This method sets the name of the visual state to transition from.

Syntax

virtual HRESULT STDMETHODCALLTYPE SetFrom(
    const WCHAR* pFrom
) = 0;

Parameters

  • pFrom
    [in] Pointer to a string that identifies the name of the visual state to transition from.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

The following list shows examples of visual states that can be specified in the pFrom parameter:

  • Checked
  • Disabled
  • Focused
  • Indeterminate
  • MouseOver
  • Normal
  • Pressed
  • Unchecked
  • Unfocused

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.
