Create a List. A List has several
parts to it:
-ListModel: Contains the data which is to be

as shown below
-ListCellRenderer: Creates the Components to
be used within the List (the default
setting is to create Labels using
the desired text).
-ListSelectionModel: Determines how
the List may be selected.
To add values to the list:
First, create SFStrings and use the
.setValue("Value") function to set their
values. Then, use the .pushBack(&SFStringName)
to add them to the List.
Next, create the CellRenderer and ListSelectionModel
defaults.
Finally, actually create the List. Set

Determine the SelectionModel
-SINGLE_SELECTION lets you select ONE item
via a single mouse click
-SINGLE_INTERVAL_SELECTION lets you select
one interval via mouse and SHIFT key
-MULTIPLE_INTERVAL_SELECTION lets you select
via mouse, and SHIFT and CONTRL keys
Note: this tutorial is currently set up
to allow for this to be changed via
TogggleButtons with ActionListeners attached
to them so this code is commented out.

/******************************************************
Create and edit the TextArea and determine its
characteristics. A TextArea is a component
that allows you to enter text into the box via
keyboard input. You can select text by using
your mouse or pressing shift and the left and
right arrow keys.
The only difference between a TextArea and
TextField is that a TextArea can have
multiple lines of text
within it.
-setTextColor(Color4f): Determine color of
text within TextArea.
-setSelectionBoxColor(Color4f): Determine the
color that highlighting around the
selected text appears.
-setSelectionTextColor(Color4f): Determine the
color the selected text appears.
-setText("TextToBeDisplayed"): Determine
initial text within TextArea.
-setFont(FontName): Determine the Font
used within TextArea
-setSelectionStart(StartCharacterNumber):
Determine the character which the
selection will initially start after.
-setSelectionEnd(EndCharacterNumber):
Determine the character which the
selection will end before.
-setCaretPosition(Location): Determine the
location of the Caret within the TextArea.
Note: this does not do too much
currently because the only way
to cause the TextArea to gain focus is
to click within it, causing the
Caret to move.
