CHANGES IN FLTK 1.3.5 RELEASED: Mar 03 2019
Bug fixes and other improvements
- Updated CHANGES for release, removed one wrong entry
CHANGES IN FLTK 1.3.5rc2 RELEASED: Feb 17 2019
Bug fixes and other improvements
- Fix Xcode FLTK project for use under macOS 10.14
CHANGES IN FLTK 1.3.5rc1 RELEASED: Feb 11 2019
New features and enhancements (highlights)
- Add support for macOS 10.13 "High Sierra" and 10.14 "Mojave".
- Add FL/platform.H for compatibility with FLTK 1.4 and higher.
- Improve OpenGL(3+) support.
- Improve Cairo support and (CMake) Cairo detection.
Bug fixes and other improvements
- 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command has been replaced by pkg-config.
- Fix Fl_Tree::insert() with pos out ouf range (issue #18).
- Fix Fl_GIF_Image Color Table handling (STR 3491).
- Make sure not to access Fl_Menu_ widgets if the widget gets
deleted while the menu (pulldown) is open (STR 3503).
- Fix CMake build (fluid) on case sensitive macOS file systems.
- Windows/OpenGL: improve pixel format detection (STR 3119).
- Add 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.
- MacOS platform: fix regression in macOS 10.13 where an unbundled app
had its system menu bar unresponsive.
- MacOS 10.10 platform: Fl_Window::fullscreen() and fullscreen_off()
no longer call Fl_Window::hide() + Fl_Window::show().
The new procedure essentially resizes the window, as done on
the X11+EWMH and Windows platforms. This improves in particular
the possibility to turn an Fl_Gl_Window fullscreen on and off.
- MacOS platform: Support \r\n as end of line used by recent
MS Office apps in clipboard.
- Fix Fl_Text_Editor overstrike mode (STR 3463).
- More consistent and optimized "gleam" scheme box drawing.
- Fix a MinGW build error with new MinGW versions as of Feb 2018
(undefined S_OK and __FD_ISSET), see STR 3454.
- Windows/CMake: Add missing definition of WIN32 for Windows builds.
This seems to be necessary for VS2017 and other compilers that
don't #define WIN32, but FLTK relies on this preprocessor macro.
Autoconf/configure and bundled IDE files #define WIN32 as well.
- Fix illegal memory access after free when closing fluid (valgrind
reports "Invalid read of size 4"), see also STR 3427.
- Fix crash when closing fluid with Fl_Table (STR 3427).
- Fix ignored buffer pre-allocation (requestedSize) in Fl_Text_Buffer.
See fltk.general "Fl_Text_Buffer constructor bug" on Dec 5, 2016.
- Fix Fl_Browser background and text color parsing (STR 3376).
- Fix Windows CreateDC/DeleteDC mismatch (STR 3373).
- Update bundled configure scripts config.guess and config.sub.
- Fix configure --enable-cairo --enable-cairoext,
see report in fltk.general:
https://groups.google.com/forum/#!topic/fltkgeneral/x80qQ6wt0s4
- Fix macOS timer implementation (STR 3387).
- Fix drop-to-FLTK-widget under MSWindows when the desktop is
rescaled (STR 3390).
- Add support for macOS 10.13 "High Sierra". Subwindows don't
move correctly under 10.13 without this fix.
CHANGES IN FLTK 1.3.4-1 RELEASED: Nov 15 2016
Bug fixes and other improvements
- Fix Windows IDE solutions VisualC2008 and VisualC2010 to
build properly if the FLTK source directory is located
in a path that contains spaces.
Note: this is a source tar file update that is only necessary
if you build one of the above mentioned Visual Studio IDE
solutions in a path with spaces. Nothing else changed, no
documentation updates.
CHANGES IN FLTK 1.3.4 RELEASED: Nov 11 2016
Bug fixes and other improvements
- Fix test/native-filechooser help display artifact (STR #3349).
- MacOS: fix a crash when closing a fullscreen window.
- Accept empty Fl_Pixmap in Fl_RGB_Image c'tor (STR #3348).
