Free fltk software for linux

FLTK project includes all of the usual widgets to develop your applications, and new widgets can be created easily through C++ subclassing. All widgets support keyboard shortcuts and can be controlled both via the keyboard or mouse.
The Fl_Button class supports push, check (Fl_Check_Button), round (Fl_Round_Button), and "light" (Fl_Light_Button) button styles; all styles can operate in momentary (press and release), toggle (press on, press off), or radio (press one of many) modes, so it is possible to create almost any kind of button from a single widget.
The Fl_Input_, Fl_Text_Display, and Fl_Help_View widgets provide simple to complex text input and output facilities. The Fl_Text_Display widget is based on a C++ version of the NEdit softwares extensible text editor API.
The Fl_Valuator class provides a variety of numeric input controls including scrollbars (Fl_Scrollbar) and sliders (Fl_Slider).
The Fl_Menu_ class provides several menu-based controls including menubars (Fl_Menu_Bar) and combo boxes (Fl_Choice).
The Fl_Browser_ class is the basis for list controls. The Fl_Browser widget shown at right lists lines of plain text. Other widgets list files, widgets, and so forth.
User interfaces can be organized using scroll areas (Fl_Scroll), tabs (Fl_Tabs), tiles (Fl_Tile), and wizards (Fl_Wizard).
FLTK also provides standard dialogs for alerts, button choosers, color choosers, file choosers, help browsers, messages, passwords, and text input.
Finally, FLTK 1.1.x offers two appearance schemes: "standard" and "plastic". FLTK 2.0 will extend this to include platform schemes as well as user-defined schemes. Colors and fonts automatically adjust to the current user preferences.
Enhancements:
- This release fixes many bugs, adds some new example programs, and adds many new improvements to the FLUID software, including multi-level undo, syntax highlighting in all code fields, widget alignment and sizing guides, dialog templates, widget subclasses, and printing and testing of user interfaces within FLUID.

gtk-FLTK project provides helper functions to use FLTK together with GTK.

Were using SWIG to create the Python wrapper. Perl support has been discontinued for the time being.
TCL, Guile, and Java support should not be that hard to add (this is left as an exercise for the reader).
There are two packages in this project: pyFLTK and pyFLTK2. They wrap FLTK (version 1.1) and FLTK2, respectively. While FLTK and with it pyFLTK is quite stable, FLTK2 is still a moving target and rather instable. The package pyFLTK2 is therefore a proof of concept, rather than a fully working Python extension.
A utility named flconvert is also provided that allows for the conversion of fluid files to Python code. fluid is an interactve GUI builder for the FLTK toolkit and comes with the distribution of FLTK.
Main features:
- Cross platform GUI toolkit (Windows, Linux, Unix, Mac, ...)
- Easily deployable using py2exe.
- Small footprint as compared to other toolkits.
Enhancements:
- Fixed memory leak in Fl_Preferences result strings.
- Added V3.12 of Fl_Table, courtesy of Gregg Ercolano. Note: the syntax of find_cell has changed, the parameters X, Y, W, H are now output only (used to be in/out).
- Added some documentation, see docs/preface.html!
- Added test/editor.py and test/simple_table.py.
- Implemented Fl_Text_Display.highlight_data.
- Fixed bug in Fl_Text_Buffer.remove_modify_callback()
- Added possibility to register multiple modify callbacks with Fl_text_Buffer.
- Fixed missing output parameter for Fl_Text_Buffer: findchar_forward, findchar_backward, search_forward, search_backward, etc
- Fixed compilation issue for MinGW (wrongly linked with msvcrt instead of mscvr71).
- Fixed compilation issue for g++ 4.1.1 (ListSelect).
- Added typemap to convert Fl_Button.value() from char to int.
- Added funtion mt_run.
- Added wrappings for Fl.repeat_timeout and Fl.remove_timeout.
- Fixed bug in OpenGL part of compilation.
- Fixed Cygwin compilation issue by adding -DNOMINMAX.
- Redesigned memory management. Removed postprocessing step and added all memory management to interface files. Ownership of objects should now be properly transferred between fltk and Python.
- Added interface files to distribution.
- Added auto configuration to setup.py. Missing OpenGL and Forms libraries should be recognized now.
- Added command line switches --disable-gl and --disable-forms to setup.py
- Added stubs for missing OpenGL and Forms libraries.
- Added compilation support for Sun Solaris.

This program is very simple for burning iso images created by mkisofs or any other foftware. It use burncd as write program.
This is initial release and it can write only data images in single or multisession mode.
Main features:
- Quick erase for CD-RW disks
- Full erase for CD-RW disks
- DAO writing mode
- Multi device support in one moment
- Very simple and fast(using FLTK 1.1.6 library)

Otk is a portable widget library for making graphical user interfaces (GUIs) for application programs. Otk project emphasizes simplicity without eliminating capability. Open graphics Tool Kit supports neutrally: Linux, Unix, Microsoft Windows, and Mac OSX. It is based on OpenGL, and C. Otk provides the following basic widgets:
- Panel - The "container" widget.
- Text Label - Text labels.
- Button - Buttons with labels and call-backs to user functions.
- Text Form Box - Accept text with function call-back. Also scrollable editor window.
- Pull-down Menu - Display hierarchical menu-lists with user function call-backs on mouse release.
- Slider Control - Slider control with call-back.
- Sub-windows - Detachable self-managed windows.
- Many other widgets ...
- Gadgets - High level widgets.
Although initially intended for use with C programs, Otk can be accessed from, or extended to, other languages. Otk addresses several issues with previous graphics toolkits, such as X-Windows, X-Motif, MFC, Tcl/TK, Gtk, Awt, Swing, Glow, FLTK, etc..
Otk deviates from previous graphics environments in several important ways.
- Based on OpenGL - Well supported on most platforms. Clients tend to have the right support files. Easily builds on all platforms. Uses graphics card acceleration when available. Common look and feel. Contains internal default font with arbitrary scale, boldness and slant. Additional fonts can be added.
- API designed from application programmers viewpoint - Simplified interface. Sensible defaults. Most common functions require one line. But flexibility is not limited because defaults can be modified.
- Minimal library files - Link to-, or include-, one file.
- Direct window-size % relative layout - Specify positions and sizes as percentage of container window. Resizing is automatic and proportional. Traditional pixel-coordinate or framework modes can also be supported.
- Colors can be expressed directly as r,g,b values. (No indirect color index tables.)
Enhancements:
- Paste from the clipboard was added.
- A fix was mde to disk-draw for elliptical disks and the control-key handler.
- The slider knob was widened.
- A new indicator-light gadget was started.
- Several updates were made to support Otk-GuiBuilder.

fldiff is a graphical diff program that shows the differences between two files/directories, or a file/directory and a CVS or Subversion repository. fldiff project is inspired by xdiff (Motif-based) and xxdiff (Qt-based), whose choice of GUI toolkit has hampered their portability to many of the systems I work with.

fldiff uses the Fast Light Toolkit (FLTK) and has been tested on AIX, IRIX, Linux, MacOS X, and Solaris, and should also run on Windows.

My File Manager is a small and lightweight file manager. It was developed to provide a small and fast file manager, which has only a few dependencies from other packages, but including some interestings things like mount partitions, minimalistic burning capability and mass renaming files. MFM use FLTK graphics toolkit.

- Selectable shown fields (permissions, users, groups, date and size)
- Various sort options
- Rename group of files
- Change attributes of group of files
- Compress files
- Burn CD/DVD
