You would think that would be the syntax, but it's not. Inside the braces,
the 'this' keyword actually refers to the child object, not the parent. So you
can do something like this:
object.forEachChild(function()
{
try
this.setValue('');
catch(e)
{;}
}
Again, this would only clear the immediate children, not the children of a
child. But since you know which objects contain the edits then you should have
no trouble clearing them with the above syntax.

Thanks Jim, I really appreciate the help you've been giving me this last
few days!
I actually found forEachChild in the API earlier and gave it a go, but
after your post I see where I went wrong. All the fields are on 3 splitpanes
(labels on the left, fields on the right), and each split pane is on it's own
TabViewPage.
So I will have to do this locally rather than a general function me thinks.
Just to clarify the use of forEachChild. Does this look right?
object.forEachChild(function(e) {
e.setValue('');
});
Cheers

A brute force way would be to iterate each child control of the window
(assuming that you are placing your edit controls on the window itself and not
on some other control in the window) using forEachChild and then issue a
setValue('') on each child (wrap this in a try/catch because not all qooxdoo
controls have a setValue() method.
This is a brute force way but it will work. If you don't like the
ugliness of the try/catch, you can add a method to the qx Object as an empty
method (that way all controls can call the method but only ones that you create
code for will actually do something). Then in your edit control, override the
method with code to clear the value. Then you can also write a method of Object
that iterates all children and all their children and calls this new method for
clearing the value. Then you can make one call to the window to clearValues and
everything gets cleared.
I give you this cryptic answer to get you started, you always learn more
from working out the code yourself. If you are having trouble with the concepts
or with implementing it, let me know and I'll give you some actual code (I do
this sort of thing in my app, the code not the withholding of information :-)
).

Is there an official way to reset all fields on a qooxdoo 'form'?
I have a window for data entry, when the user clicks the 'Save' or
'Home' button, the data entry window closes, and the Home window opens again.
If you navigate back to the data entry window, any data typed before is
still there.
Obviously the windows for this app are loaded from the start, and are
only closed when not needed. Rather than being totally destroyed and reloaded
each time.
Would using window.dispose() be a better option to get what I'm after?
And what does window.restore() do exactly?
I ask as I've tried the above method (dispose/restore) unsuccessfully.
If manually coding each feild and setting the value to blank when the
window closes is the only way then I'll do that, but I was hoping for something
more like document.getElementsByTagName or the like as there are over 30
fields, it'd be nice just to have a loop.