- MacOS: fix drawing error when a window containing a hidden subwindow
is changed to fullscreen (error visible with the tabs test program).
- MacOS: fix possible crash when enabling fullscreen in test/scroll.
- Add a snapshot of known STR's and RFE's (KNOWN_BUGS.html).
CHANGES IN FLTK 1.3.4rc3 RELEASED: Oct 31 2016
Bug fixes and other improvements
- Fix string truncation in fluid (STR #2722 continued).
- MacOS: fix a small problem where the Command-Quit menu hotkey
may not work if Fl_Native_File_Chooser is used before any
window is shown.
CHANGES IN FLTK 1.3.4rc2 RELEASED: Oct 24 2016
Bug fixes and other improvements
- Make sure the "File Systems" menu item of Fl_File_Chooser
lists "/" as the first mounted file system (Linux/Unix platform).
- Added line numbers to fluid Edit -> Show Source Code viewer.
- Improved fluid's template handling (STR #3335).
CHANGES IN FLTK 1.3.4rc1 RELEASED: Oct 17 2016
New features and extensions
- Added support for Mac OS 10.11 "El Capitan" and 10.12 "Sierra".
- Added full support of true subwindows to the Mac OS X platform.
Window nesting to any depth is possible. An Fl_Gl_Window window or
subwindow can contain Fl_Window's as subwindows.
- Fluid now supports external editors (STR #3213)
See: Edit -> GUI Settings -> Use external editor
- Added method Fl_Widget::is_label_copied().
- Added methods Fl_Copy_Surface::w(), Fl_Copy_Surface::h(),
and Fl_Copy_Surface::draw_decorated_window().
- Added method Fl_Image_Surface::draw_decorated_window().
- Added method Fl_Shared_Image *Fl_Image_Surface::highres_image()
to draw into a high-resolution bitmap image (Mac OS X only).
- Added support for OpenGL version 3 and later.
- Added method Fl_Mac_App_Menu::custom_application_menu_items()
allowing customization of the application menu (Mac OS X only).
- Added 'fluid -u' command-line switch to upgrade fluid files in
batch mode. This option opens a fluid ('.fl') file and saves it
overwriting the old file with the current syntax and library version
number. Use with care (input file is overwritten unconditionally).
- Added FL_ZOOM_GESTURE gesture for OS X (only). Needs implementation
on other platforms.
- Added FL_ABI_VERSION, FL_API_VERSION, Fl::abi_version(), and
Fl::api_version(). Constants can be used to determine the compiled
FLTK version. Functions can be used to find the linked library version.
- Added Fl::abi_check() method to test if the runtime (linked)
ABI version is correct.
- Added Fl_Image::fail() to test if an image was loaded successfully
to allow for easier error detection when loading images (STR #2873).
- Added line numbers to fluid's source code viewer for New -> Code
New configuration options (ABI version)
- FLTK's ABI version can now be configured with 'configure', CMake, or
by editing a supplied file when using the bundled IDE projects.
See documentation in README.abi-version.txt.
1.3.4 ABI FEATURES
- Added deactivated user icon to Fl_Tree.
- Added Fl_Shared_Image::scale(width, height) which gives a shared
image its own drawing size, independently of the size of the
underlying image. This improves image drawing on high resolution
surfaces such as Laser printers, PDF files, and Apple retina displays.
Other improvements
- Configure now correctly sets HAVE_* variables only if both the
library and the header files were found. The configuration process
is aborted if Xft was requested explicitly with --enable-xft and
Xft was not found. The configuration summary now shows _found_
options as opposed to requested options.
- Improved drawing of rounded box (STR #2943).
- Full support of Apple 'retina' displays for which one drawing unit
corresponds to two pixels.
- The Mac OS X platform no longer uses the deprecated AGL
(Apple GL library) to draw OpenGL data. Instead, it uses standard
Cocoa APIs. This allows FLTK to support drawing GL scenes at high
resolution when an Fl_Gl_Window is mapped to a 'retina' display.
- Added Fl_Gl_Window::pixel_w(), Fl_Gl_Window::pixel_h(), and
Fl_Gl_Window::pixels_per_unit() useful for high resolution OpenGL windows.
