Hi everybody,
I am trying to change the image of an image cell on click.
My code looks like this:
final TrafficLightCell imageCell = new TrafficLightCell();
Column<Somewhat, ImageResource> potentiallyAffectedColumn = new
Column<Somewhat, ImageResource>(
imageCell) {
@Override
public ImageResource getValue(Somewhat object) {
return resources.blank_bubble();
}
};
potentiallyAffectedColumn.setFieldUpdater(new
FieldUpdater<Somewhat,
ImageResource>() {
@Override
public void update(int index, Somewhat object,
ImageResource value)
{
imageCell.render(null,
resources.green_bubble(), new
SafeHtmlBuilder());
}
});
This traffic light cell catches onclick events. I thought i may change
the image via render method but it obviously does not work. Can
someone give me a hint how to handle this?
