This property applies a line break on the text of the header of columns of an E3Browser, allowing to display the full text of a column's name. That line break is applied only where there is a space, a tab, or a forced line break on the text. Configuring this property in True does not change the value of the FixedRowHeight property, which controls the height of column headers. In case the text of the header does not contain spaces, tabs, or forced line breaks, that text is truncated and an ellipsis is displayed on the limit of the column's width. In addition, the vertical alignment of the text, which is usually centered, is changed to a top alignment. The default value of this property is False.
