All Implemented Interfaces:

ICellPainter

public class AutomaticRowHeightTextPainter
extends TextPainter

Special TextPainter that will always calculate the row height of the cell dependent to the content shown in the cell. It uses word wrapping and calculation of the cell height to support showing long texts in a single cell. It will grow/shrink the row height on resizing so always the optimal height is used for the row the cell resides.

This TextPainter should preferably be used for tables that use percentage sizing so the calculated row heights for example will grow/shrink correctly when resizing the composite that contains the table.

It shouldn't be used for large tables that can be scrolled as the growing/shrinking on scrolling can cause some side effects, like jumping layouts on scrolling.
