|
Changes in FLTK 1.4.0 RC1 Released: Oct 20 2024 |
|
|
|
General Information about this Release |
|
|
|
- FLTK 1.4.0 is based on FLTK 1.3.4 (released Nov 15 2016). |
|
Later updates have partially been backported to 1.3.x releases, see |
|
CHANGES_1.3.txt 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 files |
|
for several other build systems by using different "generators" provided |
|
by CMake (for instance Ninja, CodeBlocks, Eclipse, KDevelop3, Xcode, etc.). |
|
FLTK uses "Modern CMake" since release 1.4.0 which simplifies user |
|
project build systems significantly. |
|
See README.CMake.txt and documentation chapter "Migrating Code from |
|
FLTK 1.3 to 1.4" for more information. |
|
|
|
- autoconf/configure is still supported by the FLTK Team for backwards |
|
compatibility with older systems that lack CMake support. Support of |
|
autoconf/configure will be dropped in FLTK 1.5.0. |
|
|
|
- FLTK 1.4 introduces a new platform, Wayland, available for recent Linux |
|
distributions and FreeBSD. For details see README.Wayland.txt. |
|
|
|
New Features and Extensions |
|
|
|
- fltk-config allows to compile multiple files with more compiler and linker |
|
options given on the commandline. |
|
- fl_contrast() functionality has been improved, adding a new contrast |
|
calculation method based on human contrast perception. This new function |
|
is now the default but the old, less accurate, contrast function can be |
|
chosen as an option. |
|
- Timeout handling has been unified across platforms (#379), see documentation |
|
in chapter "Migrating Code from FLTK 1.3 to 1.4". |
|
- New Fl::remove_next_timeout(...) to remove only one timeout (#992). |
|
- New fltk-options executable, improved Fl::option documentation. |
|
- New function `Fl_Window::get_size_range()` (#981). |
|
- New FL_DEPRECATED macro to flag deprecated functions and methods. |
|
- Enable suppression of "deprecated" warnings by macro FL_NO_DEPRECATE. |
|
- New animated GIF images support (Fl_Anim_GIF_Image class) (#375). |
|
- GIF and BMP files can now be "read" from memory, i.e. they can be included |
|
in source code (use their new constructors). |
|
- New Fl_Scheme_Choice widget can be used to easily switch schemes in apps. |
|
- A new scheme named "oxy" has been added (STR 2675, STR 3477). |
|
- Drawing "Arrows" has been unified in all core widgets. |
|
- Drawing "Radio Buttons" has been unified in all core widgets. |
|
- Drawing "Check Marks" has been unified in all core widgets. |
|
- New methods Fl_Group::on_insert/on_remove/on_move (#527) can be used in |
|
derived classes to detect addition or removal of children. |
|
- FLTK widgets can now be used in OpenGL 3 windows. |
|
- The new convenience function Fl::hide_all_windows() can be used to close |
|
all open windows, for instance to exit the running program. |
|
- Windows platform: optionally use GDI+ to antialias oblique lines and curves. |
|
- Windows: The new function Fl::args_to_utf8() can be used to convert |
|
"wide character" commandline arguments to UTF-8. |
|
- X11 and Wayland platforms: Added support of HiDPI displays. FLTK apps |
|
detect the current display scaling factor and use it to scale all windows. |
|
- Windows platform: FLTK applications detect the display scaling factor and |
|
automatically scale their GUI accordingly. This effectively renders WIN32 |
|
FLTK apps "per-monitor DPI-aware" whereas they were "DPI-unaware" before. |
|
- Dynamical GUI rescaling: it is possible on all platforms to rescale all |
|
FLTK windows mapped to a screen by typing ctrl-'+' (enlarge), ctrl-'-' |
|
(shrink) or ctrl-'0' (back to starting scaling factor value). Under macOS, |
|
the corresponding keystrokes are cmd-'+', cmd-'-', cmd-'0'. The resulting |
|
GUI scaling factor (e.g., 170 %) transiently appears in a yellow popup window. |
