If the COLUMN-SCROLLING attribute is TRUE, horizontal scrolling for the browse widget moves in whole-column increments. If a column is wider than the browse widget, you cannot see the text if the right side of the column, but you can still scroll to the next column.
If the attribute is FALSE, horizontal scrolling for the browse widget moves in increments equal to the pixel width of the average character in the current browse font. In this case, if a column is wider than the browse, you can view it by scrolling through the column in these increments.
The default value is TRUE for a static browse, and FALSE for a dynamic browse.
