Sets the receiver's text.
<p>
This method sets the widget label. The label may include
the mnemonic character and line delimiters.
</p>
<p>
Mnemonics are indicated by an '&' that causes the next
character to be the mnemonic. When the user presses a
key sequence that matches the mnemonic, focus is assigned
to the control that follows the label. On most platforms,
the mnemonic appears underlined but may be emphasised in a
platform specific manner. The mnemonic indicator character
'&' can be escaped by doubling it in the string, causing
a single '&' to be displayed.
