The View namespace provides methods for showing and dismissing views.

static function View.push(Item page) → Item

static function View.push(element()->Item page) → Item

Push the page. Pushing is usually used to navigate a view heirarchy, and creates a "back" relationship between the pushed view and the pushing view. Pushed views are always maximized and replace the previous view.

You can pass an Item instance, or an Item element to push. The following two examples are equivalent:

View.push(new MyPage {})

The optional arguments to push are:

optional Item context = null

The context in which to push the view.

The context determines where in the application's view hierarchy the page is pushed. Zing searches the container chain, starting with the provided context, until it finds either a StackView instance or an Apple.TabView tab.

If it finds a StackView, the page is pushed into it, as though the StackView.push() method was called directly on it.

If it finds an Apple.TabView tab, the page is pushed at that point. This allows each tab to maintain its own navigation stack, which is what users normally expect.

If neither is found, or if the context is not provided, the page is pushed into the "global" navigation stack.

optional View.Transition transition = .Default

The transition to use for the push.

static function View.present(Item page) → Item

static function View.present(element()->Item page) → Item

Present the page modally.

You can pass an Item instance, or an Item element to present. The following two examples are equivalent:

View.present(new MyPage {})

The optional arguments to push are:

optional View.Transition transition = .Default

The transition to use for the present.

optional View.BackgroundEffect backgroundEffect = null

In the case of a modal sheet, the backgroundEffect argument allows you to control the effect used behind the sheet to dim the content beneath it.

static function View.dismiss(Item page)

optional View.Transition transition = .Default

The transition to use for the dismiss. If a transition is not supplied the visual opposite of the push or present transition is used.

optional Bool closeModalGroup = false

When set and the view is part of a modal navigation stack, the entire stack is dismissed.

extension property View.StatusBar View.statusBar: .Default


Show the project default statusbar, as specified in the project settings.


Show the dark style statusbar.


Show the light style statusbar.


Do not show a statusbar.

extension property Bool View.autoHideHomeIndicator: false

When set, the iOS home indicator will be hidden automatically if the system determines it is appropriate to do so. This can be useful in fullscreen content viewers, such as video players, where the home indicator would be visually distracting.

Note that this property is a hint, and setting this does not always guarentee that the home indicator wont be shown.

extension property View.InterfaceStyle View.interfaceStyle: .Default


Use the default interface style.


Always use the light interface style.


Always use the dark interface style.

extension property View.PresentationStyle View.presentationStyle: .Default


The default presentation style.


The view is maximized to cover the entire available area.


On large screens, such as an iPad, the presented view is centered on the screen and slightly smaller than the Default presentation style.

On non-large screens, FormSheet behaves like Default.

extension event View.activated()

extension event View.deactivated()

Emitted when a view is activated or deactivated in a StackView or TabView.

extension event View.dismissing()

extension event View.dismissed()

Emitted when a view is dismissed, either by explicitly calling View.dismiss(), or implicitly by a back button or key.

The dismissing() event is fired when the dismiss begins, and the dismissed() event once the dismiss transition animation has finished.

Both the dismissing() and dismissed() events are always emitted. If there is no dismiss transition, the dismissing() event is emitted, immediately followed by the dismissed() event.

enum View.Transition

The transition to use when displaying and dismissing the view.


Use the default transition, which is Navigate for a push(), and SlideUp for present().












extension property Bool View.hasBackNavigationread only

Set when this view was push()ed to a navigation stack with previous views.
