Visual Studio projects that link to the FLTK DLL (fltk::fltk-shared)
inherit the compile definition set by the DLL target and will be
compiled with "-D FL_DLL" as required w/o the user project having
to set this preprocessor macro explicitly.
Todo: documentation will follow...
- remove build option FLTK_USE_KDIALOG replaced by an Fl::option() option
- new run-time option OPTION_FNFC_USES_KDIALOG
- make options OPTION_FNFC_USES_KDIALOG and OPTION_FNFC_USES_ZENITY
false by default
- add mention of new program fltk-options in the doc of Fl::option()
- change logic of choice of the native file chooser under X11/Wayland:
the zenity and kdialog choosers are opt-in; otherwise the GTK file chooser
is used, unless opted out with OPTION_FNFC_USES_GTK
- document that zenity may be interesting for sandboxed apps
- document that both zenity and kdialog make member functions
Fl_Native_File_Chooser::filter_value() inoperable
* CMake integration, no autotiools
* alignment panel is now correctly renamed to setting panel
* source view is now correctly renamed to code view
* Merge FLTK FLUID docs into FLUID user manual.
* Add two simple entry tutorials
* Remove FLUID chapter form FLTK docs.
* GitHub action to generate HTML and PDF docs and
make the available as artefacts
Parts of this commit fix the usage of CMake targets in the generation
process of fltk-config modified by PR #954.
The rest improves handling of variables used to generate fltk-config,
removes obsolete comments, documents variables like GLLIBS etc. which
had to be done anyway.
This carries include directories and the required link flags.
Several libraries brought in through pkg_check_modules aren't linked correctly using the _LDFLAGS variables.
Instead, they link the libraries directly with `-l`.
This is problematic because it doesn't properly pull in the actual directory of the library being linked when it is not in a system library directory.
Likewise, the necessary include directories for several of these targets aren't properly set either.
Linking against the imported targets automatically pulls in the necessary include directories.
* CMake: Improve detection of the GLU library and GL/glu.h header file
Locate the GLU library and header independent of the GL library and header locations.
Add the GLU header location to necessary target_include_directory calls.
* CMake: Locate and use the GL include directory
Find the GL include directory and use it in target_include_directories calls.
- simplify and unify build option output
- alignment can be changed in only 2 macros in CMake/fl_summary.cmake
- output system library location of image libraries if applicable
- it's no longer necessary to take care of the change in the layout of "struct libdecor"
between versions ≤ 0.2.2 and > 0.2.2 of libdecor
- version > 0.2.2 contains MR131, that is, it defines LIBDECOR_WINDOW_STATE_RESIZING
so the hack to emulate it is no longer necessary
- CMake option FLTK_USE_SYSTEM_LIBDECOR now requires libdecor version > 0.2.2
to be activated, otherwise the bundled libdecor is used
- what will be the libdecor version after 0.2.2 (0.2.3? 0.3.0?) is not known as of today
Too much simplified code when introducing modern CMake and renaming
some build options caused this issue. It's hopefully fixed nor, or
at least improved.
Todo: the code in question needs to be revised anyway.
fluid and fltk-options are now installed correctly as bundles and as
stand-alone executables side by side in the 'bin' folder relative
to CMAKE_INSTALL_PREFIX.
This works but the installation folders may be changed in the future.
Targets fltk::fluid is now exported correctly so
find_package(FLTK CONFIG ...)
works with both the build folder and an installed version.
Improve recognition of Wayland and X11 specific build options and
remove duplicates from required dependencies (FLTK_LDLIBS) used in
fltk-config.
This should also fix the GitLab CI build process.
To do: the logic to find the dependencies of Wayland and X11 is
currently suboptimal. This will be improved in a later commit.
This is a big commit and there are too many changes to list them all.
The main changes are:
- rename all CMake build options to 'FLTK_*'
- export library targets with namespace (prefix) 'fltk::'
- standardize shared library target names with suffix '-shared'
- set public build properties on libraries for consumers
- document library names and aliases in README.CMake.txt
- document changes in "Migrating Code from FLTK 1.3 to 1.4"
- partial backwards compatibility for old user projects
Included but not directly related changes:
- fix Windows (Visual Studio) DLL build
- add CMake function fl_debug_target() to show target properties
- don't build test programs if FLTK is a subproject
- internal: reformat CMake code: remove space before '('
Thanks to Matthias and Manolo for their help, testing, and feeback.
