Syed:
Not sure if you ever got around to it. A few strategies can be used
here. I wasn't able to find something out of the box to do it.
However, a few approaches can be used in this case. I took what I
thought would be the easiest/fastest to illustrate how to accomplish
it.
Essentially, I am wrapping the TreeItem's with a FlowPanel and playing
with the CSS properties a bit. You can add the logic that you need and
use something similar for only the nodes you want.
Tree tree = new Tree();
String items[] = {"Uno", "Dos", "Tres"};
for (String item : items) {
TreeItem topitem = tree.addItem(item);
InlineLabel label = new InlineLabel("Hoja - " + item);
label.getElement().getStyle().setOpacity(0.5);
FlowPanel layer = new FlowPanel();
layer.getElement().getStyle().setCursor(Cursor.AUTO);
layer.add(label);
topitem.addItem(layer);
}
Best regards,
Alfredo
