Progress Bar when update settings

Tags: #<Tag:0x00007f0b02db7428>

Hello,
I was wondering if there is kind of “beforeUpdateSettings” hook.
I would like to do some cpu intensive computation on dataset (e.g. fibonacci) and while computing, show a progress bar while processing and then stop it.
I write this JFiddle: https://jsbin.com/venatid/edit?html,css,js,output

Thanks,
Best regards

Emanuele

We do not have any official preloader but I have UI for it https://jsbin.com/polopewuvi/1/edit?html,js,output
You should be able to show it via afterOnCellMouseDown event (as your calculations run after a click) and pause it with afterLoadDataevent.
