Fl_Group::clear() is called in Fl_Group's d'tor anyway.
Technically we don't need to remove hscrollbar and scrollbar because
they are destroyed (and thus removed from Fl_Group) before Fl_Group's
d'tor is executed but this is left for clarity and to guarantee the
order (see comment).
It notably honors SOURCE_DATE_EPOCH if set, making for reproducible
output. For even better reproducibility, use UTC. (Unlike the date
command's output, the result is already always in English.) Extend
this approach to the book, introducing appropriately formatted
PDF_DATE and TODAY variables for its PDF metadata and title page
respectively and making make_pdf configurable.
Debug only, if fl_debug_target() is used:
Prior to CMake 3.19 some properties of "INTERFACE_LIBRARY targets"
can't be read with get_property(). These properties are now
excluded if the CMake version is lower than 3.19.
... so users can enable ABI features designated for the *next* release
when using FLTK from Git (or snapshots) before the API version has
been raised for that release.
Rationale:
1. Building in-source creates a lot of untracked files in the source
tree. We need to take care not to commit any of them, hence we
have to maintain .gitignore files in several directories.
2. Tests reveal that there are even files in git that are modified
in the source tree when building docs etc. which means e.g.
that builds can't be "repeated" after upgrading the sources, and
that those files could be committed by accident. To avoid this
we'd have to reorganize the build procedure and make it even more
complex rather than simplifying it.
3. With autoconf/configure/make we didn't have a choice, i.e. we had
to allow in-source builds with configure/Makefiles anyway. This
is no longer true since we removed configure/make support.
Note, todo: if this commit doesn't introduce unexpected issues, then
we can remove a lot of stuff from the .gitignore files, but this
is left for a later commit.
For details please see description in the source code in
test/checkers.cxx lines 620++
This commit also disables unused code: function dumpnode() which is
used only in VT100 mode.
Calling getenv() twice with different output vars and accessing both
later could cause "heap-use-after-free" error in some Windows versions.
The result of home_directory_name() would be unpredictable.

* Add classes for application and project
* Removed all globals from Fluid.h
* Extracting args and project history into their own classes
* Moving globals into Application class
* Initialize values inside headers for some classes.
* Undo functionality wrapped in a class inside Project.
* File reader and writer are now linked to a project.
* Avoid global project access
* Nodes (former Types) will be managed by a new Tree class.
* Removed static members (hidden globals) form Node/Fl_Type.
* Adding Tree iterator.
* Use nullptr instead of 0, NULL, or 0L
* Renamed Fl_..._Type to ..._Node, FL_OVERRIDE -> override
* Renaming ..._type to ...::prototype
* Splitting Widget Panel into multiple files.
* Moved callback code into widget panel file.
* Cleaning up Fluid_Image -> Image_asset
* Moving Fd_Snap_Action into new namespace fld::app::Snap_Action etc.
* Moved mergeback into proj folder.
* `enum ID` is now `enum class Type`.
This commit is bigger than necessary to fix the buffer allocation but
it also prevents some unnecessary string copies: the font name is
converted from UTF-16 to UTF-8 directly in the buffer used later.
Code reformatted and clarified as well, some duplicated code was
removed.
CMake/fl_add_library.cmake: set target_compile_features(.. cxx_std_NN)
which is inherited by consumers of the library.
This prevents CMake user projects from failing if they would
otherwise compile with an older C++ standard.
CMake/fl_debug_var.cmake: add INTERFACE_COMPILE_FEATURES to fl_debug_target()
CMake/fl_summary.cmake: update summary format for longer variable names
CMakeLists.txt:
- check CMAKE_CXX_STANDARD given by the user (commandline)
and set C++ standard related CMake variables in the CMake cache.
The latter is experimental: setting in the cache may be reverted.
- add C++ standard related info to configure summary.
This is the main README file on GitHub. It is similar to README.txt
but doesn't contain every detail to keep it somewhat shorter but
still informative.
The "badges" at the end show details about GitHub Actions (CI).
All files: remove autoconf/configure related stuff, update links.
- README.txt: describe prerequisites, provide generic instructions
on how to use CMake to build FLTK
- test/demo.cxx: remove code used for configure/make build
- test/CMakeLists.txt: remove obsolete 'target_compile_definitions()'
A problem was visible with the menubar test app and a 2-screen system where screens are one above the other.
When moving down the huge menu, it became positioned on the wrong screen.
