getLabel(This) -> unicode:charlist()
Returns the control's label, as it was passed to setLabel/2.
Note that the returned string may contains mnemonics ("&" characters) if they were passed to the setLabel/2 function; use GetLabelText() (not implemented in wx) if they are undesired.
Also note that the returned string is always the string which was passed to setLabel/2 but may be different from the string passed to SetLabelText() (not implemented in wx) (since this last one escapes mnemonic characters).
setLabel(This, Label) -> ok
Sets the control's label.
All "&" characters in the label are special and indicate that the following character is a mnemonic for this control and can be used to activate it from the keyboard (typically by using Alt key in combination with it). To insert a literal ampersand character, you need to double it, i.e. use "&&". If this behaviour is undesirable, use SetLabelText() (not implemented in wx) instead.
