Examples of com.google.gwt.user.client.ui.Widget.removeFromParent()

com.google.gwt.user.client.ui.Widget.removeFromParent()
Removes this widget from its parent widget, if one exists.
If it has no parent, this method does nothing. If it is a "root" widget (meaning it's been added to the detach list via {@link RootPanel#detachOnWindowClose(Widget)}), it will be removed from the detached immediately. This makes it possible for Composites and Panels to adopt root widgets.
@throws IllegalStateException if this widget's parent does not supportremoval (e.g. {@link Composite})

        if (lastIndex < 0) {
          throw new IllegalStateException();
        }
        Widget w = (Widget) uiObjectList.get(lastIndex);
        assert (w.getParent() instanceof HTMLTable);
        w.removeFromParent();
        lastIndex = -1;
      }

        while (++nextIndex < uiObjectList.size()) {
