I've a CellTable to which I attach a click handler(via addDomHandler). Then I've added a custom cell which handles onBrowserEvent(...). I'd like to stop the event to propagate in the cell's onBrowserEvent so that the table handler is not invoked anymore. Is this possible?
table = new CellTable();
table.addDomHandler(new ClickHandler() {
@Override
public void onClick(final ClickEvent pEvent) {
Trace.info("this shouldn't trigger");
}
}, ClickEvent.getType());
table.addColumn(new IdentityColumn<MyVO>(new MyCell()));
class MyCell extends AbstractCell<MyVO> {
@Override
public void onBrowserEvent(com.google.gwt.cell.client.Cell.Context pContext, Element pParent,
Handle<DnSuggestionDetailsVO> pValue, NativeEvent pEvent,
ValueUpdater<Handle<DnSuggestionDetailsVO>> pValueUpdater) {
Trace.info("cell onBrowserEvent handled, propagation should stop here!");
pEvent.stopPropagation();
}
}
Thank you!
It's easier to cancel an event before it reaches the cell:
table.addCellPreviewHandler(new Handler<Item>() {
@Override
public void onCellPreview(CellPreviewEvent<Item> event) {
//do something
event.setCancelled(true);
}
});
Note that CellPreviewHandler already monitors all events within a table. You can use it for your ClickEvent as well (with finer control like which column is clicked) instead of adding a ClickHandler to the entire table.
