About windows
There are three main types of window you
will encounter when using the GUI:
• Parameter windows contain elements
(parameters) that you can select or edit,
such as options, lists, tick boxes, text
fields etc.
• Alert windows contain text that can be
a prompt or an error message.
Generally, this type of window will
contain a user-editable text field and OK
and CANCEL buttons. [All controls
inhibited until a button - CANCEL or OK -
is pressed.]
• Option windows have a number of
user-selectable options in the form of a
list, and may include OK and CANCEL
buttons.
Similar to a window found on a PC running a Windows-based operating system, the
window can be moved around the screen, which is useful if you need to see what is
behind it. Also, each window has a close (X) button at its upper-right corner.
>> To close a window
