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

Thank you all!

> Is it not possible to subclass your own scroll and then, in the handle method, simply check for the user releasing the mouse button drag?

I guess it is though I would also need to check for KeyUp (scrolling with keybord arrows) and MouseWheel (scrolling with mouse).

Thank you very much for the code, Karman! It looks neat though I have yet to fully understand it :) And I wonder what is the purpose of the boxes you draw in the constructor?

PS. After scrolling I check with a time out if another scroll happens, if not I execute my code. So you don't need repetitive timeouts.

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
