    const WCHAR* pFrom
) = 0;

Parameters

pFrom

Specifying a state to transition from, by calling this method, is optional. A visual transition can be restricted to apply to only certain states, or it can be applied any time that the control transitions between states. You restrict when an IXRVisualTransition object is applied to the control by calling IXRVisualTransition::SetTo and IXRVisualTransition::SetFrom.

The following table describes the levels of restriction, from most restrictive to least restrictive.

Type of restriction	Value to set in SetFrom	Value to set in SetTo
From a specified state to another specified state	The Name of an IXRVisualState	The Name of an IXRVisualState
From any state to a specified state	Not set	The Name of an IXRVisualState
From a specified state to any state	The Name of an IXRVisualState	Not set
From any state to any other state	Not set	Note set

You can have multiple IXRVisualTransition objects in a collection that belongs to an IXRVisualStateGroup that refer to the same state. However, they will be used in the order that this table specifies.
