Details

Constructors

HoverStateBehavior<TValue>(string)

Behavior that applies a property override when a view enters a hover state.

public HoverStateBehavior<TValue>(string propertyName);

Parameters

propertyName   string
Name of the overridden property.

Remarks

The override is added on pointer enter (i.e. when initiating hover) and removed on pointer leave.

Methods

OnAttached()

Runs after the behavior is attached to a target.

protected override void OnAttached();

Remarks

Setup code should go in this method to ensure that the values of View and ViewState are actually assigned. If code runs in the behavior's constructor, these are not guaranteed to be populated.

---

OnDetached(IView)

Runs when the behavior is detached from a target.

protected override void OnDetached(StardewUI.IView view);

Parameters

view   IView
The view that was previously attached.

Remarks

Behaviors may receive new views as part of a "rebind", if the old view is destroyed and recreated, for example as the result of a conditional binding changing states.

OnDetached is always immediately followed by OnAttached(). A behavior cannot remain in a detached state; however, overriding this method gives behaviors the opportunity to clean up state from the old view (e.g. remove event handlers) before the new one is attached.

Also runs when the behavior is disposed, so detach logic does not need to be duplicated in OnDispose().

---

OnNewData(TValue)

protected override void OnNewData(TValue previousData);

Parameters

previousData   TValue

---

Update(TimeSpan)

Runs on every update tick.

public override void Update(System.TimeSpan elapsed);

Parameters

elapsed   TimeSpan
Time elapsed since the last update.
