Looking again at the program I've got the sizeof numbers I did a mistake
because it printed more numbers together:
Flu_Tree_Browser = 524
Flu_Tree_Browser::Node = 92
I was thinking of only have the minimun on an Fl_Tree_item and derived
ones to each specific task.
Lets say:
class Fl_Tree_Item {
char _open; // item is open?
char _visible; // item is visible?
char _active; // item activated?
char _selected; // item selected?
Fl_Tree_Item_Array _children; // array of child items
Fl_Tree_Item *_parent; // parent item (=0 if root)
#if FLTK_ABI_VERSION >= 10302
Fl_Tree_Item *_prev_sibling; // previous sibling (same level)
Fl_Tree_Item *_next_sibling; // next sibling (same level)
#endif /*FLTK_ABI_VERSION*/
}
class Fl_Tree_Item_szString : public Fl_Tree_Item {
char *label;
//using the same stype as Fl_Tree
}
class Fl_Tree_Item_Label : public Fl_Tree_Item {
Fl_Label *label;
}
class Fl_Tree_Item_Widget : public Fl_Tree_Item {
Fl_Widget *widget;
}
class Fl_Tree_Item_...
----output that made me get wrong numbers-----
Flu_Tree_Browser 524 : Flu_Tree_Browser::Node 92
sizeof(Flu_Tree_Browser::Node): 92
