Trackpad gestures broken

[olibclarke@…]

The following bug report has been submitted:
Platform:        Darwin-18.7.0-x86_64-i386-64bit
ChimeraX Version: 0.91 (2019-07-31)
Description
Hi,

The trackpad gestures are no longer working in the latest nightly of chimera. A two finger swipe now zooms, rather than rotating, and a three finger swipe does nothing, rather than translating the molecule.

Cheers
Oli

2 and 3 finger drag are working fine for me in the current daily build (Aug 1, 2019). None of that code has changed recently. Are you sure you do not have "Trackpad gestures to rotate and move" turned off in ChimeraX Preferences, Trackpad tab? Also the ChimeraX window probably has to have the focus for it to get the multi-finger drag events -- ie you can't have your web browser with the focus and rotate the molecule -- actually testing shows that is not true -- 2-finger drag works even in that case, although 3-finger drag does not (must be somehow intercepted by the web browser).

Hmmm - it was not working (and I checked that I had the correct preferences set), but I have just restarted it again and it is working correctly now - my apologies, must have been a temporary glitch.

Cheers

Ok. There is probably some real Qt problem lurking. Let me know if it happens again.
