Re: Consider using std::vector (C++98 / C++11) Bill Spitzak 11:38 Jul 15 top right image
 
Back when fltk was created using std:: stuff was certainly much worse performance and storage wise compared to directly writing pointer manipulation like in C. However that has certainly changed over time, modern implementations especially on Linux are highly optimized. I suspect using std::vector<FlWidget*> everywhere possible would not cause any problems or incompatibility, the old widgets did hide the implementation pretty well.

Isn't it time to think about using simple std::container types in FLTK?

I've seen the necessity of using vectors in some situations (patches),
particularly useful would be

- std::vector<int>
- std::vector<Fl_Widget *>

I'm not asking to rewrite existing code, just to add such containers
where useful. The potential new widget Fl_Flex
(https://github.com/osen/FL_Flex) would be an example but I know of at
least one patch that suggested using a vector.

I don't know about real compatibility issues with old (maybe embedded)
systems and such. Do we still need to take care or can we "move our code
base a little forward" WRT more modern C++ standards? According to
https://www.cplusplus.com/reference/vector/vector/ class vector is
defined in C++98 with some additions in C++11.

If not (and I think one valid reason is enough, like a veto), then I
suggest to add some similar classes for internal usage rather than
inventing the wheel over and over again. I could search and give some
examples but I don't want to do this now.

All comments would be appreciated, not only from FLTK devs. Thanks.
