Jun 16, 2011: FLTK 1.3.0 final version released! Michael Sweet Jul 10, 2011 top right image
The FLTK developer team is proud to announce the release of FLTK 1.3.0 .

FLTK is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation. FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

FLTK 1.3.0 has been a huge step in the successful FLTK 1 series. All strings in FLTK are now handled in UTF-8 format and support the full range of Unicode character sets everywhere. International Input Methods are supported on all platforms. Two great new widgets were added, Fl_Tree and Fl_Table. Printing is now as easy as drawing into a window, and supports window printing of FLTK GUIs including OpenGL. 

Internally, FLTK has been upgrade to run on current Unices, MS Windows 7, and OS X via Cocoa. All graphics calls now use device abstraction.

FLTK is provided under the terms of the GNU Library Public License, Version 2 with exceptions that allow for static linking.

This is the final FLTK 1.3.0 release. Enjoy!


New Features

- Added full UTF-8 Unicode support throughout FLTK and Fluid
- Added Fl_Tree widget for hierarchical views
- Added Fl_Table widget for widget layout
- Added Fl_Native_Filechooser as a widget and global options
- Added printing support (Fl_Printer class and friends) for native printing on Windows and Mac OS X, PostScript printing on X11 with CUPS or lp, and PostScript file output on all platforms
- Added Fl_Device abstraction layer for all drawing functions
- Moved OS X code base to the current Cocoa toolkit thanks to the awesome work of Manolo Gouy (STR #2221)

API and ABI compatibility to FLTK 1.1.x

- All strings are expected to be in UTF-8 Unicode encoding
- Replaced Fl_Scroll::position(int,int) with scroll_to(int,int) to avoid overriding Fl_Widget::position(int,int) (STR #1303)
- Although FLTK 1.3 maintains source code compatibility as good as possible, the binary interface changed considerably.
- Updated the bundled libpng to v1.2.40 (released Sep. 10, 2009)
- Update lib png access (STR #2442)

API enhancements and changes

- Changed font index to 32 bit to allow more than 256 fonts
- Changed font height to 32 bit to allow fonts taller than 256 pixels
- Changed widget coordinates to 32 bit
- Corrected const methods of Fl_Text_{Buffer|Display|Selection} to be declared const, corrected an Fl_Text_Buffer attrib. typo
- All draw() methods of widgets are now protected (STR #2142).
- Changed Fl_Group::clip_children() to public (STR #2017)

- Changed hide() and show() methods. They are now virtual from Fl_Widget.
- Added new label and image alignments (STR #2269)
- Added global UI options (STR #2471)

- Added Fl::screen_dpi API

IDE support and command line build options

- FLTK now support Apple Xcode 3, Xcode 4, 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.


- Added argument-less constructor in Fluid Widget Class
- Added jpeg support to Fluid image() element
