I want to share with you what I took from the example. and to show how I
implemented it.
The example that Igor gave shows how to toggle a row. I needed a single
selection.
So:
public class HighlitableDataItem extends Item {
private static final long serialVersionUID = -1637144139412425548L;
private boolean highlite = false;
public HighlitableDataItem(String id, int index, IModel model) {
super(id, index, model);
setOutputMarkupId(true);
add(new AttributeAppender("class", true, new Model("highlightItem"),
" ") {
private static final long serialVersionUID = 1L;
@Override
public boolean isEnabled(Component component) {
return isHighlite();
}
});
}
public void setHighlite(boolean highlite) {
this.highlite = highlite;
}
public boolean isHighlite() {
return highlite;
}
}
In the table:
/**
* Enable the user to have rows that can be highlighted
*/
@Override
protected Item newCellItem(String cellItemId, int index, IModel model) {
return new HighlitableDataItem(cellItemId, index, model);
}
And here's the method that is called when the AjaxLink (in the table) is
clicked:
private void itemClicked(final HighlitableDataItem clickedItem, final
AjaxRequestTarget target) {
ownersTable.visitChildren(HighlitableDataItem.class, new IVisitor()
{
public Object component(Component component) {
HighlitableDataItem traveresedItem = (HighlitableDataItem)
component;
if (traveresedItem.isHighlite()) {
traveresedItem.setHighlite(false);
target.addComponent(traveresedItem);
return traveresedItem;
}
return null;
}
});
clickedItem.setHighlite(true);
target.addComponent(clickedItem);
}
I think I will create a visitor class exactly for that...
