  • Method Details

    • isFocusable

      Boolean isFocusable()
      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.
      Returns:
      True if object can be focused, False if not.

      Parameters:
      focusable - Boolean True for allowing focusing, False to disable focus
