Interface Focusable::isFocusable

Description

In BBj 6.00 and higher, isFocusable returns a value indicating whether or not the user can focus the control.

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 interact with a non-focusable control via the mouse. To disable all interaction, including the mouse, see setEnabled() and setEditable().
