Hello:
The real question is: I have a widget to inherits of ComplexWidget with the
following declarations:
private Element root = Document.get().createDivElement();
private LayoutPanel header = new LayoutPanel();
private Image imgUp = new Image(getDefaultResources().imageUp());
header.add(label);
.....
.....
root.appendChild(header.getElement());
.....
.....
setElement(root);
sinkEvents(Event.ONCLICK);
Now I add a domHadler for image (the only event that interests me), but,
sinkEvents(Event.ONCLICK) register the event at level of element root, I
don't know how propagate the event at image, so that only the image, treats
you, and not the other elements of the widget.
I made this:
imgUp.addDomHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
header.setWidgetTopHeight(imgUp, 0, PX, 0, PX);
header.setWidgetTopHeight(imgDown, 0, PX, 30, PX);
collapsed = !collapsed;
collapseBody(collapsed);
}
}, ClickEvent.getType());
But entire the widget treats the event.
Any idea?
