Event handlers on children of toolbarbutton

[Susan Crayne]

In an existing application that I'm modifying, there is a toolbarbutton that
has a click handler on it. I'd like to change that so that instead of the
handler on the toolbarbutton, there is a handler on the label element that
is the toolbarbutton element's first child. I've tried to do this, and the
label element does not receive the click event. I'd like to know if this is
possible. If it isn't, I can change the xul so that there is, instead of a
toolbarbutton, a box with explicit label and image children. Thanks.

According to this:
https://developer.mozilla.org/en/XUL/label
and a couple of books I have, the label element doesn't support
onclick or related handlers.

I looked at the page for which you gave a link, and it does not say that the
label element does not support onclick or related handlers -- in fact, I saw
this:

Inherited Methods
addEventListener, appendChild, blur(), click()

Is there other information that you know of that contradicts this?

What you tried to do should be possible (if I read you prose correctly).

Thanks -- that's very useful info.

I went back and gave the label docs on the MDC page another read. You
were right/I stand corrected; the inherited ability to use handlers
are there. This bit of quick code worked on all the labels I could
think of (toolbars, forms, etc):
<label value="Test" onclick='alert("test");'/>

Would that do or is it too simple?

FWIW - I've gone through a couple of my books on XUL and all discuss
using buttons of one sort or another with handlers. None discuss
using handlers with labels or list options for handlers with labels.
Granted documentation for XUL is pretty mediocre at best, but I can
understand where the authors may be coming from on this. The
"conventional wisdom" would state that buttons are where handlers are
intended to be; labels are just just there for info purposes only.

What I was trying to do was put a click handler on the label child of a
toolbar button when the toolbar button was defined in XBL. This did not
work -- I needed to replace the toolbar button with a vbox that had image
and label children.

You would need to set allowevents="true" on the label element. (Normally
a button disables events on its children.)
