Treeviewer losing expand/collapse boxes when jarred [message #485783]

I have an app using a TreeViewer. It works fine and I can programatically
expand and collapse the tree to various levels but when I jarred it up it
loses the plus/minus boxes on the branch corners!
Has anybody seen this before? Got any suggestions?
I am using Galileo, SWT 3.5 and Java 1.6.0 on Windows XP.

Thanks!

Hi,

This definitely should not happen. My only guess is, in the jarred case are
you using swt's WPF port instead of its win32 port? If I remember
correctly, the Trees in WPF (and also on Vista in general) do not show their
expand/collapse icons until you hover over the Tree.

Grant, thanks for the reply. I looked at swt.jar, and I am using win32.
Internally, it says it is version 3.5.5.
Unfortunally there are other funny things going on... My label provider
for the tree is supposed to put a specific image in front of the label
under certain conditions ( a red circle). Well it is doing it for all
labels and it is not the circle it is a square! I will poke around some
more, do some more logging and see if I can discover anything.
Thanks.

I assume that the swt jar's version is 3.5 (the latest release), not 3.5.5
(doesn't exist). If it's really 3.5.5 then perhaps you're not using swt
;-).

The red square probably indicates that the file with your image is not being
found.
