For #1, I think some clarification and detail is needed as to what classes you're using and what you expect to see when focused.
Hi keville,
Thank you for your answers.
I am applying a project on FullScreen so the classes is used usually which are KONtx.system.FullscreenView, KONtx.element.Container. I do not expect to see when focused, but I only expect to catch event of focus when can change a image from blur status to focus status. Can I do this? If is ok, how can I do? :)Hoa Tat.