- fl_read_image() now captures all pixels within the rectangle
described by its arguments, whether they belong to a GL scene
or not (STR #3142). It also captures subwindows of GL windows.
- Fl::delete_widget() now hides the widget or window immediately
(i.e. when called) - only destruction is delayed as before.
- FLTK header files don't expose X11 definitions in user code any more
unless requested by including FL/x.H explicitly or implicitly.
- The PostScript code output when printing images under Linux/Unix
is now much smaller by using lossless compression techniques.
- The Linux/Unix printer dialog now uses BSD-style printing commands
(lpr/lpq) when SystemV-style commands (lp/lpstat) are not available.
- Drawing alpha-blended images under X11 is now accelerated with
Xrender.
- The font used for the FL_COURIER font family was changed on the Mac OS X
platform from 'Courier New' to 'Courier' because it was too thin.
- Text drawing on the Mac platform supports Unicode 'variation selectors'
in the range [0xFE00-0xFE0F].
- Added a Mac OS implementation of Fl_Window::wait_for_expose() that
became necessary with Mac OS 10.10 "Yosemite".
- Added the libfltk target to the Xcode project producing a static
version of the FLTK library (Mac OS X).
- Restored the possibility to call Fl::set_font() before main() starts.
- Allow using the --enable-x11 configure option on the Mac OS platform
which produces an X11 version of the FLTK library (don't use unless
you know what you're doing).
- FLTK code and fluid-generated code can be used in static initializers.
- Added light gray separator line to fluid's widget browser (STR #2997).
- Improved tooltip behavior for huge tooltips: remove flicker, support
key/mouse dismiss (STR #2650).
- Modifier key names displayed in shortcut labels can now be localized.
See documentation of fl_shortcut_label(). You can set modifier key
names for Ctrl, Alt, Shift, and Meta by assigning global string
pointers to your translated modifier key names.
- Many documentation improvements and fixes.
- Fixed many compiler warnings (STR #2988).
- Fluid now generates code with less compiler warnings (STR #2813).
- Many CMake improvements and fixes. Note: CMake is mostly operating
now, but not yet recommended for production use. Please test and
report issues.
- Updated bundled zlib from 1.2.5 to 1.2.8.
- Updated bundled libjpeg from jpeg-8c to jpeg-9a.
Bug fixes
- Fix potential crash when using keyboard navigation on Fl_Tabs
widget without children (STR #3333).
- Fix potential crash if Fl_Window::icon(NULL) was called to clear
(reset) a window icon. This is now legal and documented behavior.
The same applies to Fl_Window::default_icon().
- Allow widget callback to be NULL, i.e. no callback (STR #2835).
- Fixed Fl_Help_View buffer overflow (STR #3275).
- Fl_Browser now correctly adjusts its scrollbars when the default
text size is changed with textsize(int) (STR #3057).
- Fixed Fl_Text_Display/Fl_Text_Editor slow scrolling, line number
display, wrap mode "hiding" text behind scrollbars, and more
scrollbar handling (alignment) (STR #3272).
- Fixed valgrind warning (uninitialized variable) in Fl_Window.
Visible only with FLTK_ABI_VERSION >= 10303, since FLTK 1.3.3.
- Fixed Windows drag'n'drop not showing insert position if the drop
target is inside the same window or process (STR #3209).
- Fixed undefined reference building shared cairo library (STR #3276).
- Fixed Fl_Browser if text argument to some methods is NULL (STR #3269).
- Fixed missing image release in fluid (STR #2840).
- Fixed out-of-bounds memory access in fluid (STR #3263).
- Fixed trailing white space in fluid .fl files (STR #3239).
- Several box types were not drawn correctly when deactivated.
The background color for deactivated widgets is now correct:
fl_inactive(color()) (STR #2907).
- Fix inconsistent interpretation of ld() in image handling
(STR #3308). This is a minor issue since ld() is usually 0 or
w()*d(). Documentation has been fixed, and ld() handling is now
consistent in Fl_(RGB_)Image and fl_draw_image() and friends. See
documentation of Fl_Image and Fl_RGB_Image for more information.
