An individual item that will be displayed by a StackNavigator
component.
Provides the view, an optional function to set properties before the view is
displayed, and an optional list of events to map to actions (like push, pop,
and replace) on the StackNavigator
.
The following example creates a new StackItem
using the SettingsView
class to instantiate the view instance. This item is given am id of
"settings"
. When the view dispatches the
SettingsView.SHOW_ADVANCED_SETTINGS
event, the StackNavigator
will push
a different item with the ID "advancedSettings"
onto its history stack.
When the view instance dispatches Event.COMPLETE
, the StackNavigator
will pop the view from its history stack and return navigate to the previous
view.
var item = StackItem.withClass("settings", SettingsScreen, [
SettingsScreen.SHOW_ADVANCED_SETTINGS => StackActions.Push("advancedSettings"),
Event.COMPLETE => StackActions.Pop()
]);
navigator.addItem("settings", item);

Static methods
staticwithClass(id:String, viewClass:Class<DisplayObject>, ?actions:Map<String, StackAction>, ?returnHandlers:Map<String, (Dynamic, Dynamic) ‑> Void>):StackItem
Creates a StackItem
that instantiates a view from a class that extends
DisplayObject
when the StackNavigator
requests the item's view.
staticwithDisplayObject(id:String, viewInstance:DisplayObject, ?actions:Map<String, StackAction>, ?returnHandlers:Map<String, (Dynamic, Dynamic) ‑> Void>):StackItem
Creates a StackItem
that always returns the same DisplayObject
instance when the StackNavigator
requests the item's view.
staticwithFunction(id:String, viewFunction:() ‑> DisplayObject, ?actions:Map<String, StackAction>, ?returnHandlers:Map<String, (Dynamic, Dynamic) ‑> Void>):StackItem
Creates a StackItem
that calls a function that returns a
DisplayObject
when the StackNavigator
requests the item's view.
Variables
popTransition:(DisplayObject, DisplayObject) ‑> IEffectContext
A custom "pop" transition for this item only. If null
, the default
popTransition
defined by the StackNavigator
will be used
instead.
In the following example, the stack navigator item is given a push transition:
item.popTransition = Slide.createSlideRightTransition();
A number of animated transitions may be found in the
feathers.motion.transitions
package. However, you are not limited to
only these transitions. You may create custom transitions too.
A custom transition function should have the following signature:
(DisplayObject, DisplayObject) -> IEffectContext
Either of the arguments typed as DisplayObject
may be null
, but
never both. The first DisplayObject
argument will be null
when the
first item is displayed or when a new item is displayed after clearing
the current item. The second DisplayObject
argument will be null when
clearing the current item.