|
Use new Fl::option() item OPTION_SHOW_SCALING to turn on/off these popups. |
|
Windows moved between screens adjust to the scaling factor of their screen. |
|
This supports desktops mixing screens with distinct resolutions. |
|
In addition, use environment variable FLTK_SCALING_FACTOR to further adjust |
|
the starting scaling factor of all FLTK apps. |
|
- Note: On some platforms and with some international keyboard layouts you may |
|
need to set Fl::option(OPTION_SIMPLE_ZOOM_SHORTCUT) to be able to use one or |
|
more of the scaling shortcuts above with or without pressing the Shift key. |
|
The new executable `fltk-options` can be used to set this option either |
|
system wide or for a single user. |
|
- New horizontal and vertical label margins. |
|
- Fluid got a lot of UI and functional improvements and the Fluid docs have |
|
been reworked and put in an own "Fluid User Manual" (HTML and PDF). |
|
Fluid supports the new Fl_Flex and Fl_Grid widgets. |
|
For more details please see the manual. |
|
- New Fl_Grid class to layout multiple columns and rows of widgets. |
|
- New Fl_Flex class to layout one row or one column of widgets. |
|
- New Fl_Terminal widget supporting Unicode/UTF-8, ANSI/xterm escape codes |
|
with full RGB color control. |
|
- New Fl_Copy_Surface to copy drawings to the clipboard. |
|
- New Fl::keyboard_screen_scaling(0) call stops recognition of ctrl/+/-/0/ |
|
keystrokes as scaling all windows of a screen. |
|
- New member function Fl_Image::scale(int width, int height) to set |
|
the drawing size of an image independently from its data size. The |
|
same function was previously available only for class Fl_Shared_Image |
|
and with FL_ABI_VERSION >= 10304. New member functions Fl_Image::data_w() |
|
and Fl_Image::data_h() give the width and height of the image data. |
|
- New member functions Fl_Widget::bind_image(Fl_Image *img) and |
|
Fl_Widget::bind_deimage(Fl_Image *img) to bind an image to a widget, that is, |
|
to set an image to be used as part of the widget label and also |
|
to be deleted when the widget is deleted. |
|
- New member function Fl_Menu_::menu_end() to ensure that the menu is fully |
|
constructed in its final location after dynamic modifications. This is |
|
called automatically before the menu is shown. |
|
- New Fl_SVG_Image class: gives support of scalable vector graphics images |
|
to FLTK using the nanosvg software. |
|
- New Fl_ICO_Image class to read Windows .ico icon files. |
|
- New classes Fl_PDF_File_Surface, Fl_SVG_File_Surface and Fl_EPS_File_Surface |
|
to save any FLTK graphics to PDF, SVG or EPS files, respectively. |
|
- New member functions Fl_Window::maximize(), Fl_Window::un_maximize() and |
|
Fl_Window::maximize_active() to programmatically manage window maximization. |
|
- Fl_Button now supports a compact flag that visually groups closely set |
|
buttons into keypads. |
|
- Fl_Tabs widget now supports close buttons for individual tabs. |
|
- Fl_Tabs widget now supports four different modes for handling an |
|
overflowing number of tabs. |
|
- Mouse buttons 4 + 5 (aka "side buttons") are now supported (#1076, #1068). |
|
These are typically used as "back" and "forward" functions, e.g. in browsers. |
|
- Windows platform: added support for using a manifest to set the |
|
application's level of DPI awareness (issue #309). |
|
- class Fl_Native_File_Chooser on the X11/Wayland platform relies on external |
|
commands zenity (PR #599), or kdialog (issue #278), or on the GTK library |
|
to construct file dialogs. New "Preview" switch added to the GTK dialog. |
|
The libgtk-based dialog uses in priority the file chooser dialog |
|
of GTK version 3 when available on the running platform, and falls back |
|
to version 2 when V3 is not available. In contrast, GTK version 2 was used |