- Fixed Fl_Pixmap (background) drawing to respect the clip region
(STR #3206).
- Fixed reading .pbm image files: 1 is now interpreted as black,
and images whose width are a multiple of 8 are correctly read.
Note: if you relied on the faulty behavior you may need to fix
your image files.
- Restored window background drawing, particularly the 'plastic'
scheme's background (STR #3059). This was a regression since
FLTK 1.3.0.
- Prevent sending (FL_SHORTCUT) events to inactive widgets (STR #3216).
- Fixed button label clipping (STR #3237).
- Fixed Fl_Menu_::item_pathname() handling of descending submenu
pointers (STR #3177).
- Fl_Text_Display: style buffer colors are no longer manipulated by
fl_contrast() for normal text drawing (fltk.coredev thread started
04/08/15, Subject: "RFC: Fl_Text_Display style buffer color weirdness")
- Fl_Tree::deactivate() now affects draw color of items (must have
ABI 1.3.3 or higher enabled). For icons to draw deactivated,
enable ABI 1.3.4. (test/tree has a 'deactivate tree' button)
- Fl_Tree::find_item() did not find items if the pathname contained
identical strings (STR #3234).
- Fixed possible bad border effect when a set of radio menu items
is located first in its menu (STR #3176): Fl_Menu_Item::set_only()
is deprecated and replaced by Fl_Menu_::set_only(Fl_Menu_item*).
- Restore the correct state of mouse buttons and keyboard modifier keys
after closing a file or printer dialog (STR #3221).
- Fix for deactivate colors issue with Fl_Text_Display/Editor (STR #3219).
- Fixed issue with MSWindows platform where the program kept running
after closing all its windows (STR #3165).
- Fix potential buffer overflow (MSWindows: BEX64 error) and problem with
MSWindows environment variables "HOME"(MinGW) vs. "UserProfile"(DOS)
- Fix issue with MSWindows platform where a window would decrease
in size after each close/open (STR #3167).
- Fix undefined reference XGetUtf8FontAndGlyph (STR #3191).
- Fix potential keyboard hangup (STR #3192).
- Fix for: .xbm images were not previewed (STR #3131).
- Fixed crash on Mac platform when resizing a not yet shown() Fl_Gl_Window.
- Fixed potential Windows GDI leak (STR #3254).
- Fixed Linux/Unix potential program hang when dialog pops up while
a menu is open (STR #3179).
- Fixed a crash when a Unix/Linux program calls take_focus() before any
window has been show()n.
- Fixed an error on the Mac platform when drawing to an Fl_Image_Surface
object without using the Fl_Image_Surface::draw() method.
- Fixed STR #3268 where a fullscreen window could become relocated
behind the menu bar and dock (Mac OS only).
- Fixed STR #3207: ^C not working when numlock or capslock is on.
- Fixed code editor in Fluid (STR #3184).
- Fixed a potential hangup of the Fl::awake() queue under Windows if
a window is resized or moved while the Fl::awake() message is sent
(STR #3143).
- Fixed a regression: restore the possibility to call
fl_draw_image(buf,X,Y,W,H,D,L) with negative D and/or L arguments.
- Fixed overflow in Fl_Valuator::precision(int) to 0...9 (STR #3280).

see Fl_Window::icon() for more info.
- New method to set any custom cursor, based on a Fl_RGB_Image object.
Also changed fallback cursors to use this method, so that fallback
cursors are handled in a platform independent manner (STR #2660).
- New ability to convert Fl_Pixmap to Fl_RGB_Image (STR #2659).
- Support for full screen windows over multiple monitors.
- New optional line numbers in Fl_Text_Display and options to control

- New support for the Mac OS text input system that deals with character
composition and input of languages with large character sets (e.g.
Chinese and Japanese). This implementation has been reported to work
well for Chinese. Superficial testing suggests it's also operational
for Japanese. In-depth testing remains needed though.
Other improvements

may want them (STR #3104).
