Heres my example (a custom widget):
public class TestWidget extends Composite {
private static TestWidgetUiBinder uiBinder = GWT
.create(TestWidgetUiBinder.class);
interface TestWidgetUiBinder extends UiBinder<Widget, TestWidget> {
}
@UiField
Button button;
public TestWidget(String firstName) {
initWidget(uiBinder.createAndBindUi(this));
button.setText(firstName);
super.onAttach();
}
@UiHandler("button")
void onClick(ClickEvent e) {
Window.alert("Hello!");
}
}
And here the code to add the Widget to a Panel:
TestWidget testWidget = new TestWidget("myTestWidget");
RootPanel.getBodyElement().appendChild(testWidget.getElement());
mainPanel.getElement().appendChild(testWidget.getElement());
I know that it is possible to add an Widget directly to an RootPanel
like this:
RootPanel.get("myId").add(testWidget );
However lets say i want to add widgets directly to the DOM. I don't
really understand why i have to call super.onAattch(); to get my
ClickEvent to work. If i don't execute that line it won't fire. I'm
not sure if this is the right way maybe somebody can give me more
information.
