Treeviewer Scrollbar vanishing act [message #523919]

While working with Treeviewers, I stumbled on an interesting issue and wondered if anyone else has seen this/knows a work around:

If you create a TreeViewer (or even a Tree) with over 65535 elements (the length of a short) and then expand them all, the vertical scroll bar disappears.

I've been digging pretty deep trying to find where/why this might be happening, but so far I haven't found much. Should this be reported as a bug? Or is there a simple work around that I should be using?

Thanks,
-Ritter

Hi Ritter,

sounds a lot like a bug to me. Could you produce a snippet that shows the problem similar
to that one:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet15.java?view=co

and file a bug for the Platform > SWT component?

Greetings,

Ralf
