indicate that the entire text will be selected when the TextBox gains the focus,
using the selectOnFocus Boolean variable. In addition, you can specify an
action function that is invoked when an action is fired on the TextBox . Typi-
cally, this is done when the user presses the Enter key.

There are two variables that hold the text, text and value . On supported plat-
forms, the variable text is updated as the user types. The variable value is
updated when the user commits the changed text on the TextBox . Typically, this
is when the user presses the Enter key or changes focus.
The TextBox skin implements the visual appearance for the TextBox and Table 5.2
defines the CSS attributes that are supported by the TextBox skin. The only way
to change these from the default is to use one of the CSS style sheet mechanisms
previously discussed. You can either use a style sheet and give its URL location
to the Scene object, or include a style string using the TextBox 's style variable.
