Interface Focusable::setFocusable
Description
In BBj 6.0 and higher, setFocusable sets whether a control can be focused.
Note: A focused control is the control to which keyboard interaction is directed. Typically, the focused control is indicated visually, often via a dotted grey border. A control which is not focusable, therefore, cannot be manipulated via the keyboard. It is still possible to interract with a non-focusable control via the mouse. To disable all interaction, including the mouse, see setEnabled() and setEditable().
