TreeViewer only has small +/- buttons [message #464523]

I would like to create a Tree with similar style to the Eclipse package
explorer. On Windows XP this has nice big + and - symbols in front of
each icon. However, in my own tree

TreeViewer treeViewer = new TreeViewer(parent,
SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.BORDER);

the +/- symbols are 4 pixels smaller and look ugly. How can I get the
"big" buttons?

Thanks
Hans

The Eclispe package explorer is just using the default SWT Tree.
Are you running with a manifest?

If you are launching eclipse with java.exe and your application with
javaw.exe (or vice versa) you will need to have two manifests.

No, I just call it as another Eclipse window from Eclipse PDE. I dug
deeper and the +/- rectangles only have the correct size if the tree
icons show a certain icon, but the rectangles are too small with other
icons. I am really puzzled - both icons seem to have the same
characteristics (16x16 gifs etc) and I cannot identify what the random
behavior could cause.

Any other clues - this is really strange.
