autoUpdateProperty

Should value change while typing into the text-field?

The default is false. i.e. value will only be updated when the spinner loses input focus, or when the Enter key is pressed. This mimics JavaFX's behaviour.

For simple forms, using autoUpdate = true may be more user-friendly, because invalid input is highlighted immediately.

However, in other scenarios, autoUpdate = true may be jarring. For example, suppose we have spinners to set the X and Y positions of an object. It may be jarring to see the object moving wildly as we type.

As this is Stylable, you can set this from within your Theme (and therefore all spinners will behave the same). You could also set it based on context. For example, spinners in a "form" use autoUpdate == true, but spinners in a Toolbar use autoUpdate == false.
