouble figuring this out on fltk.general,
seemed like a tooltip could have helped, so added it.

- 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.

Make clear that Fl::repeat_timeout() must only be called for the
same timeout it is handling. Related STR's:

File examples/SVG_File_Surface.cxx is no longer useful because it was a very
partial implementation of what is now class Fl_SVG_File_Surface.
|
|
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.
|
|
These files can be compiled-in for other architectures but produce no binary code.
|
|
Note: there's more to do ...
|
|
- fix typos and minor, obvious errors
- reformat small parts
- remove trailing whitespace

As documented, Fl::next_window(win) must only be called with a valid
*shown* window. The old code would crash if the argument was NULL
or the window was not shown.
The new code avoids the crash, issues an error message, and returns
NULL to the caller.

Commit 6fe226cb804d000b29ea53e08acc505267fd44de introduced use of
pkg-config which broke linking from fltk-config if FLTK was
configured to use pango library.
This patch duplicates line from another if branch that just adds
libraries assuming that if pkg-config found pangoxft that there
are present all it's requirements.

Some of the test programs were linked with libfltk_forms which was
unnecessary. The only one requiring this is the forms demo.
[CMake] reordered linked FLTK libs in dependency order.

Had to get away from overloading PIDs with error codes,
so now error codes are returned separately from the PID.

Fix for issue #90: Setting an svg image as a window icon causes a segfault.

If a user program accidentally deletes the "current" group, then
the pointer would still point at the deleted widget. This commit
prevents this and makes the Fl_Group's parent the current group.
Fixes issue #88.

Clean up library and variable names.
Remove '_SHARED' suffix from library (output) filenames.
This commit was inspired by David Runge ('dvzrv'), thanks.
See PR #21.

Cherry-pick the essential changes from FLTK 1.3 since this change
had not been ported to 1.4 yet.
To do: my current plan is to consolidate 1.3 and 1.4 CMake files
as far as possible (with the exceptions of source files, obviously)
and to redesign / refactor CMake files later in this process or
maybe only for 1.4 if it turns out to be too much to backport.

We use the host system's `fluid` when cross-compiling. This must be
executable as `fluid`, i.e. it must be in the PATH or otherwise
defined, for instance as an alias.

- 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.

Thanks to the OP for most of the fix.

The "Visual Studio Code" editor (Open Source by Microsoft) is
becoming more and more popular. It uses a (hidden) folder '.vscode'
in the workspace root directory to store its configurations. We
need to ignore this folder to avoid confusing developers and
checking it in by accident.

The new window callback demonstrates how to close all (both) windows

That may be necessary if preferences are accessed before fl_open_display() was called.
