public signal void value_changed (double value, string text)
The 'value-changed' signal is emitted when the current value that represent the object changes.
value is the numerical representation of this new value. text is the human readable text alternative of
value, and can be NULL if it is not available. Note that if there is a textual description associated with the new numeric value,
that description should be included regardless of whether or not it has also changed.
Example: a password meter whose value changes as the user types their new password. Appropiate value text would be "weak", "acceptable" and "strong".
