Hi,
as chris said, the easiest way is to add a listener to each added element.
For that, you can subclass the qooxdoo form and extend its methods. I have
tested it in the playground and it works like this:
qx.Class.define("MyForm", {
extend : qx.ui.form.Form,
properties : {
dirty : {
check : "Boolean",
init : false
}
},
members : {
add : function(item, label, validator, name) {
this.base(arguments, item, label, validator, name);
item.addListener("changeValue", this.__onChangeValue, this);
},
__onChangeValue : function() {
this.setDirty(true);
},
reset : function() {
this.base(arguments);
this.setDirty(false);
}
}
});
This works for all added item supplying a value property. Most of the
qooxdoo widgets do have a value property. Only those handling a selection
does not have that so you need to extend the code I gave you if you want to
use a SelectBox for example.
Best,
Martin
