floating point column width misbehaves in WTreeView
From Guy Deleeuw:
Another annoyance : when I resize a column into a WTreeView with a double value like 142.800003 I see only two columns 0 and 1 the 2 to 12 are not rendered.
If I convert this value to a long before the call to the setColumnWidth in this case all work fine.
I check the doc but WLength take a double as parameter
