Re: [platform-swt-dev] Mac OS 10.4 Finder drag and drop development
|
Thanks for investigating Eric. Please add your findings to the bug and I
will have a look at it. Interacting with the Finder seems to be a bit of
black magic - as noted in the Apple Documentation TN1085: "Dragging
flavorTypeHFS data from your application to Finder has always supposed to
have been possible. However, Finder bugs have prevented most applications
from successfully using this feature." I will look again at the
AppleEvent issue described in this tech note. Maybe there is new
documentation with Tiger that will help.
I will see what I can do for you. First things first, I will get my hands
on Tiger - still living in the Panther world myself.

Ok...I spent today messing around with the latest build and your new
data promise implementation....it did not solve anything for me but made
me understand the problem with drag source. When you add drag flavors
in DragSource.java you cannot just index the item reference every time
you add a drag flavor. This item reference should ONLY be changed for
each unique item being dragged. So if you change drag source (Working
of the R3.0 tree) to reset the index right before you cycle through the
flavors then each drag item DOES get a single unique reference
identifier and drags from an SWT application to the finder work great.
My guess is that this bug has been in the DND on Mac since the beginning
since there has always been inconsistent behavior.
My guess on the furl source was correct also...this needed to be
implemented for the finder to accept a drop.
I am not sure how you can reconcile this issue with your new DND code
that has promised flavors since you have no idea how many items are
being dragged (funny...there is even a comment in the code about that :-).
Anyway...I am going to get my code cleaned up, test against 10.3 and
then submit the code under bug #93619
Not exactly sure why this bug has normal priority while an intermittent
slowdown bug on tiger has blocker priority??? Seems like random
priorities to me....guess it's who you know ;-)
Thanks,
Eric*
