Examples

<Window
    ... >

    <Window.SystemBackdrop>
        <MicaBackdrop Kind="BaseAlt"/>
    </Window.SystemBackdrop>

</Window>

public MainWindow()
{
    this.InitializeComponent();

    SystemBackdrop = new MicaBackdrop() 
                        { Kind = MicaKind.BaseAlt };
}

Remarks

You can use MicaBackdrop to apply Mica material to an object that implements the ICompositionSupportsSystemBackdrop interface, typically a XAML Window.

Mica isn't supported on all systems. Where it's not supported, a solid color is used instead of the Mica effect.

Constructors

MicaBackdrop()

Initializes a new instance of the MicaBackdrop class.

Properties

Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
Kind	Gets or sets the kind of backdrop that the `MicaBackdrop` displays.
KindProperty	Identifies the `Kind` dependency property.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetDefaultSystemBackdropConfiguration(ICompositionSupportsSystemBackdrop, XamlRoot)	Retrieves a default `SystemBackdropConfiguration` object that can be passed to `ISystemBackdropControllerWithTargets.SetSystemBackdropConfiguration`. (Inherited from SystemBackdrop)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
OnDefaultSystemBackdropConfigurationChanged(ICompositionSupportsSystemBackdrop, XamlRoot)	Override this method to be called when the object returned by `GetDefaultSystemBackdropConfiguration` changes. This is useful if you're using a custom `SystemBackdropConfiguration`. (Inherited from SystemBackdrop)
OnTargetConnected(ICompositionSupportsSystemBackdrop, XamlRoot)	Called when this object is attached to a valid container; for example, when set on `Window.SystemBackdrop`. (Inherited from SystemBackdrop)
OnTargetDisconnected(ICompositionSupportsSystemBackdrop)	Called when this object is cleared from its container. (Inherited from SystemBackdrop)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
