<H2>History of FLTK</H2>
|

It has always been Bill's belief that the GUI API of all modern

systems is much too high level. Toolkits (even FL) are <I>not</I> what
|
||||
should be provided and documented as part of an operating system. The

<P>It has always been Bill's belief that the GUI API of all modern
|
||||
systems is much too high level. Toolkits (even FL) are <I>not</I> what
|
||||
should be provided and documented as part of an operating system. The
|
||||
system only has to provide arbitrary shaped but featureless windows, a
|
||||
powerful set of graphics drawing calls, and a simple <I>unalterable</I>
|
||||
method of delivering events to the owners of the windows. NeXT (if
|
||||
method of delivering events to the owners of the windows. NeXT (if
|
||||
you ignored NextStep) provided this, but they chose to hide it and
|
||||
tried to push their own baroque toolkit instead...
|
||||
<P>Many of the ideas in FLTK were developed on a NeXT (but <I>not</I>
|
||||
using NextStep) in 1987 in a C toolkit Bill called "views". Here he
|
||||
came up with passing events downward in the tree and having the handle
|
||||
routine return a value indicating the used the event, and the
|
||||
table-driven menus. In general he was trying to prove that complex UI
|
||||
ideas could be entirely implemented in a user space toolkit, with no
|
||||
knowledge or support by the system. </P>
|
||||
<P>After going to film school for a few years, Bill worked at Sun
|
||||
Microsystems on the (doomed) NeWS project. Here he found an even
|
||||
better and cleaner windowing system, and he reimplemented "views" atop
|
||||
that. NeWS did have an unnecessarily complex method of delivering
|
||||
events which hurt it. But the designers did admit that perhaps the
|
||||
user could write just as good of a button as they could, and officially
|
||||
exposed the lower level interface. </P>
|
||||
<P>With the death of NeWS Bill realized that he would have to live with
|
||||
X. The biggest problem with X is the "window manager", which means
|
||||
that the toolkit can no longer control the window borders or drag the
|
||||
window around. </P>
|
||||
<P>At Digital Domain Bill discovered another toolkit, "Forms". Forms
|
||||
was similar to his work, but provided many more widgets, since it was
|
||||
used in many real applications, rather then as theoretical work. He
|
||||
decided to use Forms, except he integrated his table-driven menus into
|
||||
it. Several very large programs were created using this version of
|
||||
Forms. </P>
|
||||
<P>The need to switch to OpenGL and GLX, portability, and a desire to
|
||||
use C++ subclassing required a rewrite of Forms. This produced the
|
||||
first version of FLTK. The conversion to C++ required so many changes
|
||||
it made it impossible to recompile any Forms objects. Since it was
|
||||
incompatible anyway, Bill decided to incorporate his older ideas as
|
||||
much as possible by simplifying the lower level interface and the event
|
||||
passing mechanisim. </P>
|
||||
<P>Bill received permission to release it for free on the Internet,
|
||||
with the GNU general public license. Response from Internet users
|
||||
indicated that the Linux market dwarfed the SGI and high-speed GL
|
||||
market, so he rewrote it to use X for all drawing, greatly speeding it
|
||||
up on these machines. That is the version you have now. </P>
|
||||
<P>Digital Domain has since withdrawn support for FLTK. While Bill is
|
||||
no longer able to actively develop it, he still contributes to FLTK in
|
||||
his free time and is a part of the FLTK development team. </P>

<H2>Features</H2>
|
||||
FLTK was designed to be statically linked. This was done by splitting
|
||||
it into many small objects and desigining it so that functions that are
|
||||
not used do not have pointers to them in the parts that are used, and
|
||||
thus do not get linked in. This allows you to make an easy-to-install
|
||||
program, or to modify FLTK to the exact requirements of your
|
||||
application, without worrying about bloat. FLTK works fine as a shared
|
||||
library, though, and has started being included on Linux distributions.

<H2>What Does "FLTK" Mean?</H2>
|
||||
FLTK was originally designed to be compatible with the Forms Library
|
||||
written for SGI machines. In that library all the functions and
|
||||
structures started with "fl_". This naming was extended to all new
|
||||
methods and widgets in the C++ library, and this prefix was taken as
|
||||
the name of the library. It is almost impossible to search for "FL" on
|
||||
the Internet, due to the fact that it is also the abbreviation for
|
||||
Florida. After much debating and searching for a new name for the
|
||||
toolkit, which was already in use by several people, Bill came up with
|
||||
"FLTK", and even a bogus excuse that it stands for "The Fast Light Tool
|
||||
Kit".

<H2>Building and Installing FLTK Under UNIX</H2>
|

In most cases you can just type "make". This will run configure with
|
||||
the default of no options and then compile everything.
|
||||
<P>FLTK uses GNU autoconf to configure itself for your UNIX platform.
|
||||
The main things that the configure script will look for are the X11 and
|
||||
OpenGL (or Mesa) header and library files. If these cannot be
|
||||
found in the standard include/library locations you'll need to define the
|
||||
<tt>CFLAGS</tt>, <tt>CXXFLAGS</tt>, and <tt>LDFLAGS</tt> environment
|
||||
variables. For the Bourne and Korn shells you'd use:</P>

By default configure will look for a C++ compiler named <tt>CC</tt>, <tt>c++</tt>,

<H2>Building FLTK Under Microsoft Windows</H2>
|

There are two ways to build FLTK under Microsoft Windows. The first
|
||||
is to use the Visual C++ 5.0 project files under the "visualc"
|
||||
directory. Just open (or double-click on) the "fltk.dsw" file to get
|
||||
the whole shebang.
|
||||
<P>The second method is to use a GNU-based development tool with the
|
||||
files in the "makefiles" directory. To build using one of these tools
|
||||
simply copy the appropriate makeinclude and config files to the main
|
||||
directory and do a make: </P>
