can_focus - Can focus control area

Usually, data controls like edit or list controls allow focusing the control area by using the tab key. When, however, defining embedded forms, usually the next data control is expected to receive focus when using the tab key. Hence, embedded windows usually do not enable this option. So far, only scroll areas might behave in two different ways. Setting the option to true allows focusing the scroll bars by using the tab key. Setting the option to false will set the focus to the next control that can be focused by the tab key (usually a data control).
