I was able to get the onclick even to work, but there seems to be a delay. The event will not trigger more than once every few seconds. I have looked at the documentation and there seems to be a delay setting for the listener. I have included my checkbox definition code and was wondering if there was an easy way to disable the delay.
The unchecked function just does a msg box right now. What I want to accomplish is every time the checkbox is unselected, I want an "are you sure?" msg box. But because of the delay, the msg box does not always pop up. Am I doing the wrong thing, is there a better event to use? Any help would be appretiated.
Thanks,

You'll need some extra plumbing.
Example:
new Ext.form.Checkbox({
listeners: {
check: function(checkbox, checked) {
if (checkbox.skipConfirm) {
delete checkbox.skipConfirm;
return;
}
if (!checked) {
checkbox.setValue(true); // undo uncheck
Ext.Msg.confirm('Confirm', 'Are you sure?', function(btn) {
if (btn == 'yes') {
checkbox.skipConfirm = true; // without confirmation
checkbox.setValue(false); // uncheck
}
});
}
}
}
});
The beforecheckchange event is for checkItem, not checkbox. There are a few other "before" events i could try, but the onClick is a built-in listener. I am new to ext, so how would I add a custom listener? What would I need to add to my code to insert a new listener or change the delay? Some sample code would be nice.
Try using the beforecheckchange event. Check out the documentation to read about it.
