Ok so the problem was that I missed the part about letting the table
view know it should allow external drag operations... :)
In the initialization code I added:
@applicationsTableView
.setDraggingSourceOperationMask_forLocal(OSX::NSDragOperationGeneric,
false)
And now it works great. Dragging a row onto a texteditor opens the
file at the path I return in
tableView_writeRowsWithIndexes_toPasteboard.
Cheers,

Hi,
I'm still very new to all the DND stuff, so here goes:
I want to be able to drag an item from my table view onto, for
instance a texteditor, and have it open the file that the item
represents.
(Also having it drop on Terminal and inserting the path to the file
would be nice, but that might be something completely different.)
Some stuff I tried in my table view data source is (RubyCocoa code
btw):
def tableView_writeRowsWithIndexes_toPasteboard(tableView, rows,
pboard)
pboard.declareTypes_owner([OSX::NSFilenamesPboardType], self)
pboard.setPropertyList_forType(['/etc/hosts'],
OSX::NSFilenamesPboardType)
true
end
OR:
def tableView_writeRowsWithIndexes_toPasteboard(tableView, rows,
pboard)
url = OSX::NSURL.URLWithString("/etc/hosts")
pboard.addTypes_owner([OSX::NSURLPboardType], nil)
url.writeToPasteboard pboard
true
end
So the drag operation is initiated, but that's only because I return
true.
Most stuff I read about dragging from the tableview is about
promising files,
which, if I understand it correctly, is not what I need.
Does anyone know where in the docs I should RTFM?
Or a OSS app or example that implements such behaviour?
Kind regards,
Eloy