- Check compiler support of -fvisibility, -fvisibility-inlines-hidden,
and use it, if available. Reduces shared library size.
- Drag'n'drop behaves better now: if text is dropped in the widget it
comes from, then it works like cut and paste.

Enter key now selects the file again.
- Fixed a bug in Fl_Native_File_Chooser (Windows) for some file name
input filters (STR #3101).
- Fixed out-of-bounds memory access in Fl_Text_Display (STR #2730).
1.3.3 ABI FEATURES
To enable the following ABI features, put:
#define FLTK_ABI_VERSION 10303
..at the top of your FL/Enumerations.H and rebuild FLTK and your app.
- Added Fl_Window::shape(const Fl_Image*) to create arbitrarily-shaped
windows
- Made Fl_Help_View::handle() public and Fl_Help_View::draw() protected
to enable inheritance and for consistency (STR #2834).
Note: both methods were private.
- Made Fl_Scroll::recalc_scrollbars() protected so that it can be used
in derived widgets to calculate scrollbar visibility and positions.
- Added Fl_Table::tab_cell_nav() for controlling Tab key navigation of table
- Added Fl_Tree::get_selected_items(), returns the selected items as an array
- Added Fl_Tree::item_draw_callback(), letting one define a custom draw
function for Fl_Tree_Item's.
- Fl_Tree: various related changes:
o Added horizontal scrollbar
o Separated draw() and tree size calculation
o Added new public methods:
> resize() -- uses optimized dim calc, avoids tree recalc
> next_item() -- added parameters: direction, visibility
> extend_selection() -- added parameters, improved algorithm
> calc_dimensions() -- calc tix/y/w/h, tox/y/w/h and scrollbars
> calc_tree() -- calc tree_w/tree_h
> recalc_tree() -- schedules calc_tree()
> first_visible_item(), last_visible_item(), next_visible_item()
> first_selected_item(), last_selected_item(), next_selected_item()
o Added protected variables:
> _tix/y/w/h -- tree widget 'inner' dimension
> _tox/y/w/h -- tree widget 'outer' dimension
> _tree_w,_tree_h -- entire tree hierarchy width/height
o Deprecated:
> item_clicked() -- use callback_item() instead
> first_visible() -- use first_visible_item() instead
> last_visible() -- use last_visible_item() instead
- Fl_Tree_Item: various related changes:
o Added Fl_Tree ptr: needed for auto-recalc when item modified directly
o Added new methods tree(), recalc_tree()
o Added new ctor that accepts Fl_Tree*
o draw() parameters changed to include tree size calculations
o Deprecated:
> ctor using Fl_Tree_Prefs parameter (Fl_Tree* version better,
and must be used for 1.3.3 ABI features to work correctly)
> next_displayed() -- use next_visible() instead
> prev_displayed() -- use prev_visible() instead
- test/tree: added tests for newly added features

Fl_Widget.
- Added new label and image alignments (STR #2269)

deletion in callbacks. This is used in Fl_Widget::do_callback()
to prevent accessing widgets after deletion in the callback.

title (STR #2562).
IDE Support and Command Line Build Options
- FLTK now supports Apple Xcode 3, MS VisualC 2008, and
MS VisualC 2010. MS VisualC 6 support is maintained as a
compatibility base for VisualC.net, etc. . FLTK continues
to support configure/make and improved CMake build files.
- Added step by step README's for MSWindows, OS X, and four
Linux distros.
- Added "ide" subdirectory for all IDE support files
- Added template to generate new projects with Xcode.
- Added --enable-cairo and --enable-cairoext configure options.
- redesigned CMake files (STR #2317).
- The new configure option --enable-x11 (lowercase 'x') enables
Cygwin builds under Windows (with --enable-cygwin) to use X11
instead of GDI drawing (STR #2147, #2183) and is ignored otherwise.
- Changed "fltk-config --post foo" to create an application
bundle rather than attaching a resource fork.
- Changed default for configure option --with-links for common
misspellings on case sensitive file systems like Unix/Linux.
The new default is --without-links; use --with-links on
Unix/Linux only if you need the links (e.g. lowercase '.h')
