Hi Kevin, I think we can go for option 1) and can approach the manual test as you outlined in your second comment. Attached please find an updated patch, which no longer contains the SWT upgrade but instead provides a respective comment within the manual test. I have also updated the manual test to provide detailed test steps and expectations, which were still missing in the initial patch.
I could get hold of a Windows PC with touch screen today and can confirm proper behavior there as well. Please note that while my patch contains handling of SWIPE events, I was not able to obtain any SWIPE events from SWT, neither on Windows 10 nor on MaxOS El Capitan, while PAN, ROTATE, and ZOOM events were properly delivered on both platforms (which is why I have excluded SWIPE from the manual test). I further noticed one difference of behavior on both platforms: while on MacOS SWT delivers inertia events for PAN, this is not the case on Windows (here, the gesture end event is always the last event that is delivered), but this is rather an SWT issue and cannot be handled by FXCanvas. Even while we go with option 1), upgrading the SWT library would not be a bad idea, as the version currently used (3.7.2) is from 2012. Maybe you could open a separate issue for it, which does not „block“ this issue but simply „relates“ to it?
