The central display of the cube is a separate subclass of Fl_Gl_Window called CubeView. The window is of class CubeViewUI, and is completely generated by FLUID, including class member functions. Widgets may either call a named callback function that you write in another source file, or you can supply a small piece of C++ source and FLUID will write a private callback function into the. An unnamed widget has a blank name and no pointer is stored. This can be used to get the widgets into structures. In this case FLUID assigns a pointer to the widget to the name, but does not attempt to declare it. A complex named object has punctuation such as '.' or '->' or any other symbols in its name. In this case FLUID defines a global variable or class member that will point at the widget after the function defining it is called. A named widget has a legal C++ variable identifier as its name (i.e. Widgets created by FLUID are either 'named', 'complex named' or 'unnamed'. Each function defines one or more FLTK windows, and all the widgets that go inside those windows. Normally the FLUID file defines one or more functions or classes which output C++ code. cxx file so it still appears to be a single source file. Most programs are more complex than this, so you write other.

cxx file a single source file to compile. FLUID also supports localization ( Internationalization) of label strings using message files and the GNU gettext or POSIX catgets interfaces.ДЄ simple program can be made by putting all your code (including a main() function) into the.

cxx file defines all the objects from the. These files are text, and you can (with care) edit them in a text editor, perhaps to get some special effects.ДЇLUID can 'compile' the. The Fast Light User Interface Designer, or FLUID, is a graphical editor that is used to produce FLTK source code.
