SetGestureStatus Method

Sets the interest of the object or control in a known gesture.

Declaration

[C++]

        HRESULT SetGestureStatus (
    [in] InkApplicationGesture gesture,
    [in] VARIANT_BOOL gestureStatus
);

[Microsoft® Visual Basic® 6.0]

        Public Sub SetGestureStatus( _
    gesture As InkApplicationGesture, _
    gestureStatus As Boolean _
)

Parameters

gesture

[in] The gesture that you want to set the status of.

gestureStatus

[in] The value of the gesture status. Set the value to TRUE if the gesture is being used or FALSE if it is being ignored.

Return Value

HRESULT value Description
S_OK Success.
E_POINTER A parameter contained an invalid pointer.
E_INK_INVALID_MODE InkCollector collection mode must be in gesture mode.
E_INK_EXCEPTION An exception occurred.
TPC_S_TRUNCATED Unsupported gesture.
E_INVALIDARG The flag is invalid.
E_OUTOFMEMORY Cannot allocate memory operation.

Remarks

To get the interest of the object or control in a known gesture, call the GetGestureStatus method.

The AllGestures Gesture ID is not supported by the InkEdit control and returns an error. Passing invalid Gesture IDs does not return an error for InkEdit, but fails for InkCollector, InkOverlay, and InkPicture.

For the InkEdit control, this method should only be called if the Status property returns IES_Idle.

Example

[Visual Basic 6.0]

This Visual Basic 6.0 example calls SetGestureStatus to turn off most application gestures and then to enable the chevron gestures. The example displays application and system gesture event information in a multiline text edit control, Text1, on the main form window.
