Re: Get widget variable name from event?

[Jens]

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);

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'?
}