|
in priority by FLTK 1.3.x. New FL::option() item OPTION_FNFC_USES_ZENITY |
|
to turn on/off use of zenity-based file dialogs. |
|
- The undocumented feature FLTK_CONSOLIDATE_MOTION is now OFF on X11 and |
|
removed on macOS. In FLTK 1.3 this feature has been ON on X11. The macro can now |
|
be set on the compiler commandline and can be used to reduce the number |
|
of mouse move events sent to the application but it may be unreliable. |
|
Recommendation: let it switched OFF unless you really need it. |
|
- New function fl_capture_window() to capture the content of a rectangular |
|
zone of a mapped window and return it as an Fl_RGB_Image. It improves |
|
with HighDPI displays what can be done with fl_read_image(). |
|
- The Windows platform now draws oblique and curved lines in antialiased |
|
form. The new function void fl_antialias(int state); allows to turn off |
|
or on such antialiased drawing. The new function int fl_antialias(); returns |
|
whether line and curve drawing is currently antialiased. |
|
- The border radius of "rounded" box types can be limited and |
|
the shadow width of "shadow" box types can be configured (issue #130). |
|
See Fl::box_border_radius_max() and Fl::box_shadow_width(). |
|
- New fl_putenv() is a cross-platform putenv() wrapper (see docs). |
|
- New public variable Fl_Image::register_images_done allows an app. to detect |
|
whether function fl_register_images() has been called. |
|
- Fix Fl::add_timeout() under Linux (STR 3516). |
|
- Fix early timeouts in Fl_Clock seen in some environments (STR 3516). |
|
- Fl_Printer::begin_job() uses by default the Gnome print dialog on the X11 |
|
platform when the GTK library is available at run-time. That can be turned off |
|
with Fl::option(OPTION_PRINTER_USES_GTK, false). |
|
- New member functions Fl_Paged_Device::begin_job() and begin_page() |
|
replace start_job() and start_page(). The start_... names are maintained |
|
for API compatibility. |
|
- Fl_Gl_Window can now contain FLTK widgets that are drawn on top of the |
|
OpenGL scene. |
|
- OpenGL draws text using textures on all platforms, when the necessary |
|
hardware support is present (a backup mechanism is available in absence |
|
of this support). Thus, all text drawable in Fl_Window's can be drawn |
|
in Fl_Gl_Window's (STR#3450). |
|
- New member function Fl_Menu_Bar::play_menu(const char *title) to |
|
programmatically open a menu of a menubar. |
|
- New member functions Fl::program_should_quit(void), |
|
and Fl::program_should_quit(int) to support detection by the library |
|
of a request to terminate cleanly the program. |
|
- MacOS platform: the processing of the application menu's "Quit" item |
|
has been changed. With FLTK 1.3.x, the application terminated when all |
|
windows were closed even before Fl::run() or Fl::wait() could return. |
|
With FLTK 1.4, Fl::run() returns so the app follows its normal termination path. |
|
- FLTK apps on the MacOS platform contain automatically a Window menu, which, |
|
under MacOS ≥ 10.12, allows to group/ungroup windows in tabbed form. The new |
|
Fl_Sys_Menu_Bar::window_menu_style() function allows to specify various |
|
styles for the Window menu, even not to create it. |
|
- New function: int fl_open_ext(const char* fname, int binary, int oflags, ...) |
|
to control the opening of files in binary/text mode in a cross-platform way. |
|
- Fix for issue #247 : loading SVG image with BOM. |
|
- 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. |
|
- 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. |
|
- 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 Fl_Surface_Device::push_current(new_surface) and |
|
Fl_Surface_Device::pop_current() to set/unset the current surface |
|
receiving graphics commands. |
|
