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 are
inhibited until one of these buttons is
clicked or the window is closed).
• Option windows have a number of
user-selectable options in the form of a
list, and may include OK and CANCEL
buttons.
