Question

I added click handler to flowpanel as follows

this.addDomHandler(new ClickHandler(){

            @Override
            public void onClick(ClickEvent event) {



                Window.alert("event.getX()="+event.getX()+" event.getY()="+event.getY());
                Window.alert("event.getClientX()="+event.getClientX()+" event.getClientY()="+event.getClientY());

            }

            },ClickEvent.getType());

… as I could get it getX() returns mouse position within flowpanel but getClientX() returns another value and I couldn’t get the value is coming from. So my question is what is the getClientXY() methods are used for?

P.S
GWT 2.2/2.3

Answer 1

The javadoc is clear:

getClientX: Gets the mouse x-position within the browser window‘s client area.

getX: Gets the mouse x-position relative to the event’s current target element.

So, you can use getClientX to get the absolute left position of some element.
