FLTK is a C++ graphical user interface tookit for X(Unix), OpenGL and
Microsoft Windows(Nt 4.0, 95, 98).
We won't cover much about FLTK in here because code examples are included
in the skeleton code. But it is good to learn the basics of FLTK
so that you can improve your UI later on if you choose to do so. You can
click
#include <FL/Fl.h>
#include <FL/Fl_Window.H>
#include <FL/Fl_Box.h>
int main(int argc, char *argv) {
FL_Window *window = new Fl_Window(300, 180);
FL_Box *box = new Fl_Box(20, 40, 260, 100, "Hello World!");
box->(FL_UP_BOX);
box->labelsize(36);
box->labelfont(FL_BOLD);
box->labeltype(FL_SHADOW_LABEL);
window->end();
window->show(argc, argv);
return Fl::run()
}
The statement "FL_Window *window = ..." will create a window with the
specified size(36). The next statement will create a box with the "Hello
World!" string in it. To format the box and string, we can use
"labelfont", "labeltype", etc.
