/**
|
|
* @defgroup Spinner
|
|
*
|
|
* A spinner is a widget which allows the user to increase or decrease
|
|
* numeric values. By default the spinner will not wrap and has a label
|
|
* of "%.0f" (just showing the integer value of the double).
|
|
*
|
|
* A spinner has a label that is formatted with floating
|
|
* point values and thus accepts a printf-style format string, like
|
|
* “%1.2f units”.
|
|
*
|
|
* Signals that you can add callbacks for are:
|
|
*
|
|
* "changed" - Whenever the spinner value is changed by the user.
|
|
* "delay,changed" - A short time after the value is changed by the user.
|
|
* This will be called only when the user stops dragging for a very short
|
|
* period or when they release their finger/mouse, so it avoids possibly
|
|
* expensive reactions to the value change.
|
