Hi, Thanks, I’m looking at it now.
I’m a bit confused over the keyboard handling. I would have thought that the processing would take place on the KeyUp event, but it seems like its occurring on the KeyDown event which is where I am going wrong. I’m not sure what use NSKeyUp is in this case? The other thing is that a KeyDown with the AutoRepeat flag == YES seems to imply a an NSKeyUp? IOW, the events I see are: NSKeyDown Repeat == NO NSKeyDown Repeat == YES ) If the Key is held down….. NSKeyDown Repeat == YES ) NSKeyDown Repeat == YES ) NSKeyDown Repeat == YES ) NSKeyUp Repeat == NO All the Best Dave > On 18 Jul 2016, at 13:05, dangerwillrobinsondan...@gmail.com wrote: > > You might review the Event programming guide (especially the part about short > circuiting) and the responder chain. > That will pull this together in some detail. > > Sent from my iPhone > >> On Jul 18, 2016, at 7:57 PM, Dave <d...@looktowindward.com> wrote: >> >> Hi Alastair, >> >> Thanks a lot for this - it makes my life harder but at least I know how it >> works now. >> >> All the Best >> Dave >> >>> On 17 Jul 2016, at 21:03, Alastair Houghton <alast...@alastairs-place.net> >>> wrote: >>> >>> On 17 Jul 2016, at 14:06, Dave <d...@looktowindward.com> wrote: >>>> >>>> My question is, do the keyboard and Mouse Down Events come in pairs, so >>>> that the following would/should not occur: >>> >>> No. KeyDown happens when the key goes down, KeyUp happens when they key >>> comes back up.