... with cmake_minimum_required(VERSION 3.4) or higher. This version
sets CMP0065 to 'NEW' which by default inhibits exporting global
symbols from executable programs.
For details see CMake policy CMP0065 and README.Wayland.txt.
This library is no longer needed in FLTK itself. There is only one
demo program (test/forms.cxx) that uses it if it is built. The demo
program displays a message if fltk_forms is not available.
The default is 'enabled' for backwards compatibility but this may
be changed to 'disabled' in a future version.
1. 'exec_program()' should be replaced with 'execute_process()'. Done.
2. 'cmake -E remove' is broken and deprecated since 3.17, hence we use
'cmake -E rm' (!) for CMake since 3.17 and
'cmake -E remove' only for older CMake versions.
This commit makes the default FLTK build setting use libdecor
as packaged in Linux when the build system contains packages
libdecor-0-dev and libdecor-0-plugin-1-gtk in version ≥ 0.2.0.
Otherwise, FLTK uses the bundled version of libdecor.
This includes situations where package libdecor-0-dev is
present in an earlier version.
This modifies the debug environment so demo programs linked to FLTK
DLL's can be debugged w/o copying FLTK DLL's to the build folders
of the demo programs.
This is work in progress and may be improved in a future commit but
it works as it is now for all demo programs.
- add CMake option 'OPTION_USE_STD'
- add configure option '--enable-use_std'
- move FL/Fl_String.H to src/Fl_String.H
- move FL/Fl_Int_Vector.H to src/Fl_Int_Vector.H
- remove Fl_String from demo program examples/callbacks.cxx
- remove Fl_Int_Vector from public header FL/Fl_Table.H
- some methods of Fl_Table are no longer inline
- add CMake option OPTION_USE_STD to allow std::string in some
selected functions and methods
Experimental, may be removed before release:
- use either Fl_Int_Vector or std::vector in Fl_Table depending
on CMake OPTION_USE_STD or configure --enable-use_std
Move all fl_filename* functions that use Fl_String to fluid
Main changes in fluid:
- add fluid_filename.h and .cxx
- include "fluid_filename.h" rather than <FL/filename.H>
Update fl_input(), fl_password() and test/ask
- add maxchar parameter to fl_input() and fl_password()
- fl_input_str() and fl_password_str() are optional and return
std::string if enabled (FLTK_USE_STD)
... so they are not inherited by consumers of the library.
Remove 'add_definitions(-DFL_LIBRARY)' from src/CMakeLists.txt
This is not necessary, see CMake/fl_add_library.cmake
Don't set obsolete property 'CLEAN_DIRECT_OUTPUT' which was removed
in CMake 2.8.0.
- remove separate libfltk_cairo to avoid cyclic dependencies, but
- keep a dummy libfltk_cairo in 1.4.0 for backwards compatibility
- move cairo/Fl_Cairo.cxx to src/Fl_Cairo.cxx
- add preliminary Cairo support for Visual Studio (MSVC)
Static linking is not affected by this change, but users building
with hand-made Makefiles will have to remove libfltk_cairo starting
with FLTK 1.4.0. The dummy library can be linked for backwards
compatibility but it will be removed later (in 1.4.x or 1.5.0).
The shared FLTK library libfltk.{so|dylib|dll|..} depends on libcairo
if and only if FLTK is built with one of the Cairo options. This has
always been the case for OPTION_CAIROEXT but is now also true if only
OPTION_CAIRO is selected, i.e. FLTK programs linked with a Cairo
enabled shared FLTK library will also be linked with libcairo. The same
is true for configure options --enable-cairo and --enable-cairoext,
respectively.
Preliminary Cairo support for MSVC now detects a Cairo installation
using the CMake variable FLTK_CAIRO_DIR which must be set by the user.
Note that this feature is temporary and may be changed in the future
for a better and more comfortable version.
CMake only: replace wrong variable names with correct ones. Affected
were all image libraries (jpeg, png) and zlib.
These variables had been renamed in an earlier commit when lots of
CMake code had been rewritten.
If available, it is used on Linux regardless of the current desktop because
it offers free XDG portal integration, which means it picks the correct file
chooser on all desktops, and allows for meaningful file selection in sandbox
environments like Flatpak.