- New macros for easy function and method callbacks with multiple |
|
type safe arguments (see FL_METHOD_CALLBACK_1 etc.) . |
|
- The value box size of Fl_Value_Slider is now user settable (STR 3222). |
|
- The new header file FL/fl_config.h replaces FL/abi-version.h and |
|
includes some more build configuration settings. This file is always |
|
included automatically. |
|
- Nested (aka recursive) common dialogs are now possible (STR 3242, #282). |
|
|
|
Removed Features |
|
|
|
- X11 platform: Support of XDBE, the configure option '--enable-xdbe' |
|
and the CMake option 'OPTION_USE_XDBE' have been removed because XDBE |
|
was unreliable and rarely supported by X servers. Double buffering |
|
support in Fl_Double_Window is not affected. |
|
- Hardware "overlay" support has been removed. This was rarely implemented |
|
and should not affect user code because overlay support is simulated. |
|
|
|
New Configuration Options (ABI Version) |
|
|
|
- Add --without-fluid configure option (#725) if Fluid is not needed. |
|
- 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. FLTK now outputs PostScript that draws |
|
those scripts in vectorial form. The corresponding CMake option is |
|
FLTK_USE_PANGO. The corresponding configure option is --enable-pango. |
|
This option is OFF by default when the build is only for X11 and ON |
|
when Wayland support is built as well. |
|
- Configure option --enable-wayland allows to build the FLTK library for |
|
the new Wayland platform while remaining compatible with X11. The |
|
corresponding CMake option is FLTK_BACKEND_WAYLAND. This option is ON by default. |
|
- Configure options --enable-wayland --disable-x11 used together allow to |
|
build FLTK for the Wayland backend only (no x11 backend). Under CMake, the |
|
equivalent option is to set FLTK_BACKEND_WAYLAND=ON and FLTK_BACKEND_X11=OFF. |
|
- The new configure option --disable-gdiplus removes the possibility to draw |
|
antialiased lines and curves on the Windows platform. The corresponding CMake |
|
option is FLTK_GRAPHICS_GDIPLUS. |
|
- The library can be built without support for reading SVG images or writing |
|
graphics in SVG format using the --disable-svg configure option |
|
or turning off FLTK_OPTION_SVG in CMake. |
|
- The library can be built without support for PostScript, thus reducing |
|
its size, using the --disable-print configure option or turning off |
|
FLTK_OPTION_PRINT_SUPPORT in CMake. That makes classes Fl_PostScript_File_Device, |
|
Fl_EPS_File_Surface and Fl_Printer (under X11 platform only) ineffective. |
|
- FLTK's ABI version can be configured with 'configure' and CMake. |
|
See documentation in README.abi-version.txt. |
|
- Building the 'Forms' compatibility library 'fltk_forms' is now optional, |
|
default is ON. This may be turned to OFF in a later FLTK release. |
|
- CMake/Windows/MSVC: New option to select MSVC Runtime when linking apps. |
|
|
|
Bundled libraries |
|
|
|
- Bundled image libraries have been upgraded to newer versions. |
|
For details see documentation/src/bundled-libs.dox or online docs. |
|
|
|
1.4.0 ABI FEATURES |
|
|
|
- None. FLTK 1.4.0 has a new ABI, breaking 1.3.x ABI. |
|
|
|
|
|
Other Improvements |
|
|
|
- Fl_Image::copy() is now 'const', including all derived classes. |
|
Note: This may require code changes in classes derived from Fl_Image, |
|
see documentation in chapter "Migrating Code from FLTK 1.3 to 1.4". |
|
- Fl_Native_File_Chooser can now use kdialog, zenity, and/or GTK3 native |
|
file choosers on Linux. |
|
- Contrast of check marks and radio buttons has been improved (#443). |
|
- Improve X11 (16-bit) clipping of lines and rectangles. |
|
- Added support of macOS 15.0 "Sequoia", 14.0 "Sonoma", |
|
13.0 "Ventura", 12.0 "Monterey", and 11.0 "Big Sur". |
|
- Added macOS support for the arm64 architecture since 11.0 (Big Sur). |
