FXDataTarget can be used to connect a widget to an application variable without any of the
tradional "glue" programming code.

The widgets below are connected (via FXDataTarget) to an integer, real, string, option, and
color variable, respectively.

Changing one of them will cause all widgets connected to the same FXDataTarget to
update so as to reflect the value of the application variable.

The progress bar below shows a time-varying variable, demonstrating that widgets
can be updated via FXDataTarget's regardless how the variables are changed.

Note that the "Option" pulldown menu is also connected to the option variable!
