If it happens in hosted mode, put breakpoints inEvent.NativePreviewEvent.cancel() and DomEvent.preventDefault() and DomEvent.stopPropagation() (and/or eventually the two similarly named methods in NativeEvent) and look at the call stack when they're hit.

Re: How to debug whats grabbing my click events?
Ah, yes, thanks for the link. But in my case I'm not actualy doing dom
manipulation of anything event-related.
I was just trying (and failing) to use the Dom to work out why my
links wernt fireing when clicked.
Something is blocking my links, allthough the mouse cursor changes so
it seems to be no panel in front of it.
Interestingly, the right-click functionality of Firebug
(Richtclick>>Inspect Element) also dosnt work with it.
In fact, the right click menu dosnt show up at all when the mouse is
over this panel O_o
I'll keep debuging, but it would be really helpfull if there was
someway to narrow down what widget could be causeing it.

Re: How to debug whats grabbing my click events?
I too could use some general advice on how to debug event-related
problems, including DOM events.
You might find some of the responses in this other thread useful - the
question I posed there is different, but closely related. Essentially,
though, the message I took away was to avoid manipulating the DOM
directly with anything involving events. One of the responses points
to a page that describes some of the event/DOM/browser issues of
relevance.

Re: How to debug whats grabbing my click events?
Anyone? I'm still having trouble working out what widgets grabbing my
clicks.
Not sure if Ben's having the same trouble as me, but there must be
some method to work it out no? (using Firebug, debuging
code...anything?).

Re: How to debug whats grabbing my click events?
Update: I'm using a NativePreviewHandler to get a sense of what is
going on ... but can't seem to get much useful information.
Event.addNativePreviewHandler(new NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent event) {
NativeEvent ne = event.getNativeEvent();
if ( ne != null && ne.getButton() == ne.BUTTON_LEFT ) {
GWT.log(ne.getType(), null);
}
}
});
This logs twice when I left-click: mouseup then mousedown
I'd really like to figure out why my Widget's ClickHandler is not
getting called, but don't know how to go about investigating (or
fixing this). Any advice?

Re: How to debug whats grabbing my click events?
I too would like to know how to debug event-related problems? In my case, I dynamically insert an Element into a TreeItem, via DOM manipulation, in order to display an editing control for the selected tree node. This worked well using GWT 1.4.62, but no longer works using GWT 1.6.4. It looks like the tree nodes are represented by a different DOM/HTML structure in the new version, so I made changes to accomodate this (somewhat). But a serious problem remains: no ClickEvents are registered on the Element that I insert into the DOM. I've tried to debug this by inserting an HTML element explicitly set to have a hyperlink with a javascript href value to pop up an alert box. The link appears, and on mouseover the browser status bar shows javascript:alert(), but on click nothing happens. Any tips for how to debug such a situation? Any tips for how to insert Elements via DOM manipulations and still have them participate in event handling, i.e. click events? Thanks!
