[news.eclipse.platform.swt] Re: TableColumn pack problem

["Steve Northover" <steve_northover@xxxxxxxxxx>]

Sigh.  I've gotten to the bottom of it and have yet to decide whether it is
an SWT bug or the correct (unwanted) behavior.  The problem is that
Column.pack() for the last column is not taking into account the space for
the scroll bar.  When you call shell.pack(), this eventually makes the table
grow the extra space for the scroll bar ... and so on.  How dead are you?
It may be a while until I get to this again.
