[REACT] pinch zoom on iOS

[calendardeveloper]

Is there a reason pinch zoom is not working on iOS Safafri? I dno't want to zoom in the time axis (controlled by zoomOnMouseWheel) - I just want to use the standard pinch/zoom in Safari on the iPhone. Looks like the event is disabled, maybe? Any ideas what might be going on?

Yes, we added a conversion of two finger pinch to an injected CTRL/mousewheel event. Scheduler, Gantt and Calendar DayView all zoom on CTRL/mousewheel.

I'll think about a way to make this opt-outable. In the meantime, using three fingers will still produce a pinch-zoom on iOS.

Ah, ok. Glad I asked the question here as I was banging my head on why it's not working!!!

How quickly can this be made configurable?

Not sure, but here's the ticket: https://github.com/bryntum/support/issues/8375

Hi, thanks for doing this. I can now pinch zoom on any area outside the scheduler. But within the scheduler rows/columns, I still can't pinch zoom. Any ideas why?

[calendardeveloper]

Any updates here please?

Hey calendardeveloper,

Sorry for the late reply. Are you able to share a screen recording or some instructions on how to reproduce the behavior that you're describing?

[calendardeveloper]

e.g. on your iPhone, go to this example https://www.bryntum.com/products/scheduler/examples/bigdataset/

now try to pinch zoom on the top bar, where the title is (Big data set demo), the zooming will work.

now try to do the same within the scheduler rows (you won't be able to)

It's converted to a sequence of CTRL+wheel events so that our existing zooming works. There is a global opt-out config in the Widget class: https://www.bryntum.com/products/scheduler/docs/api/Core/widget/Widget#property-convertPinchToMousewheel-static

I tried setting this property on the scheduler config and it made no difference, unfortunately. Is there an example of this somewhere please?
