Changes in FLTK 1.4.0 Released: ??? ?? 2017
General Information about this Release
- FLTK 1.4.0 is based on FLTK 1.3.4 (released Nov 15 2016),
see CHANGES_1.3 for more information.
- CMake is the primary supported build system in FLTK 1.4.0 and later.
CMake can be used to generate Makefiles, IDE project files, and
several other build systems by using different "generators" provided
by CMake (for instance Ninja, CodeBlocks, Eclipse, KDevelop3, Xcode, etc.).
See README.CMake.txt for more information.
- autoconf/configure is still supported by the FLTK team for backwards
compatibility with older systems that lack CMake support.
New Features and Extensions
- (add new items here)
- New Fl_SVG_Image class: gives support of scalable vector graphics images
to FLTK using the nanosvg software.
- Fl_Text_Selection got a new method length() and returns 0 in length()
and in all offsets (start(), end(), position()) if no text is selected
(selected() == false). The behavior in FLTK 1.3 and earlier versions
(returning undefined values if !selected()) was confusing.
- Added support for MacOS 10.13 "High Sierra".
- New method Fl_Group::bounds() replaces Fl_Group::sizes() which is now
deprecated. Fl_Group::bounds() uses the new class Fl_Rect that contains
widget coordinates and sizes x(), y(), w(), and h() (STR #3385).
Documentation for bounds() and its internal structure was added.
- X11 platform: Added support for HiDPI displays and for rescaling any window
at run-time under user control. Under the gnome desktop, FLTK applications
detect the current gnome scaling factor and use it to scale all FLTK windows.
Under other desktops, the FLTK_SCALING_FACTOR environment variable can be
used to set the starting scaling factor of all FLTK applications.
In addition, it is possible to rescale all FLTK windows mapped to a screen
by typing ctrl-'+' (enlarge), ctrl-'-' (shrink) or ctrl-'0' (back to starting
factor value). Windows moved between screens adjust to the scaling factor of
their screen. This supports desktops mixing screens with distinct resolutions.
[HiDPI displays have been supported since FLTK 1.3.3 for the WIN32 and MacOS platforms].
- New method shadow(int) allows to disable the shadows of the hands
of Fl_Clock, Fl_Clock_Output, and derived widgets.
- New method Fl_Tabs::tab_align() allows to set alignment of tab labels,
particularly to support icons on tab labels (STR #3076).
- Added '--enable-print' option to configure effective under X11 platforms
and with 'yes' default value. Using '--enable-print=no' removes print
and PostScript support from the FLTK library, thus reducing its size.
- Added Fl_Surface_Device::push_current(new_surface) and
Fl_Surface_Device::pop_current() to set/unset the current surface
receiving graphics commands.
- X11 platform: Added support for drawing text with the pango library
which allows to draw most scripts supported by Unicode, including CJK
and right-to-left scripts. The corresponding CMake option is
OPTION_USE_PANGO. The corresponding configure option is --enable-pango.
This option is OFF by default.
New Configuration Options (ABI Version)
- The library can be built without support for SVG images using the
--disable-nanosvg configure option or turning off OPTION_USE_NANOSVG in CMake.
- FLTK's ABI version can be configured with 'configure' and CMake.
See documentation in README.abi-version.txt.
1.4.0 ABI FEATURES
- None. FLTK 1.4.0 has a new ABI, breaking 1.3.x ABI.
Other Improvements
- (add new items here)
- The Fl_Boxtype and Fl_Labeltype definitions contained enum values
(names) with a leading underscore (e.g. _FL_MULTI_LABEL) that had to
be used in this form. Now all boxtypes and labeltypes can and should
be used without the leading underscore. A note was added to the enum
documentations to make clear that the leading underscore must not be
used in user code, although the enum documentation still contains
leading underscores for technical reasons (internal use).
- The blocks demo program got a new keyboard shortcut (ALT+SHIFT+H) to
reset the user's high score. It is now slower than before in higher
levels, hence you can expect higher scores (due to a bug fix in the
timer code). You can use the '+' key to increase the level at all times.
- Some methods of Fl_Tabs are now virtual and/or protected for easier
subclassing without code duplication (STR #3211 and others).
To be continued...
- Separated Fl_Input_Choice.H and Fl_Input_Choice.cxx (STR #2750, #2752).
- Separated Fl_Spinner.H and Fl_Spinner.cxx (STR #2776).
- New method Fl_Spinner::wrap(int) allows to set wrap mode at bounds if
value is changed by pressing or holding one of the buttons (STR #3365).
- Fl_Spinner now handles Up and Down keys when the input field has
keyboard focus (STR #2989).
- Renamed test/help.cxx demo program to test/help_dialog.cxx to avoid
name conflict with CMake's auto-generated target 'help'.
- Many documentation fixes, clarifications, and enhancements.
Bug Fixes
- (add new items here)
- Fix Fl_PNG_Image error handling. An error was potentially caused
by error handling of the image library with setjmp/longjmp.
- Fix Fl_Browser background and text color parsing (STR #3376).
- Fix Windows CreateDC/DeleteDC mismatch (STR #3373).
- Fix Fl_Tabs label drawing for Fl_Window children (STR #3075).
- Fix line number alignment in Fl_Text_Display/Editor (STR #3363).
- Fix ignored buffer pre-allocation (requestedSize) in Fl_Text_Buffer.
See fltk.general "Fl_Text_Buffer constructor bug" on Dec 5, 2016.
- Fix build with configure --enable-cairo --enable-cairoext,
see this report in fltk.general:

Removed Features
- Bundled IDE project files (Xcode and Visual Studio) have been
removed. Please use CMake to generate your IDE project files.
