Detailed Description

SpinControl provides a styled SpinBox with increment and decrement buttons and optional minimum/maximum labels displayed above the input. It is used by the simulation control panel for properties annotated with @range, @minimum, or @maximum in the QFace IDL.

The spin box is editable by default, allowing the user to type a value directly or use the + and - buttons.

Usage

SpinControl {
    from: 0
    to: 255
    value: backend.brightness
    onValueModified: function(value) {
        backend.setBrightness(value)
    }
}
