Is there a way to jump to a certain widget?

Hi there,

I am looking for a way to jump to a certain widget with the following scenarios or usage. "Jump" here means the application UI has this widget on focus.

1. The user is missing certain required data. I want to jump to the input widget missing the value when doing a custom form validation.

2. When the user selects some action (e.g. button, menu, etc.), and I update a certain widget on UI, I want to jump to that widget for the focus.

Is there a way to accomplish this? Any reference documents or URLs to explain this will be appreciated very much.

Thanks for your help in advance.