This removes the cause of this developer's message
# FIXME: This needs to be redesigned! Forcing GTK_FOUND to 0 (NO) is a bad
# FIXME: idea because there could be unwanted side effects. AlbrechtS
These option combinations work:
-DOPTION_APPLE_X11
-DOPTION_APPLE_X11 -DOPTION_USE_CAIRO
But
-DOPTION_APPLE_X11 -DOPTION_USE_PANGO
is not possible because homebrew doesn't provide the pangoxft package.
This is only one minor step to remove issues of some CMake options
that can cause conflicting include directories ("-I..." switches).
See implementation note in CMake/options.cmake.
This variable has never been used in the code. Configure and CMake
look for a *working* libpng (HAVE_PNG) and set variable HAVE_PNG_H
if the header <png.h> can be included.
The alternative to include <libpng/png.h> is always used in the #else
clause and doesn't need its own config variable. Configure and CMake
log what they find, hence this extra variable is not necessary.
On Windows fluid.exe is a "GUI" program and does not allow console
output which can be a problem in automated builds. In Visual Studio
the fluid GUI program would pop up console windows when generating
.cxx and .h files from .fl files.
The new (additional) fluid-cmd.exe is built as console application
for users that need it and it is used in the FLTK build process on
Windows to convert the .fl files.
I decided not to install the man pages for consistency because we
don't install the executable programs. The instructions are commented
out only so they can be activated easily if this will be changed,
i.e. if we decide to install the test/game programs in the future.
Closes#23
The intended effect (building a Windows "GUI" application), is
correctly achieved using the "WIN32" option of add_executable()
selectively where appropriate rather than setting this platform
specific option for *all* (Windows) executables when using GNU
compilers (MinGW, MSYS2, Cygwin, ...).
According to PR #415 this switch was added in Visual Studio 2015
Update 3. However, version "1900" does not distinguish updates,
hence Visual Studio 2015 up to Update 2 may fail to compile with
this addition. Installing the updates would obviously fix this.
The source files are all encoded by UTF-8 without BOM. This will raise
warnings and errors when compiling by the MSVC with some active code
pages (ACP). The file `test/ask.cxx` contains such characters with UTF-8
encoding. Adding `/utf-8` here is equivalent to specifying
`/source-charset:utf-8 /execution-charset:utf-8`, and all warnings and
errors are removed.
Although CMake uses previously undefined variables like empty strings
it could happen that variables set in the calling context by other
projects initialized some variables with unexpected values.
Example: FLTK_LIBRARIES could have been initialized by previous
execution of 'find_package(FLTK ...)' in a project using FLTK
- set executable permissions on MinGW and more platforms
- add missing link libraries
- improve code formatting (indent)
- mark some variables as advanced
- simplify search for glib-2.0
The Visual Studio generator does often not find GL/glu.h and locale.h
although these headers are in the Visual Studio SDK. The warning has
been changed to "info" and the unnecessary and sometimes confusing
recommendation to rerun CMake has been removed.
fl_debug_pkg(...) can be used to display CMake variables set by
executing pkg_check_modules(). This is for CMake debugging only.
The CMake configuration summary displays configuration options
of Wayland, Pango, Xft, and Cairo configuration.
If a user project is built using a FLTK library generated by CMake
with Cairo support then the CMake variable FLTK_INCLUDE_DIRECTORIES
now includes the required Cairo include directories.
... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0
Use of the kdialog command by class Fl_Naive_File_Chooser can now be turned off
at build-time through CMake OPTION_USE_KDIALOG.
If building via configure + make, set #define USE_KDIALOG to 0 in config.h before make.
CMake/compatibility.cmake: define functions and macros to be used
if a particular CMake functionality requires a higher CMake version
than FLTK's minimum CMake version, see 'cmake_minimum_required(...)'
in the root CMakeLists.txt.
Note: target_link_directories() is available since CMake 3.13
Add CMake test for PTHREAD_MUTEX_RECURSIVE
Add autoconf/configure compile test for PTHREAD_MUTEX_RECURSIVE
Replace "#ifdef PTHREAD_MUTEX_RECURSIVE"
with "#ifdef HAVE_PTHREAD_MUTEX_RECURSIVE"
and define HAVE_PTHREAD_MUTEX_RECURSIVE in config.h
