I tried to create my own custom ImageLoadingCell but I have a problem to
get any Browser Event fired.
My custom cell extends AbstractCell<MyItem> and if I overwrite the Browser
Event method. E.g.:
@Override
public void onBrowserEvent(Context context, Element parent, ActivityItem
value,
NativeEvent event, ValueUpdater<ActivityItem> updater) {
Window.alert("browserevent!");
}
the alert-box will never called.
I also called in the constructor e.g.:
super(BrowserEvents.CLICK);
to listen for click-events. But nothing happens If I click.
As I said before, I use mgwt CellList. The mgwt-CellList does not need the
" extends AbstractCell<MyItem>", it needs " implements Cell<MyItem>" and
it's own render method. I think there is no event support implemented.
(https://github.com/mgwt/mgwt/blob/master/src/main/java/com/googlecode/mgwt/ui/client/widget/list/celllist/CellList.java)
How can I achieve it to listen on events to get notified if an Image could
not be loaded correctly? So I could replace it with a default image.
