Hi Pierre,

Hi Manolo, thanks for the answer.

One key information is that the destructor of an Fl_Group also deletes all the group's children :
see https://www.fltk.org/doc-1.3/classFl__Group.html#a9a71aac1ca586825ff0c790f8f99f9cf

Now, because FLTK widgets are placed in Fl_Window's and Fl_Window's are Fl_Group's,
when a window is deleted, all the widgets it contains are deleted too.

Ok, but if you have code that creates a pointer to a FL_button with new, like the following, don't you have to register that FL_Button somewhere so that it is know as a member? Is the new operator overridden by FLTK?

Fl_Button *fluidButton = new Fl_Button(25, 80, 70, 50, "button2");

/Pierre
