| Auto row height for images [message #1688846] |

Hi all,
I've a column which displays an image depending on data value (i.e., the
data from model object is a path which points to an image). I've created
a CellImagePainter which overrides the getImage method:
public class CellImagePainter extends ImagePainter {
@Override
protected Image getImage(ILayerCell cell, IConfigRegistry
configRegistry) {
Image retval = null;
Object dataValue = cell.getDataValue();
if (dataValue instanceof Image) {
retval = (Image)dataValue;
}
return retval;
}
This works as expected, but the image is higher than the default height
on rows and therefore it's cut. How can I achieve that the row is
automatically resized according to the height of the image? If I use
this construct (taken from Examples):
configRegistry.registerConfigAttribute(
CellConfigAttributes.CELL_PAINTER,
new PaddingDecorator(
new CellPainterDecorator(
new AutomaticRowHeightTextPainter(2), CellEdgeEnum.LEFT, new
CellImagePainter())), DisplayMode.NORMAL, PICTURE_CELL_LABEL);
the cell is painted a little larger (but not enough) with the text
representation of the image (i.e., "{Image 5654601516}"). This is not
very beautiful...
TIA,
Ralf.

Hi Dirk,
thanks for your fast answer. It works now as expected! NatTable rocks!!!
