I think you should set implement as array:
qx.Class.define("scqx.ui.form.TextField",
{
extend : qx.ui.form.TextField,
implement : [scqx.ui.form.DataComponentIf, ...] //define an array here

Betreff: [qooxdoo-devel] Check an object for an implemented interface
Hi All,
I have a problem with checking an object for implementing an interface.
I have a class which
implements an interface:
qx.Interface.define("scqx.ui.form.DataComponentIf",
{
...
qx.Class.define("scqx.ui.form.TextField",
{
extend : qx.ui.form.TextField,
implement : scqx.ui.form.DataComponentIf,
...
Following method should only register components which implement the
interface:
add : function(component) {
if (qx.Class.implementsInterface(component,
scqx.ui.form.DataComponentIf)) {
this.__dataComponents[this.__dataComponents.length] =
component;
}
arguments.callee.base.apply(this, arguments);
},
But the interface is not detected. I've also tried to get the
implemented interfaces using
qx.Class.getInterfaces() but I got an empty array as result.
What's wrong?
Thanks.
Lutz
