FLTK Ada Binding

- -

Git repository: Link
-Estimated status: 80% complete

A few noteworthy bugfixes have been applied to the binding.

- -

First, unbeknownst to me the Fl_Widget constructor doesn't copy the given label string inside -FLTK and merely stores a pointer. This meant that declaring several Widgets in a row each with their -own different label could have unexpected and erratic results. Easily fixed by ensuring the binding -constructor also calls copy_label() afterwards.

- -

And second, somehow I had made an oversight with the type assigned to Color, using a signed -Integer when it really needed an unsigned modular type with 32 bits of range. Again, easily fixed -but even more annoying since it was my fault to begin with.

- -

I'm sure the other guy aside from me who takes an interest in this binding will be happy about -these. You know who you are.

This binding is now complete enough for most purposes. It certainly took more effort than -expected, in part due to underestimation of how much needed binding. The vast majority of useful -classes are now usable in Ada, with a few exceptions such as the Fl_Browser, Fl_Help_View, Fl_Table, -and Fl_Tree widgets.

- -

Noteworthy features and modifications include:

- - -

A mapping of what C++ headers and methods correspond to what Ada packages, functions, and -procedures is included. Also, the below "Hello world" code sample has been modified to work with the -updated binding.

FLTK, or by its full name the Fast Light Toolkit -, is a graphical widget toolkit noteworthy for being so lightweight that it is commonly -statically linked. Projects that make use of it include the Dillo web browser, the -FLWM X window manager, and the -Equinox Desktop Environment. There are bindings for it in several languages, including Python, -Perl and Ruby, but not Ada. Until now!

- -

This is a spinoff from Adapad, and so despite not yet being complete it can be at least -guaranteed to be enough to write a text editor. It's a thick, loosely coupled binding, accomplished -by first exporting the interface to C, then importing that to Ada. Attempted usage of the internal C -interface as a binding on its own is not supported.

- -

A typical FLTK Hello World program in Ada:

-
- -with - FLTK.Widgets.Groups.Windows, - FLTK.Widgets.Boxes; - -function Hello_World return Integer is - - My_Win : FLTK.Widgets.Groups.Windows.Window := - FLTK.Widgets.Groups.Windows.Forge.Create (100, 100, 200, 200, "Untitled"); - - My_Box : FLTK.Widgets.Boxes.Box := - FLTK.Widgets.Boxes.Forge.Create (50, 50, 100, 100, "Hello, World!"); - -begin - - My_Win.Add (My_Box); - My_Win.Show; - - return FLTK.Run; - -end Hello_World; - -
- -

Aside from reworking the types to better fit the strongly typed philosophy of Ada, the entire -library has been structured to avoid explicit heap usage. As you can see from the above example, the -intended use is to declare FLTK objects on the stack. Allocation and deallocation of the C++ -internals is handled automatically.

- -

A few other minor changes were involved, such as requiring widgets to be explicitly added to a -group rather than implicitly being added to the last group not yet ended. At the moment the package -specifications should provide sufficient information to allow programmers to work with the library. -
