## Detailed Description

ShadowStyle provides properties for rendering a drop shadow behind a DelegateStyle. It is available as the shadow grouped property on any delegate.

     button {
         background {
             shadow {
                 color: "lightgray"
                 opacity: 0.6
                 verticalOffset: 2
                 horizontalOffset: 2
             }
         }
     }

By adjusting scale and color, shadows can also be used to create glow effects. The following snippet adds a diffuse white glow to the handle of a Switch that intensifies when checked:

     dark: Theme {
         applicationWindow.background.color: "#1e1e1e"
         switchControl {
             handle.color: "white"
             handle.shadow {
                 color: "ghostwhite"
                 scale: 1.2
                 opacity: 0.6
             }
             checked.handle.shadow.scale: 1.5
         }
     }

Note: Types in Qt.labs modules are not guaranteed to remain compatible in future versions.

## Property Documentation

### blur : real

The blur of the shadow. A value of `0.0` produces a sharp shadow, while larger values produce a softer, more diffuse shadow. The default value is `10.0`.

### color : color

The color of the shadow. The default value is `transparent`, which means that no shadow will be drawn by default.

See also visible and opacity.

### delegate : Component

A custom QML Component that replaces the default shadow rendering. When set, StyleKit instantiates this component instead of drawing the default shadow.

### horizontalOffset : real

The horizontal offset of the shadow from the delegate, in pixels.

### opacity : real

The opacity of the shadow, from `0.0` (fully transparent) to `1.0` (fully opaque). The default value is `1.0`.

See also visible and color.

### scale : real

The scale factor of the shadow relative to the delegate. The default value is `1.0`.

### verticalOffset : real

The vertical offset of the shadow from the delegate, in pixels.

### visible : bool

Whether the shadow is visible. The default value is `true`.

However, since the default shadow color is `transparent`, the shadow will not be visible unless a different color is set.

See also opacity.
