Get widget variable name from event?

[membersound]

Hi,

is it possible to retrieve the name of an element that triggers an event?
For example, if I have a FocusPanel which triggers a MouseOverEvent, can I get the variable name of that panel somehow from the event?


@UiField
FocusPanel panel;

@UiHandler("panel")
void mouseOver(MouseOverEvent ev) {
    Window.alert("you clicked the element named 'panel'"); //how could I use the 'ev' to get the name 'panel'?
}

No you can't.

All you can do is

Object source = event.getSource();

if(source == panel) {

  //event fired by specific panel

}

But this only makes sense if you have multiple event sources for a single method, e.g.

@UiHandler({"panel1", "panel2"})

void onMouseOver(MouseOverEvent event) {

  //dispatch event source here.

}

The above code is pretty much the same as

MouseOverHandler handler = new MouseOverHandler() { //implement... }

panel1.addMouseOverHandler(handler);

panel2.addMouseOverHandler(handler);
