| /** |
| * Special {@link 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. |
| * |
| * <p>This {@link 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.</p> |
| * |
| * <p>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.</p> |
