public class ClickableSafeHtmlCell extends AbstractCell<SafeHtml> {
/**
* Construct a new ClickableSafeHtmlCell.
*/
public ClickableSafeHtmlCell() {
super("click", "keydown");
}
@Override
public void onBrowserEvent(Context context, Element parent, SafeHtml value,
NativeEvent event,
ValueUpdater<SafeHtml> valueUpdater) {
super.onBrowserEvent(context, parent, value, event, valueUpdater);
if ("click".equals(event.getType())) {
onEnterKeyDown(context, parent, value, event, valueUpdater);
}
}
@Override
protected void onEnterKeyDown(Context context, Element parent, SafeHtml value,
NativeEvent event, ValueUpdater<SafeHtml> valueUpdater) {
if (valueUpdater != null) {
valueUpdater.update(value);
}
}
@Override
public void render(Context context, SafeHtml value, SafeHtmlBuilder sb) {
if (value != null) {
sb.append(value);
}
}
And then usage:
Column<YourProxy, SafeHtml> nameColumn = new Column<YourProxy, SafeHtml>(
new ClickableSafeHtmlCell()) {
@Override
public SafeHtml getValue(YourProxy object) {
SafeHtmlBuilder sb = new SafeHtmlBuilder();
sb.appendHtmlConstant("<a>");
sb.appendEscaped(object.getName());
sb.appendHtmlConstant("</a>");
return sb.toSafeHtml();
}
};
nameColumn.setFieldUpdater(new FieldUpdater<YourProxy, SafeHtml>() {
@Override
public void update(int index, YourProxy object, SafeHtml value) {
Window.alert("You have clicked: " + object.getName());
}
});
