[news.eclipse.platform.swt] Re: showColumn() bug?

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

Hi Tim,

I've logged https://bugs.eclipse.org/bugs/show_bug.cgi?id=112463 , and tried
to add you as a CC but couldn't because bugzilla did not know of your email
address.  Interestingly I see the opposite problem to what you describe (my
snippet shows it failing when the column's LEFT edge is out of view).  I
added a second comment to the report specifying that both cases should be
checked.

Regarding workarounds, I can make my snippet in the bug report show column 2
by first showing column 1 and then column 2 (so just add
"tree.showColumn(column1);" as the first line in the Button selection
listener).  On win2000 this did not show any extra flash for me.  It's just
an idea, as I can't think of any other workarounds at the moment.
