I kept digging and figured this out (with the previously mentioned
sweetTitles integration):
class TooltipGeneratingPropertyColumn extends PropertyColumn
{
....
@Override
public void populateItem(Item item, String componentId, IModel
model)
{
super.populateItem(item, componentId, model);
String cellValue = ((RowMap)
model.getObject()).getValueAsString(this.getPropertyExpression());
if (cellValue.length() > 40)
{
String truncatedCellValue = cellValue.substring(0,40) +
"...";
// add code to override the value on the model with
truncatedCellValue here..... (model specific)
item.add(new AttributeModifier("showtooltip", true, new
Model("true")));
item.add(new AttributeModifier("title", true, new
Model(cellValue)));
}
}
}
