Using pref setter update#
However, if the content inside the Flyout can't receive focus, you should update to the FlyoutPresenterStyle to let the FlyoutPresenter receive focus instead. To do this, set IsTabStop to true and TabNavigation to Cycle on the flyout presenter style.
Using pref setter how to#
This example shows how to let the FlyoutPresenter receive focus so that the content is accessible. Initializes a new instance of the Flyout class. Gets or sets a value that indicates whether the element automatically gets focus when the user interacts with it. Gets or sets a value that specifies whether the control can receive focus when it's disabled. Gets or sets a value that indicates whether animations are played when the flyout is opened or closed. Gets the identifier for the Content dependency property. Gets the CoreDispatcher that this object is associated with.
Using pref setter code#
The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. Gets or sets a value that specifies the control's preference for whether it plays sounds. Gets or sets the Style applied to the Flyout content. Gets the identifier for the FlyoutPresenterStyle dependency property. Gets a value that indicates whether the input device used to open the flyout does not easily open the secondary commands. Gets a value that indicates whether the flyout is shown within the bounds of the XAML root. Gets a value that indicates whether the flyout is open. Gets or sets a value that specifies whether the area outside of a light-dismiss UI is darkened. Gets or sets an element that should receive pointer input events even when underneath the flyout's overlay. Gets or sets the default placement to be used for the flyout, in relation to its placement target. Gets or sets a value that indicates whether the flyout should be shown within the bounds of the XAML root. Within subclasses, you can override read-only properties using Computed Properties.Gets or sets a value that indicates how a flyout behaves when shown. Print(view.width) // Prints: "320" Overriding Computed Properties Let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 480)) We could, for example, create quick access to the width and height of a view:
Our Computed Property name is now our public access point to the inner content value without letting implementors know too much about our backing model.Ī great thing about Computed Properties is that you can use them inside extensions too. Print(viewModel.name) // Prints: "SwiftLee Post" Var viewModel = ContentViewModel(content) Var content = Content(name: "swiftlee-banner", fileExtension: "png") A setter can be useful when you want to prevent access to a more enriched object in your instance.įor example, we could keep our model object private inside a view model while we make a specific property accessible with both its getter and setter: Until now we’ve only covered read-only Computed Properties while it is possible to also add a setter. Using a Computed Property to disclose rich data However, it’s best-practice to simplify the code and remove it as it’s not adding much value if you know what computed properties are (which you do after this post! 😉 )
You could make this more explicit by adding the get wrapper around your computation: The filename property is read-only which means that the following code would not work:Ĭomputed Properties are readonly and setters wont work. Note that we could simplify this code by removing the return keyword: Print(content.filename) // Prints: "swiftlee-banner.png"Īs you can see, the filename property is computed by combining both the name and fileExtension property. Let content = Content(name: "swiftlee-banner", fileExtension: "png") A computed property to generate a filename. In the following example, we’re creating a filename based on the name and file extension: It can be used in several ways.Ī common use-case is to derive value from other properties. Try it today! What is a Computed Property?Ī Computed Property provides a getter and an optional setter to indirectly access other properties and values.
