[This question is in relation to this question]
Setting: I have this home-crafted "editable label" component which looks like a label, but when you click it, it turns into an editable field, allowing you to edit it. You can hit Esc to cancel, or Shift-Enter to OK your edits - or click the respective buttons beneath the editable field.
The Challenge: When hitting edit, I want the entire UI to be "whited out", except for the edit-label's area, to clearly denote to the user where it is expected that he should focus.
Alternative, this could be achieved using the JXLayer project. Take a look at some of their demos where they blur out the GUI when an item is selected. You would have to implement your own JXLayer view in order to white out your GUI.

Demos are under the "getting started" item on the front page.
