GetInertiaParameterInteractionContext function (interactioncontext.h)

Gets the inertia behavior of a manipulation (translation, rotation, scaling).

Syntax

HRESULT GetInertiaParameterInteractionContext(
  [in]  HINTERACTIONCONTEXT interactionContext,
  [in]  INERTIA_PARAMETER   inertiaParameter,
  [out] float               *value
);

Parameters

[in] interactionContext

The handle of the interaction context.

[in] inertiaParameter

One of the constants from INERTIA_PARAMETER.

[out] value

The value of inertiaParameter. This value is one of the following:

• The rate of deceleration, in radians/ms².
• For translation, the relative change in screen location, in HIMETRIC units.
• For rotation, the relative change in angle of rotation, in radians
• For scaling, the relative change in size, in HIMETRIC units.

Return value

If this function succeeds, it returns S_OK.

Otherwise, it returns an HRESULT error code.
