vfltk

V wrapper for FLTK.

As FLTK is written in C++; V must utilize a C wrapper for ease. The work cfltk is one such wrapper, which can be found here

To use vfltk; you must build from the above project:

libcfltk.a, libfltk.a [Required]
libfltk_forms.a, libfltk_gl.a, libfltk_images.a [Optional, depending on how you use FLTK]

Author Instructions on building cfltk

$ git clone https://github.com/moalyousef/cfltk
$ cd cfltk
$ git submodule update --init --recursive
$ cmake -B bin -S .
$ cd bin
$ make

After building:

libcfltk.a can be found in cfltk/bin --> associated headers in cfltk/include
libfltk.a, libfltk_forms.a, libfltk_gl.a, libfltk_images.a are in cfltk/bin/fltk/lib

FLTK in V

To use FLTK in V, at minimum you will need these libraries:

pthread
X11
Xext
Xinerama
Xcursor
Xrender
Xfixes
Xft
fontconfig

Optional image support:

png16
jpeg

Optional text internationalization:

pango-1.0
pangoxft-1.0
gobject-2.0
cairo
pangocairo-1.0

You should be able to scoop most the essentionals up with

$ sudo apt-get install libx11-dev libxext-dev libxft-dev libxinerama-dev libxcursor-dev libxrender-dev libxfixes-dev libpango1.0-dev libgl1-mesa-dev libglu1-mesa-dev

Current state

At present, this is just an example with Window widget, Button widget, and a callback.

In due time a wrapper module will be implemented.

Required C-to-V Flags

#flag -I/path/to/cfltk/includes
#flag -L/path/to/cfltk.a/lib
#flag -lcfltk -lfltk -lfltk_images
#flag -ldl -lm -lXext -lXft -lfontconfig -lXrender -lpthread -lX11 -lXinerama -lXfixes -lXcursor

Notice you must also link against dl (dynamic loader) and m (math library).

Unless you're using images, you don't need to link against fltk_images; but it's shown for completeness.
