This may seem relly naive but I'm only new to C++. If, in the future I want to build charting software for stock-charts, etc and want a very professional and portable widget toolkit to use with C++ which one should I use and what should I be looking for.
Are some better than others? Are they free or do you pay for them?
Obviously I'm not so familiar with this area so lots of detail woudl be great. If anyone knows some good books that can answer allot of these questions that would also be very helpful.
Thanks so much.
