This is wrong, you must create widgets dynamically when inserting them
to a window. This might work better:
Fl_Output* pO_Test= new Fl_Output(50, 50, 300, 500, "Test");
It is not necessary to keep pO_Test, because the window grabbed the
Fl_Output, but you can use it for more initialisation, e.g. setting
pO_Test->callback(), or something like that.
