Reproduction: 1. Mac only: Select multiple lines in any of the Eclipse views which is a tree control: e.g. Outline, Debug, Variables, Breakpoints 2. Command-C to copy to clipboard 3. Run TextEdit 4. Paste Actual Results: The lines are pasted in the reverse order from the order in which they appeared in the original location. Expected Results: Should be in the same order. I tried Eclipse 3.2 on Windows; this did not reproduce there. So the bug is specific to the Mac version of Eclipse.
Have you tried 3.2 on Mac? This bug says the problem is in version 3.1.1. PW
It occurs in 3.1 and 3.2. I changed this to say 3.2. Thanks!
The root cause of this is that SWT's Tree.getSelection() explicitly says that the order of the returned items is unspecified. In practice, for Linux/GTK and Windows, the returned items are in order, and on the Mac, the order is reversed. Steve, any chance the API for getSelection() can be strengthened so that the items are returned in order? If not, all clients (or JFace) would have to sort the result of getSelection() themselves.
Regarding comment #3, "If not, all clients (or JFace) would have to sort the result of getSelection() themselves": I might be missing something because I'm not too familiar with this code, but I don't see how having the client sort the result would even be possible. E.g. let's say you are debugging, and you copy the callstack to the clipboard. If the "copy" code sorted the array of TreeItems, would it be an alphanumeric sort? If so, then that would reshuffle all the callstack entries into essentially random order. That would be an amusing effect :-)

Sorting is easy in cases where we already use a sorter (e.g., in the resource navigator where resources are sorted alphabetically). If we are just displaying a list of items in their natural order, sorting would have to recreate that natural order. I don't know what the behaviour on each of the platforms is so we need an answer from SWT. Theoretically, one could imagine a platform that returns the items in the order they were selected, but I don't know if such a platform exists.
Sorry Boris, this has come in before. We don't have control of the order in which the items in the selection are returned. On Windows, the order can vary as well (try deleting and adding items).

Sorry, you'll need to do it yourself. The order is not guaranteed in the operating system.
Fixed in SWT.
