public Expander(java.lang.String label, boolean hasMnemonic)
If hasMnemonic
is true, the label will be interpreted as
containing Mnemonic characters (keyboard accelerators). If
characters in label are preceded by an underscore, they are underlined.
If you need a literal underscore character in a label, use '__' (two
underscores). The first underlined character represents a keyboard
accelerator called a mnemonic. Pressing Alt and that key activates the
button.
