Connect to ChangeValue signal.

The ::change-value signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user initiates a value change.

Applications should not connect to it, but may emit it with [gobject.global.signalEmitByName] if they need to control the cursor programmatically.

The default bindings for this signal are Up/Down and PageUp and/PageDown.

`after`	Yes.After to execute callback after default handler, No.After to execute before (default)