|
- Added support for macOS 10.15 "Catalina" |
|
- Added support for macOS 10.14 "Mojave": all drawing to windows is done |
|
through "layer-backed views" when the app is linked to SDK 10.14. |
|
- Added support for macOS 10.13 "High Sierra". |
|
- Fixed X11 Input Method window badly positioned with Fl_Text_Editor |
|
widget (issue #270). |
|
- Fixed X11 copy-paste and drag-and-drop target selection (issue #182). |
|
This fix has been backported to 1.3.6 as well. |
|
- The user can now copy standard dialog text to the clipboard by |
|
hitting Ctrl/C (#388). |
|
- The selected color in Fl_Color_Chooser can now be copied to the |
|
clipboard by hitting Ctrl/C. |
|
- Add optional argument to Fl_Printer::begin_job() to receive |
|
a string describing the error when an error occurs. |
|
- Fix Windows-specific bug when the program tries to enlarge a |
|
maximized window, that would freeze the window (git issue #65). |
|
- Improve X11 16-bit coordinate clipping for text (STR 2798). This |
|
assumes that text is "small" WRT 16-bit coordinate space and clips |
|
text if at least one of the x/y coordinates is out of bounds. |
|
- Fix Fl::add_timeout() in draw() under Linux (STR 3188) |
|
- Improved documentation for '@' symbols in labels (STR #2940). |
|
- Fl_Roller can now be controlled via the mouse wheel (STR #3120). |
|
- Handle Shift + mousewheel event as horizontal scrolling (STR 3521). |
|
- Tooltips hide by themselves after 12 seconds (STR #2584). |
|
- Improved constructor for creating Fl_Preferences files with flags for the |
|
correct locale and for overwriting existing files. |
|
- Added Fl_Input_::append() method (STR #2953). |
|
- Fix for STR#3473 (and its duplicate STR#3507) to restore configure-based |
|
builds on recent Linux/Unix distributions where the freetype-config |
|
command has been replaced by pkg-config. |
|
- MacOS ≥ 10.10: Fl_Window::fullscreen() and fullscreen_off() no longer |
|
proceed by Fl_Window::hide() + Fl_Window::show() but essentially |
|
resize the window, as done on the X11+EWMH and Windows platforms. |
|
- Fl_Cairo_Window constructors are now compatible with Fl_Double_Window |
|
constructors - fixed missing constructors (STR #3160). |
|
- The include file for platform specific functions and definitions |
|
(FL/x.H) has been replaced with FL/platform.H. FL/x.H is deprecated |
|
but still available for backwards compatibility (STR #3435). |
|
FL/x.H will be removed in a (not yet specified) future FLTK release. |
|
We recommend to change your #include statements accordingly. |
|
- 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). |
|
- Boxtypes can now be configured to draw their own custom focus box. |
|
- 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). |
|
- Fl_Tabs now has an option to delete tabs by the user (UI), and tab |
|
overflow has been largely improved with several options. |
|
- glutAddMenuEntry() now has a *const* label argument (STR #3323) |
|
- 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'. |
|
- Fl_Menu_Bar: left and right arrow keys now wrap to the menu at the |
|
other end of the menubar when pressed in the first (resp. last) menu. |
|
- Previously "public" members Fl::awake_ring_*_ are now "private" (#559). |
|
- The test/clipboard demo program can now save PNG images. |
|
- New virtual int Fl_Group::delete_child(int n) (STR 3218). |
|
- Many documentation fixes, clarifications, and enhancements. |
|

Removed Features |
|
|
|
- Bundled IDE project files (Xcode and Visual Studio) have been |
|
removed. Please use CMake to generate your IDE project files. |
|
See README.CMake.txt for more information. |
|
- Dropped FLTK 1.0 compatibility (macro FLTK_1_0_COMPAT). This "feature" |
|
was no longer usable since FLTK 1.3, hence it can be dropped safely. |
