The sliders do not work with touch in p5js. I am using Safari on an iPad Pro. I have no problem using sliders in other guis, and the built in p5js sliders work fine as well.

Thanks for replying, Peter. My iPad Pro generates mouse and keyboard input which works with every browser I have tested - Safari, Chrome, Firefox etc. I have also used many GUI libraries such as OPC and dat.GUI. Never a problem with sliders. I think your library looks very cool and would like to use…

Ok. I will give up on using it, and stick with OPC, which is well-supported on Open Processing. Thanks anyway.

I believe the issue is not with OP or with iPad rather it is that canvasGUI does not process touch events. I created canvasGUI because I wanted to learn JavaScript and I wanted a meaty project to get my teeth into. Unfortunately I have no experience programming touch events and I had enough to get …

[image] quark: Perhaps it is time for me to revisit canvasGUI and touch events … I decided to make this a priority because it severely affects the usability of canvasGUI. Also I do like a challenge. :grinning: To make canvasGUI transparent to the user it attaches its own event listeners to …

That is great news, Peter. I will look forward to incorporating CanvasGui into my new sketches. Richard

All fixed :grin: see the announcement here

Thanks, Peter. Will you let Sinan Ascioglu know about the new version? He could add it to the current library selections on Open Processing. I can let him know if you prefer. Also do you have a link to import the new CanvasGui version?

[image] rbytes: I can let him know if you prefer. Yes please. This link might not work because it is not a secure https link http://www.lagers.org.uk/libs/canvasgui/0.9.5/gui.min.js

I was so focused on sliders and ranges I forgot to include touch events for the other controls :innocent: I have rectified this with version 0.9.6 which also fixes a bug from 0.9.4 when using multiple sketches with GUIs on the same web page (example of what I mean here ). So use V0.9.6 :+1:

The new library works perfectly. You were correct that the link http://www.lagers.org.uk/libs/canvasgui/0.9.6/gui.min.js was not accepted by OP. I had to follow the link, copy the library code and paste it into a new tab. Do you have plans to give it an https link? Thanks, Peter.
