[fltk.general] Re: Run code when Fl_Scroll stops scrolling? - Forums

I wanted something similar a few weeks ago (posted it with the title "Problem with redraw() / draw()"). The solution offered to me by some generous fltk fan (I don't remember huis name) was to provide a new callback function for the existing scrollbars in Fl_Scroll and intercept the yposition from there. Very neat! I attach the code with solution.

Hello!

As described in https://stackoverflow.com/questions/73653471/fltks-fl-scroll-run-code-in-reaction-to-scrolling-happening, I want to run a function when Fl_Scroll's yposition changes or stops changing. I did not find any callback or event that would help me with that.

In the end I solved my need by checking the yposition every 100ms but want to pick your brains for alternative / better solutions. Thank you!

Best regards, Jakub Holy
