There is an issue posted for adding a keyboard listener to the
document here:
http://code.google.com/p/google-web-toolkit/issues/detail?id=1442
Based on the GWT team response to that issue, I would assume that
there is not going to mouse listener support for the entire document
anytime soon.
Whenever something doesn't have a good api yet in GWT, you can always
roll your own with JSNI. Something like this would be my approach:
public class MousePosition {
public static int x,y;
private static MouseMoveEvent mouseEvent; //from
com.google.gwt.event.dom.client.MouseMoveEvent
public static void setMouseEvent(MouseMoveEvent e){
mouseEvent = e;
x = mouseEvent.getX();
y = mouseEvent.getY();
sliqueJS.log.info("latest mouse event position (X,Y) = "+x
+","+y);
}
public static native void trackMousePos() /*-{
$wnd.document.onmousemove =
@com.slique.input.MousePosition::setMouseEvent(Lcom/google/gwt/event/
dom/client/MouseMoveEvent;);
}-*/;
}
Unfortunately, code is spewing an error I don't recognize. Can anyone
else tell what's going on here?
